dvd ntsc=> pal conversion & adding subtitles best way?expert opinion

[FulciLives]

My understanding is that all PAL DVD releases from film based movies are faster by 4% ... I mean even big budgest 100 million dollar movies do this.

You can't get around it unless you use the DGPulldown method but I'm not sure how well you can edit it afterwards and I thought you said you needed to do some editing?

- John "FulciLives" Coleman

P.S.
I forgot to mention that you should use a tall and skinny looking font for the SSA subtitles since you are burning them into a 16x9 WS anamorphic image and they will get change to a shorter fatter "look" so you want to pick a tall and skinny font to begin with.

My understanding is that all PAL DVD releases from film based movies are faster by 4% ... I mean even big budgest 100 million dollar movies do this.

I've seen retail PAL DVDs converted using each of the 3 ways I mentioned, speeded up, converted from 24->25fps by adding a frame or 2 fields every second (similar to, but not exactly the same as DGPulldown), and blended. You should hear all the PAL anime fans complaining about the blended anime DVDs they have to deal with. Yes, speeding them up is far and away the most common way to do it.

[poescp]

To check on Decomb, open the script in VDubMod and go to a place where the jerkiness occurs, advance a frame at a time looking for missing frames and duplicate frames. If you find anything, then the settings are most likely a little bit off.

i have done that and something interesting happens when i turn on show=true in decom. the passages that are jumpy are shown as "out-of-pattern". after that i went into the original ntsc movie and loaded it in virtual dub and guess what: the jerky passages are the passages that are not 3:2 pulldown, but are passages that are interlaced all the way through. there are only short major scenes where this happens, but that is very noticable. how would i handle this. basically most of the film is 3:2, except those two passages and also often inbetween individual frames that are out of pattern = interlaced. i guess i have film and non-film (interlaced) material, therefore i have tried to add Telecide(order=1,guide=1)
Decimate(mode=3,threshold=1.0), as mentioned in the decomb manual and it works better, however with the 2 scenes mentioned above each with perhaps around 30 frames that are interlaced (each one following another) after adding mode=3 two frames are smooth the next two unsharp and this continually until end of the 30 frames, thus making it slightly jumpy/jerky.

I'd be more inclined to suspect your player, unless you're seeing this when played in your standalone. So, just how are you playing the DVD where you see the jerkiness?

i see it in standalone player aswell, as also if i go virtual dub frame by frame. it just leaves out some frames, but does not dupplicate frames.

dgpulldown

i will also try the dgpulldown thing, as i did not check on the standalone when i last mentioned it was jerky.
my only thought is that i have to run the files twice via the encoder. would that not loose quality?

shorter fatter "look" so you want to pick a tall and skinny font to begin with.

what fonts do you advise? i am surprised that you mention it needs to be taler, i thought WS only blows things up in the width not hight

[manono]

Good for you. You've been reading the Decomb Reference Manual and applying what you've learned. It's very well written and very helpful. So, you have what's known as a hybrid, a mix of 2 different framerates, 23.976 and 29.97. There are several ways to handle it.

One is to split the encoding into 5 parts and reassemble them at the authoring stage. 5 because you have the 2 short interlaced sections, and then the progressive sections before, in between, and after. The 3 progressive sections would have pulldown applied, and the 2 interlaced sections would be encoded as interlaced 29.97fps, with no pulldown applied. The Trim command in AviSynth would be used to separate them into their 5 pieces, making 5 different .avs's. I do this often when I have a progressive video but interlaced end credits. It can make for perfect results, but it's a lot of work. Plus, unless there are some black frames where the different sections join, I sometimes get some garbage for a frame or 2 at the join. Not good.

A second way is to use Decomb as you used it, blending together half the frames during the interlaced sections. It's not perfect, but better than doing a normal IVTC. Not absolutely smooth playing, not absolutely clean and sharp, but better than the jerky playback you get with a normal IVTC. TIVTC has a similar way to handle hybrids.

The third way, and the one I prefer whenever possible, is to use SmartDecimate for the IVTC. It was designed for hybrid video. When it comes to the interlaced parts, it uses a bobbed field in place of a frame. Still some jerkiness, but much less than from a regular IVTC, and you get nice clean unblended frames out of it.

Only you can decide how you want to handle it. Maybe do some tests on small sections Trimmed out of the movie.

