Encode 640 x 288 AVI to DVD?

[sealos]

So I'm trying to encode an 640 x 288 AVI to DVD, but I'm having an issue where the picture gets squished. Is there a way to encode to DVD and retain this resolution? If not, how do I go about encoding to 16x9 or 2.35:1 without it looking distorted?

Cheers,

DVD has to be 720 by 480, 352x480, or 352x240

Once you decide if you want an aspect ratio of 16:9 or 4:3 by selecting either DVD, or DVD 16:9, you can simply set the size to 720x480 and use the automatic letterboxing feature and Decode with Quicktime either with mpeg2enc or ffmpeg. The mpeg2enc preset turns both of these on, but in ffmpeg you need to turn on deocde with quicktime to use the auto letterboxing.

To do it manually.

If you want an aspect ratio of 16:9
Encode at 720x384 and letterbox top and bottom 48

For 4:3
Encode at 720x288 and letterbox top and bottom 96

A 16:9 encoded video will play fine on a 4:3 TV since the DVD player will automatically add the extra padding required. You get better visual quality if you use a 16:9 asepct ratio even if you play back on a 4:3 TV.

I have this same avi and I have tried for days to get it as good quality as I can and for it to be the right aspect ratio.
I can get it to REALLY great quality by setting the Q-min and Q-max to zero. And the aspect ratio I do what it says here but I put the top and bottom at 54.
But when it is supposed to make the vobs it fails and says too many frame drops...
I have tried with the Qmin and max up like 2 and 20 and it seems to work but the quality is awful and not worth it. I use DVD ffmpeg and can't use the quicktime part.(can't get it to play in QT no matter what)
The original is a divx avi 23.98 fps. I have tried muxing after making a new mp2 from the original but no matter what it won't mix the two.

PLEASE--What is going on here, Is it because the orig is 23.98? Does it sound like the new .mpv is the problem/why? Is it my settings on Qmin and max? What would cause the video and audio to change and not be able to mux?

PLEASE ANYBODY HELP ITS DRIVING ME CRAZY.
Thank You for your time...

Try to disable "Normalize audio" in the audio tab and try again. In that case it should mux while encoding so the muxing will never fail.

For Popo's problem, turning off "normalise audio" may work, but he will then end up encoding at 29.97 since FFMPEGX when using ffmpeg ignores the 23.98 setting if "normalise audio" is off.

If you want non-normalised audio and 23.98 fps you have to do video and audio separately.

Thanks guys the normalizing off worked----but the file went up to 29.97 like you said. The .mpv and a burned dvd of the VIDEO_TS play great / exactly the way i want with my computers player but not in my sony stand alone player. I hear the audio fine but the video never plays right it just jumps and stops and gets blocky. I tried encoding the audio alone(no normalize) and muxing with a 23.98 video but that still won't mux.

Is this new one that works technically not 29.97,(it says it is when i drop it back in the program) would that cause it to not play in my standalone player correctly?

Why will this new one not work in my player but is perfect in the computer?

Reading some other posts that touch on this---I would try mpeg2enc(for 3:2 as part of the encoding into VIDEO_TS) but I need ffmpeg because it is the only way to get the correct aspect ratio.


Thank you all you are saviors...

If you encode with mpeg2enc and 'Decode with Quicktime' the aspect ratio should be always correct as 'Decode with Quicktime' has an automatic letterboxer.

By the way I fixed the ntsc vs ntsc film with 'Normalize audio' bug in forthcoming version 0.0.9t.

I can't use convert with quicktime cause after trying everything the file won't play correctly in quicktime...

If make a pulled down 3:2 .m2v file of the 23.98 what framerate do i set when I try to encode again or add different audio? Cause it always says 23.98 with 3:2 or somthing...
Or if mepegt2enc if 3:2 is pushed what framerate 29.97 or keep it the default 23.98 ??


THANKS

Pulldown is always applied to NTSC FILM framerate.
