AVI to DVD MPEG (CCE or TMPGenc encoders)

[DJRumpy]

Odd about your audio. The M2V/MPV video file and the .MPA/M2A audio file should have the same duration. Check both after cce finishes encoding.

You did check your source AVI to ensure it is also in sync at the end?

Hi,

I've done a couple of encode, author, burn cycles and was not satisfied with the results. The last one was with a separate *.ac3 audio file and *.mpv from CCE. I authored it to DVD files but decided to check the lengths before burning with these results:

movie.mpv:
TMPGNec Author: 1:44:49
AVICodec: 1:44:42
Goldwave: wouldn't read it

movie.ac3:
TMPGNec Author: didn't know how to read it
AVICodec: 1:44:48
Goldwave: 1:44:48.219

movie.avi: (basic before *.avs script)
TMPGNec Author: results in *.mpv above?
AVICodec: 1:44:42
Goldwave: 1:44:42

Are the values in *.mpv and *.ac3 close enough to get a well sync'd video and audio? If not, how can I sync them? Should I use another authoring application other than TMPGNec Author?

Thanks for your help.

[DJRumpy]

You could stretch the audio. Apparently yours has a few bad frames in it. When you demultiplex it from the avi, the sync the audio had with the video is lost. Stretch the audio's length to match the video's length with Goldwave and then encode it to AC3 or MP2 (you can't use AC3 in TMPGenc unless you by the AC3 support).

Hi,

I did another encode, author, burn cycle last night leaving the embedded audio in the *.avi file. The audio was very close to being in sync with the video. The video filled the legacy TV screen thanks to Autocrop; however, the video has flaws in some places. This is what I mentioned before. I'll try to be more specific. The video is a little grainy in spots, then becoming so that I can see the rectangular pixels(?) that make up the picture. This is especially true in fast action scenes. Is there a filter that I can include in my *.avs script or another way to fix that? What if I encoded using TMPGEnc Plus or Xpress?

You are very correct that CCE is faster than the other encoders. It has allowed me to make twice as many bad encodes as I could have otherwise.
:P

[DJRumpy]

Again, check the same scenes in your original AVI for those same qualities. It's very unlikely that your getting bit shortages in a dvd project. It's more likely that those flaws are in your source AVI.

I get the impression that it wasn't done by someone who is experienced in encoding something in an AVI container.

Errror message when I drag avs file onto VitualDubMod

Avisynth open failure: I dont know what "clip" means

okay I followed the instruction on p1. I have an audio source in MP3 but when I open with VirtualDubMod it did not give me an error message. So I saved the audio source as wave. So then I follow the script using option 2

AVISource("c:\downloads\movie.avi",False)
WAVSource("c:\downlads\movie.wav")
AudioDub(clip,aud)
ResampleAudio(48000)
LanczosResize(720,480)
ConvertToYUY2()

So should I delete line 3? I thought I need to have option 2 therefore line 3 cos I converted my aud avi in MP3 to Wav earlier on in VirtualDubMod.

Thanks in advance

[jimmalenko]

Try this:

clip=AVISource("c:\downloads\movie.avi",False)
aud=WAVSource("c:\downloads\movie.wav") 
AudioDub(clip,aud) 
ResampleAudio(48000) 
LanczosResize(720,480) 
ConvertToYUY2()

[DJRumpy]

Your first three lines should look like this:

clip=AVISource("c:\downloads\movie.avi",False)
aud=WAVSource("c:\downlads\movie.wav")
AudioDub(clip,aud)

Thanks so much for the guide DJRumpy. This was my first go of converting avi to dvd. Though I did have a few hiccups which I'll get to in a moment, this guide was very easy to follow and explained well enough that someone like me with no previous experience can jump in and do a conversion.

If done properly, should the final result be 1:1? IE a 200mb xvid will result in a 200mb mpv/mpa? The smallest size I've reached is a 400mb mpv/mpa from a 200mb avi and the quality was really bad. Very good quality was achieved at almost 600mb mpv/mpa. I did this by reducing the average from 9500 to as low as 1500. I'm sure I didn't explain enough for help so I will post a picture tomorrow showing my settings in gspot and CCE. I look forward to making this perfect! Great start so far though

[kschang]

No, 200MB XVID will balloon to 600MB to 1 GB MPG file.

However, you should NOT count this way. The idea is to use as much space on the destination as possible by maximizing the bitrate in the MPEG file, thus maximizing the end quality while still fit on the media.

Don't worry about perfect or not. Just create an image file from what you got, and try playing the image, and if image plays, you can then determine if your end result needed further tweaking/redo.

[DJRumpy]

Exactly. The AVI containers commonly used today use MPEG4, which can compress a video file bar better than old MPEG2 that you see on DVD's.

Use a bitrate calculator to figure out your maximum average bitrate for your project based on the type of DVD your buring it to. Check the Tools section to find one to your liking.