A SmartDecimate script might go something like this:

LoadPlugin("F:\DivX Stuff\GKnot\DGDecode.dll")
LoadPlugin("F:\DivX Stuff\GKnot\TDeint.dll")
LoadPlugin("F:\DivX Stuff\GKnot\AviSynth_C.dll")
LoadCPlugin("F:\DivX Stuff\GKnot\SmartDecimate.dll")
mpeg2source("D:\Zatoichi's Conspiracy\Zatoichi.d2v")
B=TDeint(Mode=1)
SmartDecimate(24,60,B)

You can get both SmartDecimate and TDeint here:

http://www.avisynth.org/warpenterprises/

i will also try the dgpulldown thing, as i did not check on the standalone when i last mentioned it was jerky.
my only thought is that i have to run the files twice via the encoder. would that not loose quality?

I don't understand. DGPulldown doesn't reencode, but only adds the flagging to make the 23.976fps video play back at 25fps from a PAL DVD player. The video quality will remain unchanged from what you got straight out of the encoder. You said you had a smooth playing MPV at one point, but said it only got jerky after applying DGPulldown. And since it should remain more-or-less smooth playing, I suspected the player as being the culprit, and suggested authoring it, or at least a piece of it, and trying it in your standalone. Or did I misunderstand your question?

I'll let FulciLives take the font question.

[FulciLives]

I'll let FulciLives take the font question.

Well I couldn't have said the other stuff nearly as well ... truth be told I hate doing the whole IVTC thing and since I live in the USA I'll just leave it 29.970fps in most instances. I admit though that for NTSC to PAL you really have to do an IVTC if the material is suitable.

As for the font ... hard to say which one exactly. I use subtitle workshop and you can see an example of the font you are picking.

Just try and find a font that kinda looks tall and skinny.

Remember you will be burning these subtitles onto a 16x9 WS enhanced video so when it plays back the subtitles will get wider ... if you use a "normal" font it will end up looking "squashed" when the 16x9 WS video gets resized on playback.

- John "FulciLives" Coleman

[manono]

Darn, you reminded me that my method #1 won't work, as he's making a PAL DVD. He can't encode at 29.97fps interlaced and reassemble the 5 pieces afterwards. Stupid me. I guess that leaves the 2 IVTC ways to handle the interlaced parts.

[poescp]

just to start with. thanks guys 100000 x. i really appreciate this and all your help. i feel like i am ending for the final lap in a race.
@Manano.

loadPlugin("F:\DivX Stuff\GKnot\DGDecode.dll")
LoadPlugin("F:\DivX Stuff\GKnot\TDeint.dll")
LoadPlugin("F:\DivX Stuff\GKnot\AviSynth_C.dll")
LoadCPlugin("F:\DivX Stuff\GKnot\SmartDecimate.dll")
mpeg2source("D:\Zatoichi's Conspiracy\Zatoichi.d2v")
B=TDeint(Mode=1)
SmartDecimate(24,60,B)

and then i guess add the AssumeFPS(25) , Crop(0,0,-12,-0) , LanczosResize(720, 576) bit?

dgpulldown re-encoding

what i meant is that i cannot feed the .avs script to dgpulldown, but first have to make an mpg file then have it run through dgpulldown with the result of an mpg file. at that time i have a video however still without audio, which usually i would add as part of the mpg creation in tmpgenc. how can i add the audio without having to create and mpg file and then again re-encode together with the audio to create the final mpg (in tmpgenc i can select the audio file location to be used and added to the .avs file which i load). hope that makes sence.
the other issue i have is that when i use procoder express for encoding it needs something i feed it with that already has audio (unlike tmpgenc here i cannot select the location of audio to be used).

I guess that leaves the 2 IVTC ways to handle the interlaced parts.

i will try the new IVTC method you mention as soon as i get back from work this afternoon.

A second way is to use Decomb as you used it

i could i still tweak it so not to have 2 frames sharp, the next two 2 unsharp etc..? is there a way?
is TIVTC a better command to use?

Maybe do some tests on small sections Trimmed out of the movie.

is there a aviscrypt command to do trimm. sorry, but i did not find it until now.


@FulciLives

That is what the AddBorders command does.

i understand that the 2 x 6 pix. border will not show on the final video due to overscan however i would like to have no borders at all ... what would i do here?

I use subtitle workshop

i also use subtitle workshop, however always open the file in Substation Alpha to set the format of font, select font, color, placement etc... because i believe i cannot do this in workshop or as part of a avisynth, or? what color do you use for fonts, as i heard this is critical so as not to have the subtilte flicker (no white). what grey values do you add?[/code]

[manono]

Hi-

and then i guess add the AssumeFPS(25) , Crop(0,0,-12,-0) , LanczosResize(720, 576) bit?

