Custom Framerate

[lordbelial]

Im trying to convert Dave Chapelle - Killing them Softly HBO Special. I have a Divx copy I downloaded and its 14.993fps. When I convert it it changes it to 23 fps and the video speeds up past the audio. Is there any way to force DVD2SVCD to encode the video at the original 14.993 fps?

Even if there is a way (which I don't believe there is), you aren't going to like the output as it won't work in your DVD player, and most likely not in anything else.

aren't there programs out there (vdub?) that will change the framerate of the video? once this is done you can remux the new video with the old audio in virtual dub also and then use that avi file as the input for avi2svcd.

I am no expert on this, but I hope I can shed some light.

There is a line inserted into the Avisynth file (that you can edit out, but I don't know the consequences of doing this) that says:
assumefps(23.976) for NTSC and (25) for pal.

Also the encoders (audio and video) are setup for standard framerates.

Since the goal of this program is to make the video work on a TV it must have the proper framrate or will look horrible.

I honestly don't think you can make a non standard framerate video with DVD2SVCD.

VirtualDub will change the video frame rate but since it has to add so many more frames the video looks sped up enormously. If anyone knows how to convert 15fps to 23fps wothout that happening please msg me.

I just looked and in TMPG you can encode at many different frame rates. I don't know how well it will work, but give it a try if your goal is to watch it on the computer.

If it's just an issue with the audio there are programs that will stretch it. It will affect the pitch though.

Not to try and get on your bad side, but that wouldn't do anything for the audio, would it?
Wouldn't the audio still be out of sync since the framrates will be different or is there a normalization of framerates in BeSweet?

Since it was an HBO TV show it was probably 29.97fps to begin with, so perhaps it would be better to use that framerate.
Try:

ChangeFPS(29.97)


This will duplicate frames to reach the desired framerate, it will not affect audio sync. You could try it with 23.976, but you will probably get jerky playback.

Just one for the future:

GoldWave has an option to stretch the audio without affecting the pitch, I just don't know how it would work with such a big increase in the audio length.