Thanks for the tutorial =)
Now i have a problem with a xvid aprox 44min (29.976), i set the CCE to 29.976, the main window of CCE tells me that the duration is the same that gspot give me, but when i see the encoded video its complete but the lenght is 14 min (in 29.976).
What can be the problem? i encoded like 10 videos and this is the first time im having this problem
thanks

[DJRumpy]

What are you verifying the encoded MPEG length with? Also, are you sure your input AVI is 29.97 fps?

[RH+]

I am playing it with bsplayer or WMP classic, (with bsplayer i test all the encoded videos, and they are all ok, not this)
this is what gspot tells me:


thanks

[manono]

GSPOt says your AVI is 23.976fps. You shouldn't set CCE for 29.97fps if that's the case. What made you think it was 29.97fps?

[RH+]

Thanks for the tutorial =)i set the CCE to 29.976

i set it to 29.976 the problem must be in another setting....i think
thanks

[DJRumpy]

GSpot says your source AVI was 23.976, not 29.97. You set the wrong framerate.

Set it for 23.976 and you should be fine.

[RH+]

:O sorry i write wrong :S i set it to 23.976 in CCE and im having problem with that setting

[manono]

...but when i see the encoded video its complete but the lenght is 14 min (in 29.976).

Well, if it's complete, and if it doesn't play super-fast, then obviously it's not only 14 minutes long. Don't trust most players to give you the correct length, no matter if you've had good luck in the past.

Go ahead and author and see how it plays, and if it's complete.

Sorry if I'm responding to this thread late (and I don't remember if I posted in this thread) but I was wondering what would I have to type in my avisynth script to do batch encoding? I usually do batch encoding with TMPGEnc but I'm getting tired of it taking hours upon hours (read: all afternoon and all night).

[jackaction]

First of all thanks for this very informative guide, it is very useful. I came across a DVDRIP (.avi) with an AR of 640*256 (2.5).
So, this is the AVISynth Script I used in CCE SP Ver. 2.7.02.10.

clip=AVISource("Movie.avi", False)
aud=WAVSource("Movie.wav")
AudioDub(clip,aud)
ResampleAudio(48000)
LanczosResize(720,360)
AddBorders(0,60,0,60)

Well the resulting Movie came out with the width cropped on the left and right side. This is the first time I came across an AR of (2.5). I searced the forum and read about aspect ratios but am still not clear about it. This is what I found searching this forum concerning the AR of 640*256.

"Agreed. I would rather see letterboxing than chop a video up. Even when I had a 4:3 TV, I much preferred the letterboxed editions. To find out what ot resize it to, just divide the true width by the aspect, or multiply 480 by the aspect.

Since the true width is much wider than what normally goes into anamorphic dvd, i'd probably try dividing 852 / 2.50 to get the image width.

852 / 2.50 = 340

Round that to the nearest 8, which is 348.

Resize your video to 720 x 348 and add letterboxing to fill the 348 out ot the full 480 height. Encode it as 16:9."

I would appreciate if anyone could help me with my AVISynth Script and what else to do. Thank you for your time.

[manono]

Hi-

He's saying:

LanczosRezize(720,348)
AddBorders(0,66,0,66)

and then encode for 16:9.

He could be right, assuming the original 640x256 AVI was cropped and resized properly. Your script could be right, if the source AVI doesn't have the proper AR. I don't think there's any real way to tell at this point, except by resizing it by 16:9 and looking for a sun or moon or something round to see if it's really round, and not a slight oval. Either way, even though one or the other (or both) will have a slightly bad AR, the error might be so slight that you won't be able to easily tell.

[jackaction]

Thanks for the fast reply manono. I will give it a try and post my results. Always appreciate you knowledgable folks.

[jackaction]

Thanks very much for the info. My video came out perfect using that resize. I also used the same resize for a 2.438 AR and it also came out perfect.
I read of an AVISynth script GUI, so I guess I'll be searching for that next.
Thanks again

[manono]

You can get the scripts from FitCD pretty easily. For a GUI, maybe you're thinking of AvsEdit. Not sure.

[dnan]

i have a litlte problem....

when i'm encoding an .avi file (eg an episode from LOST)and choose 16:9 aspect ratio(wide screen),

this is what i get:





Pls smn answer 'cause in a few days i have to have all the season 2 burned on dvds. [/img]

[manono]

Get your AviSynth scripts from FitCD and set "Blocks Overscan" to 0.

[dnan]

Thx dude!

1 more quetsions:

which is the difference between the RGB color model na the YUY2 one?

edit:Is FitCD the best Avisynth scripter out there?


edit2: When I select this options in FitCD


and these ones in CCE


this is the result pictureit's too wide screen )


what the hell I have to do? pls help... [/img]

[dnan]

pls...someone answer...

sorry for the double post :P

[manono]

You made the script non-anamorphic (4:3), but you encoded for 16:9. Either encode that script for 4:3, or check the anamorphic box in FitCD and then use the changed script to encode for 16:9.

The YUV2 checkbox is for CCE (you), and the RGB checkbox is for encoding with TMPGEnc (not you).