If you're going for the speeded up method, then yes. If you're going for the 23.976->25fps DGPulldown way, then no, leave off the AssumeFPS(25).

what i meant is that i cannot feed the .avs script to dgpulldown,

After the encode is finished, you feed the MPV to DGPulldown, and it gives you back an M2V ready for authoring. If you speed it up to 25fps, then the encoder output is ready for authoring.

how can i add the audio without having to create and mpg file

You add the audio during the authoring stage. Kind of basic stuff. Most authoring apps (but not all) want elementary streams, separate audio and video streams. If you're using an authoring app that requires an MPEG as a source (can't think of any, offhand), then maybe it's time to find a new one. Maybe you've just never tried to author separate audio and video streams.

the other issue i have is that when i use procoder express for encoding it needs something i feed it with that already has audio

I've never used it, but I seriously doubt it. I always keep my audio out of my encoder.

could i still tweak it so not to have 2 frames sharp, the next two 2 unsharp etc..?

No, that's how Decimate's Mode=3 works for the video portions. It takes 5 unique frames and creates 4 frames by blending them. From the DecombReferenceManual:

Nonfilm cycles are decimated by applying a frame blending decimation of the cycle from 5 frames to 4 frames. The resulting frame rate is the film rate (decimated by 1/5).

is TIVTC a better command to use?

TIVTC is an entirely different IVTC. I'm pretty sure it converts 29.97fps interlaced to 23.976 progressive the same way.

is there a aviscrypt command to do trimm.

Yeah, say you wanted to encode 1000 frames, from 1000 up to and including 1999:

Trim(999,1998)

Remember, AviSynth starts its frame count with 0.

http://www.avisynth.org/Trim

[poescp]

the script looks following way.

mpeg2source("F:\temp\new.d2v")
assumetff()
SmartDecimate(24,60,TDeint(Mode=1))
Crop(0,64,-12,-66)
AddBorders(6,0,6,0)
LanczosResize(720, 576)
TextSub("F:\temp\subs.ssa")
AssumeFPS(25)
converttorgb32()
Trim(1617,1670)
info()

with the info() bit i can see that parity states top field first, bottom field first changing the whole time there and back and also the video is then jerky (far worse than with telecide/decimate). it is however sharp, but far too jerky. perhaps there needs to be some adjustment?!?
by the way how do i get the black borders away (the 6 pixels on each side)

[manono]

Are you saying that the field order switches back and forth when you put Info() at the bottom of that script? Or when? And what happens when you open the vobs in DGIndex and run the Preview? Does it also say TFF? If you use a recent version of DGIndex, it corrects any field order changes automatically, unless you've turned it off in Options. I'm using v1.4.8Beta3.

Also, TDeint has an automatic field order finder built into it. What happens when you set it up the way I had it before (without AssumeTFF()):

B=TDeint(Mode=1)
SmartDecimate(24,60,B)

And if that's no good, what happens if you assign the field order:

B=TDeint(Mode=1,Order=1) #If TFF
SmartDecimate(24,60,B)

But you're right that SmartDecimate absolutely has to have the field order correct, or else it really messes up.

Why do you want to get rid of the small black bars on the left and right? You don't see them when watching on the TV, do you? Aren't they hidden by the overscan? And weren't you told that you crop 60 pixels from top and bottom to convert from 4:3 to 16:9? Yet you're cropping more than that? Maybe it's supposed to have some black on top and bottom to maintain AR, because there is black on the sides. I'm a little fuzzy on the math for what you're asking, so I'm not sure I can give intelligent advice about it.

[poescp]

Are you saying that the field order switches back and forth when you put Info() at the bottom of that script?

yes, 2 fields top, then 2 fields bottom and so on

Does it also say TFF?

yes

v1.4.8Beta3.

1.4.8Beta4

Also, TDeint has an automatic field order finder built into it. What happens when you set it up the way I had it before (without AssumeTFF()):

that's when jerkiness is available (using standalone dvd player).

B=TDeint(Mode=1,Order=1) #If TFF
SmartDecimate(24,60,B)

same, also jerkiness.

Borders. You don't see them when watching on the TV, do you?

you do not see them, but you see them in the little titlewindows (preview of dvd scenes). also i would like to have the material available for people to watch on PC without having borders on right and left side.
the issue of top and bottom borders are solved, i just did what FulsiLive said and it worked.

