Non-Standard Frame Rates, Demuxed Audio and FFMpeg

[Maikeru-sama]

Hi forum,

I have spent the last week changing how I encode my audio and video.

To make a long story short, before, I was just using AviSyth to make a script (via FitCD) and drag it into CCE with the Audio still in the Video.

Now, with the help of all the knowledgable folks on this forum, I now only use CCE for encoding my Video and use FFMpeg to encode or copy my audio.

Now, the only question I have is what do I do when I get a Non-Standard Frame Rate (Or Non 23.976/29.97)?

Let's say my video that I want to put on a DVD has these specs:
Name = Video.avi
Container = AVI
FPS = 20.00

Now, in the past, as I told you, I would just use Avisynth with Audio/Video together and use a script 45Tripp or Jagabo or somebody gave me a long time ago to do this and it works 100% of the time (they also showed me a way to do it with DGPulldown but I like the below better):

<AVISYNTH>
AVISource("C:\input.avi")
LanczosResize(640,336)
AddBorders(40,72,40,72)
ChangeFPS(59.94)
SeparateFields()
SelectEvery(4, 0, 3)
Weave()
ConvertToYUY2()
</AVISYNTH>

Now, since the Audio is separate, if I do this on the Video in CCE, then the Audio is going to be out of sync. That leaves me with 2 questions:
1) Does FFMpeg take AviSynth Scripts?
2) Can I write some type of script like the one provided for the Video, but for the Audio to make sure they are in-sync?

Hi,
Newer builds of ffmpeg handle AVS scripts very well, just make sure the build has Avisynth support which will be in the documentation. I use AviSynth and dump my scripts into WinFF (an ffmpeg GUI) all the time. As far as the Audio sync issue I'm not sure what to advise. I'm sure one of the experts will weigh in and tell you soon enough. Best of Luck!
