More Questions about 119 FPS

Post by Kero777 » Sun Aug 12, 2007 3:23 pm

I saw what was written in a thread a while back about 119FPS. Someone suggested getting the package at the bottom of the first post here:
http://forum.doom9.org/showthread.php?t=82264, the
avi_tc_package v1.5 package, but I took a look at it and I'm not sure what the process really consists of or how to do it. Is it script you use with Avisynth or is it a program? The zip file looks like it contains four different applications and I'm not sure if I need all of them.
I understand that it's the process of removing dummy frames and then using Avisynth's AssumeFPS() to convert it to the framerate I need if it's not already all set, but does anyone know where I can find a guide to do all this? I need my footage to be lossless at 23.976FPS. :)

Run the gui exe.
I think you use the stuff under the first tab. If it doesn't seem to work right, try the 2nd tab. Load your video, and then it will let you output a new video, and a text file. The new video will be 29.97fps, and you can discard the text file.

Ah, thank you very much, Zarxrax. :D I tested it out on one and then just used AssumeFPS(23.976) in Avisynth. Before I used AssumeFPS(23.976) it was playing MUCH faster... more than 5 minutes shorter than the original. After I used it, it turned out about 40 seconds longer than the original for some reason. It looks like it's playing at it's normal speed at most of the parts though (Hey, it's better than five minutes shorter. :D) The quality doesn't seem diminished at all, but I do not have audio. I assume it's because the speed is technically changed. I do not really need it anyway though. I used the v1 timecode file under mode during the process is the package. Is that the right/best option?

If you're using it for editing, why does it matter if you have audio? I've always wondered why so many people make a big deal about having the audio around here, especially since having it in the video is really tacky and most cons don't allow it for copyright issues...

119fps is used to make AVI 'support' variable frame rate - some parts were 29.97, others were 23.976. When set at 29.97, which in this instance was the minority, it plays the 23.976 footage as 29.97, which accounts for the five minute thing. When played at 23.976 like most of the footage should be, the 29.97 segments get slowed down, but due to their relatively minimal presence the huge discrepancy isn't there.

If you wanted the exact same time length as the original, you'd have to use the timecode to put the video stream into a MKV and have the proper variable framerate, then use DirectShowSource and specify the fps=29.97,convertfps=true parameters before decoding it back. However, that would be more or less wasteful since it would be adding a lot of frames you don't need - you'd be better off isolating the 29.97 segments, use Decimate on them (which may or may not cause jerkiness), and then reattach.

Actually, you're right: I don't need the audio. That's a problem of mine solved. It takes up more space anyway. :P

Reading that, I think it's best if I just keep it the way it is instead of re-attaching it (I may still try though). I can always slow down/speed up parts in Vegas as needed. I'm starting to understand this a lot better now. Thank you!