[manono]

OK, awaiting your sample, per the PM.

[poescp]

here it is. it's only the part where interlace is available. i have two scenes like it where there is no 3:2.

www.dieschafe.net/goodnews/er.demuxed.m2v

thanks a lot for looking at it.

[manono]

I PM'd you back. It's 29.97fps progressive with shifted fields. If anyone wants to look at it, see if you can get it progressive again. It's quite easy if you know a little AviSynth. Getting it back into the rest of the TV episode which is 99% film is a bit trickier, with no one right way to do it.

How do you get 29.970fps progessive with shifted fields?

- John "FulciLives" Coleman

[manono]

Hehe, this is what I wrote to poescp in the PM:

By shifted fields, I mean this; ordinarily, progressive material has the fields lined up like this (where the capital letter=top field and small letter=bottom field):

A B C D E F
a b c d e f

Hard to line them up. Supposed to have small letter right below the big letter. So, the top and bottom fields, fitted together, go to make up a progressive frame. With shifted fields, the bottom field is shifted over by a frame:

A B C D E F
b c d e f g

So they appear interlaced. You put them straight again like so:

LoadPlugin("F:\DivX Stuff\GKnot\DGDecode.dll")
LoadPlugin("F:\DivX Stuff\GKnot\Decomb.dll")
MPEG2Source("K:\Test\er.d2v")
AssumeTFF()
Telecide()

Telecide by itself, without the Decimate. That gives you progressive 29.97fps.

[poescp]

LoadPlugin("C:\Programme\AviSynth 2.5\plugins\Decomb521VFR1.3_P4-Athlon.dll")

Decimate(mode=3,threshold=2.0)
Crop(0,64,-12,-66)
LanczosResize(720,576)
TextSub("F:\temp\subs.ssa")
AssumeFPS(25)
converttoyuy2()

that's my final script i have decided on. decimate mode=3 does a great job even on the shifted fields part. obviously could be better, but will do and is hardly noticeable. the 5 part method is too complicated for me.
you know i want to have a simple script that will allow me to use it in premiere pro 2.0 (with avisynth plugin).

i have gone with arial narrow 51 bold, color: rgb 207, 207, 207, shadow 2, border 2 and that works great.

1)
i still however want to include the audio in the script however. is that possible adding it toward the end of the script? the reason is that i am sending the material directly to procoder express and it does not allow me to add audio there. if i frameserve the whole thing via virtualdubmpeg it turns everything back to rgb.

2)
the last issue is that i need to have a blank video and empty audio for the first 3 seconds of the film, because if the film starts straight away and straight away with the audio on one of my dvd players it kind of swallows, more so hast stuttering for the first fiew seconds of the film. how would i add this to the avisynth script?

[FulciLives]

As far as the subtitles go ... only you know if they look good ... just be sure they are not too low on the screen nor that they go to far to the edges (right/left sides) because every TV has OVERSCAN meaning you never see the extreme edges (all 4 sides) of the image.

As for the audio I already detailed on page 1 of this thread on how to use GOLDWAVE to adjust the audio which must be done since you are speeding up the video from 23.976fps to 25fps. Using separate tools (such as the suggested GOLDWAVE) is really the best way to handle the audio.

Once you get a new time corrected PCM WAV file from GOLDWAVE you can then use ffmpeggue to convert it to a 2.0 AC-3 audio file. I would go with a bitrate of 256kbps as that seems to be the "sweet spot" for 2 channel AC-3 audio. If you want you can use 224kbps or even 192kbps but do not go lower than 192kbps.

By the way I must say that I admire you for following through with all this ... AviSynth is a most powerfull video tool yet so many people either don't try or give up while trying to learn it. So good for you in working through all of this!

- John "FulciLives" Coleman

P.S.
Hopefully manono can help with the blank video part ... I never had to do that so I'm not sure how to go about it myself.

[poescp]

thanks for the compliments.
i have now given up on the script with the assume25fps and am using the script without that command feeding it via dgpulldown.

