20 hours of pal to ntsc wasted!

[dave_c]

alright, i need to know how to convert xvid pal to ntsc dvd properly using tmpgenc! i just wasted 20 hours of converting and only to ifnd out that all the converting did was make the video go faster due to the increased frame rate! also, when i played the converted video via media player, the video seemed to jerk/jump.

in the "video" tab, what should the settings be? in particular, what should i set "aspect ratio," "video format," and "encode mode"? according to gspot, the pal xvid has an aspect ratio of 2:35:1 or osmething and i don't know if it's non-interlaced or interlaced. according to avicodec, however, the aspect ratio is 2:21:1. don't know if they're synonymous (the aspect ratios).

how about under the "advanced" tab? "video sourcet ype" should be set to what? "field order"? "source aspect ratio"? "video arrange method"?

incidentally, i want the converted output to be full screen on my tv, but i don't want it to look stretched or anything. but if that's not possible, i guess i will live with some black. ahah.

also in the "advanced" tab, you're able to check a whole bunch of options. in particular, should i enable "3:2 pulldown," "de-interlace (none)," and "do not frame rate conversion"? i seen many guides that say enable "do not frame rate," but that doesn't make sense to me. don't you want the frame rate to be converted so that the frame rate gets converted from 25 fps (pal) to 29.97 fps (NTSC)?!?

idon't know if this matters, but the output NOT being progressive/non-interlaced isn't an issue, because i don't have a progressive scan dvd player and TV anyhow. so i don't see a point in making the converted output progressive/non-interlaced.

[dave_c]

well, if the second step of the project wizard correctly identifies the file, then the video is "non-interlace (content of video)," "1:1 VGA (aspect ratio) ," and "video movie (content of video)."

20 hours!!!! Bloody hell!! If u convert Pal to Ntsc in Tmpeg your outcome video is gonna be jerky.
can u leave it in pal? most dvd player's play ntsc and pal

[adam]

If properly done, converting PAL to NTSC is not jerky at all. It is literally no different then converting film to NTSC.

With all due respect dave_c there are guides on this site that explain exactly how to do what you want. I can't see how you could possibly have these questions if you read them. The guides tell you exactly what settings to use.

Your problem is that you converted 25 to 29.97. Obviously this is going to be jerky. The correct method is to first convert PAL back to film by slowing it down to 23.976fps. Then it can be telecined to 29.97fps properly, and this is something best left to your DVD player.

All you need to do is load the NTSC DVD template and then load the unlock template. On the video tab set output framerate to 23.976fps (29.97fps internally) and enable the 3:2 pulldown when playback option. (note this is on the video tab NOT the advanced tab- that is for performing a hard telecine which you really never want to do.) Now on the Advanced tab you need to enable the do not framerate conversion tab. By default TMPGenc uses frame duplication/decimation when doing framerate conversions. So when you slow your film from 25 down to 23.976fps it will randomly delete frames. By enabling this filter it will instead do the conversion properly and simply slow down the playback rate, while retaining all frames.

As far as the other settings on the advanced tab these are things that are not even particular to a PAL->NTSC conversion, they are basic settings which must be set everytime you use TMPGenc. There is at least one guide on this site which specifically explains what every single one of those options does.

You must also slow down your audio separately. For this you should use BeSweet and its built in regional format conversion options. Again, just look at one of the PAL->NTSC guides on this site.

Ok I did this entire process when I converted my PAL SVCD to an NTSC SVCD (I used the guides on this site) and my video was still slightly jerky, what does that mean? Also what is this telecine stuff your talking about, when do you do that for a PAL to NTSC conversion? I know theres an option on TMPGEnc called telecine but I have no idea how to use it. Right so iam kind of lost at the moment with both of these things.

-Jay. Telecine is the process of converting the video from 24fps to 30fps. Only 30fps (29.97) can play on your NTSC television set. It accomplishes this by combining the individual fields in a specific pattern. I think lukesvideo.com had a nice explanation of it. I've did some experimenting with the 3:2 pulldown thing with my Apex DVD player a while back. I found that my DVD player just duplicated frames. Maybe yours does the same. Try stepping through the video and see what happens.
Come to think of it, I got a new DD player. I may have to try it again.

[spiralnebula42o]

Ok I think I kinda gett it, when I do my pal to ntsc conversion should I mess around with the telecine setting on tmpgenc and set it to anything?

[Anonymous843]

You can use Canopus Procoder 2.0 xpress, which will do it automatically without any jerkiness. It only costs about $60 but it is the only encoder i know of that with do it the right way.

[adam]

But then that's not really the right way. You don't want to perform a hard telecine (physically convert to 29.97fps interlaced.) This is horribly inefficient and thus lowers quality. If you've got a 25fps progressive source then you basically have what can be easily turned into a perfect FILM source (~24fps). This kind of material should be stored at 23.976fps with pulldown flags. The DVD player will then do the proper conversion to 29.97fps interlaced as it plays. But since you only have to physically store 24 frames per second (20% less) and you only have to store progressive footage (inherantly easier to encode) rather then interlaced footage, you get a huge increase in quality. Film sources are almost never hard telecined to 29.97fps on commercial DVDs, they are always stored at 23.976fps. The only time you find 29.97fps is when the footage was shot that way, (extras, trailers, and the occasional full length feature.)

fmctm1sw I seriously doubt your Apex DVD player just performs a telecine by repeating whole frames. If this were the case then your commercial DVDs would also appear jerky, since as I said they are stored at 23.976fps as well. I think you must have done something wrong in the conversion.

spiralnebula42o you instruct the DVD player to perform a real time telecine when you enable the 3:2 pulldown when playback option. The only telecine option in TMPGEnc is to perform an inverse telecine. This is for converting 29.97fps interlaced material to 23.976fps material. Just use the settings I specified before. Those are the only ones relevant to a PAL->NTSC conversion.

Adam, this is what I speak of: https://www.videohelp.com/forum/viewtopic.php?t=211540&highlight=

It's been a while but I don't think I was I may try that again and see what happens. After I read your first post, I thought about the commercial DVD thing. I need to go back and look at this. I like the whole 23.97 fps with pulldown flag idea. Maybe I did do it wrong..

[adam]

fmctm1sw I know what your problem was in the other thread. You can't IVTC a 29.97fps VCD. VCDs don't support interlacing so once the telecine has been performed to give you your 29.97fps interlaced source, you have to throw out half of your fields when you encode to mpeg1. You have thrown out half of your temporal information which not only introduces that jerky quality on slow pans, but it makes any subsequent IVTC impossible.

A properly telecined NTSC DVD, whether hard telecined or soft telecined at playback, will not be jerky at all.

Adam, you have to manage audio separatly when converting using your settings in TMPGENC?

Skip the part about ripping the DVD and start with the TMPGEnc section.

If you use FAVC it automatically converts PAL to NTSC by using a pulldown technique. (DGPulldown 25->29.97 to be more precise.) It doesn't use TMPGEnc, but it produces comparable results.

[aguinsburg]

But FAVC can handle audio too? BTW, can it convert to MPEG instead of DVD?

[Mr_Odwin]

Yes, it handles audio too. It's more an automated DVD creator but it creates mpeg files as part of that process. Just look in the working folder that is created.

Well, hard solution at least. I need a single piece of software for conversion!