LoadPlugin("C:\Programme\AviSynth 2.5\plugins\DGDecode.dll")

Crop(0,64,-12,-66)
Lanczos4Resize(720,576)
TextSub("F:\temp\subs.ssa")
converttoyuy2()

there is only one thing i just do not understand´when making the m2v file for dgpulldown. i am using tmpgenc currently and i am not sure what i need to enter under the input and output.
do i do following: input: non-interlaced, top field first, 16:9 625 line pal (or do i choose ntsc?)
output: size: 720x576, 16:9, 23,976, video format PAL (or do i do NTSC), interlace (or non-interlace?)
this is where i am stuck. i have seen a lot of pal to ntsc conversion tutorials in use of TMPGEnc but not visa-versa.

by the way the reason i am not doing the assume thing is because of the speedup by 4 % and it is noticeable for the people reading subtitles, having to read them faster and the voice of the speaker being quite a bit higher/faster. also the goldwave thing is not bad, but when i want to keep the pitch and just speed the audio up it really does a bad job. but even if i keep the pitch the speaker still speaks fast.

[FulciLives]

I know how you feel about the PAL speed up thing. I have an old documentary that is hosted by William Shatner on NTSC VHS but the quality is horrible. I recently got a PAL DVD of it (sadly there is no NTSC DVD) and the audio speed up was most noticeable. As we all know William Shatner has a very unique way of delivering his ummm performance and with the 4% PAL speed up ... his performance was totally destroyed. I converted the PAL DVD to NTSC by slowing the frame rate and audio from 25fps to 23.976fps and now William Shatner gives a steller performance LOL

I understand how the TMPGEnc Plus settings can be confusing. When doing the NTSC to PAL conversion using the DGPulldown method you want to end up with a video that has a NTSC frame rate of 23.976fps but a PAL frame size (usually 720x576). So in essence you want the encoder to output a "hybred" and it is then DGPulldown that does it's little bit of magic in creating a PAL compliant video that will run at 25fps instead of 23.976fps

So how do you get TMPGEnc Plus to output a video with a PAL frame size of 720x576 but at a NTSC frame rate of 23.976fps?

Well you have to "trick it" meaning you cannot use the WIZARD MODE and if you use one of the pre determined PAL/NTSC DVD templates you need to "unlock" the template and "edit" the settings to give you the hybred output you need.

I don't have the time right now to show you but I will do that in a future post that will hopefully be later tonight ... if not then tomorrow for sure.

I'll actually post some screen shots of the TMPGEnc Plus settings so you can see what it is you need to do.

- John "FulciLives" Coleman

P.S.
If you want to try it yourself while I am away here is a quick run down of what to do. I would load the PAL DVD template and use all the basic settings it sets up (such as the GOP stuff etc.) but unlock it so that you can change the FRAMES PER SECOND from 25fps to 23.976fps ... make sure you do not do what is called a "soft" pulldown.

If that doesn't make sense then you will have to wait for me to post a more detailed method ... just don't have the time right now.

One last thing ... remember if using TMPGEnc Plus you need the last line of the script to read ConvertToRGB24() however you can use ConvertToYUY2() if using CCE aka Cinema Craft Encoder. Remember that the BASIC or LITE version of CCE is only like $58.00 US Dollars. You can use either method of NTSC to PAL conversion with CCE without converting to RGB as is needed with TMGPEnc Plus thus making CCE a much better choice. However if you don't have and don't want to spend the money on CCE then I wouldn't worry about it too much. In other words the difference in the TMPGEnc Plus output VS the CCE output is fairly minimal (knock on wood).

[vhelp]

Hi guys.

fwiw.. hehe..

Here's a version I processed poescp's U/L'ed clip through vdubMOD.
( took 10 minutes to upload <1mb file through dial-up, sheesh! )

** er.demuxed.m2v.vhelp.to.divX.avi

However, I'm confused, as to where you are having trouble inside your source.
Are you processing a "source video" that includes commercials (and encoding
those as well) ??

or just a tv program ??

Thanks,
-vhelp 4009

[poescp]

@ vhelp. this is only a part of a longer video. the other part it 3:2 pulldown, meaning i need to telecide via avisynth those parts at the same consindering that there are two small section, ie. would you have that have shifted frames. see post.

[poescp]

@FulsiLive

How to work TMPGEnc with templates unlock etc. is not problem for me far more what to enter:
AVANCED TAB: 16:9 PAL or NTSC.
VIDEO TAB: VIDEO Format NTSC or PAL

[vhelp]

@ vhelp. this is only a part of a longer video. the other part it 3:2 pulldown, meaning i need to telecide via avisynth those parts at the same consindering that there are two small section, ie. would you have that have shifted frames. see post.

Ahh, I see now

Then, I should have requested for something different. I should ammend my
request, and ask..

** Can you post a *new* file, with this mixture of, 3:2 and Field-Shifted ??

See if you can cut a good chunk, where it is 3:2 and then turns into Field-Shift,
so we get an idea how the fields "cut-off" between the two. You see, there may
be a way to process this type of source video with an AVIsynth "function" that
detects this cut-off.. say, function A will handle the 3:2 parts, while function B
will handle the field-shift parts. Hopefully, through the entire source video
file this way.

Can you post a new clip like this, thanks.

i think i will be giving up soon, and just use the horrible procoder express direct ntsc to pal (at least that does not give me any jerking, even though i know it's not nice way).

[manono]

Hi-

When you tested, did you test the whole video, or just that little section? The reason I ask is that when you cut it, you made it Bottom Field First, but you kept the DGPulldown setting as TFF. You reversed the field order, and that may account for the jerkiness you see. Just open them both in DGIndex (the MPV and the M2V) and run the Preview and you'll see what I mean. I redid it, this time unchecking the TFF checkbox. I'd like to say that it plays smoothly, but I can't tell. It's too bright where I am to clearly see that dark clip, and I'll have to wait until dark. I'll get back to you later on that.

Here's how you make a black video of 3 seconds at 25fps PAL resolution, in RGB24 for TMPGEnc:

BlankClip(Length=75,Width=720,Height=576,Pixel_Typ e="RGB24",FPS=25)#75 frames=3 seconds

http://www.avisynth.org/BlankClip

I would suggest joining it with the main video at authoring time. It's possible to encode it with the script for the main video, but it'll mean a major revamp of the script. As for the audio, to account for the 3 second intro black video, just delay the audio for 3 seconds, and add 3 seconds of blank audio at the beginning. Use AC3 Delay Corrector for this. Fill in the Start Delay of 3000 ms, and check the "Try Silence" check box.

Let me know if that solution is satisfactory. If not, there are other ways to do both the video and audio.

Edit later: Dark now. The field reversal didn't seem to make much, if any, difference. I play it in VLC player, and it's obviously jerky. I play it in MPC, and it's either very subtle, or it's smooth playing, not really sure. But if it's jerky in your standalone, then that's the main thing. That's all that counts. I guess the AssumeFPS(25) is the best way for you to go, along with speeding up the audio. I really wouldn't advise purposely blending anything. But it's your video to do with as you wish. Good luck.

I was hopping for a much lager video clip..
Actually, I was hoping for something a bit longer than your last clip.

To be clear, the point I'm trying to uncover here is the videos' consistancy
with how each "scene-change" lay out the sequences of fields.

Here's how your source seems to be laied out..

TbTbTb : iiPPPiiPPPiiPPPiiPPPiiPPPiiPPP ..

Without seeing *more* of your source's layout, perhaps it consists of something
like this, hyperthetically:

.. TbTbTb : iiPPPiiPPPiiPPP : TbTb : iiPPPiiPPP : TbTb : iiPPPiiPPPiiPPPiiPPP ..

where:

Field-Shifted..
** Tb (or 'T') TOP and 'b' for bottom (I really should just say, Interlace)

** : is scene-change

3:2 Pattern (or telecine)..
** ii is 2 interlaced frames
** PPP is 3 Progressive frames

Note, Tb is just my crude way of trying to explain the field's interlace pattern
prior to (your) sources 3:2 pattern.

- Now, there could already be a filter() plugin for AVIsynth that can process
this type of video source.. a mixture, that is. And, without it comprimising the
image with blends in certain areas.

I noticed several questions above related to procoder and should clear a few things up ..

procoder does a inverse telecine (IVTC) on telecine sources (unless you tell it not to) before encoding ...

procoder does speed up or slow down automatically to change frame rates - you set it in preferences on what the threshold is and turn on this option .. this only really works well with truly progressive sources ... outside the threshold, procoder will interpolate instead ...

@BJ_M i have procoder express, and there seems to be no threshold i can set

@vhelp i will upload a larger sample tomorrow. what i see however seems to be that there is no specific pattern. most is iiPPPiiPPPiiPPPiiPPPiiPPPiiPPP with two short scenes (one of which is uploaded) which is TbTbTb.
And occasionaly there seems to be a very short part (only a few scenes) which are TbTb (out of pattern when i enter telecide show=true), but nothing too bad because the scenes are only very short and no jerking noticable.

@all. would be great if you could have a look at the dgpulldown thing (the two files i uploaded) because it is really strange ... i have a perfect 23.976 .m2v file which after dgpulldown turns into parts that are jerky.
i do not want to do the assume25fps thing because it speeds up things and this is a big audioproblem when listning to the audio, very noticiable as most parts are spoken (long parts of dialog).
