Microsoft High-Speed MPEG-4 V2 (MP42)

Postby Kevmaster » Mon Sep 27, 2010 1:43 pm

I have a video file I downloaded from Youtube with the DVDVideoSoft FreeYoutubeDownloder. (Just for the record: It's a free live clip from a concert, no illegal material ;) )

When I try to drop it into VirtualDubMod I get the following error:

So how can I convert the file to use it for editing?

Use avisynth. That said, use a less retarded decoder and/or download format. I HIGHLY doubt that Youtube uses Microsoft's ancient MPEG-4 codec so my guess is your app re-encoded it, sounds like SUPREME quality right there. On a more helpful note, ffmpeg can decode all Microsoft MPEG-4 variants so ffms2 will do the job for you.

No shit. Youtube uses FLV. In case you find me a good way to turn flv into lossless, go ahead.

Good enough for what I wanna do with it.

Alright, got ffms2 and ran the .exe. But it won't let me use ffmpegsource as valid option. What do I have to do? (It's been a while since I last used/updated my avisynth)

ffvideosource("video.mp4")

Won't have audio. If you want video and audio, use this instead:

ffcopyrightinfringement("video.mp4")

I'm sorry, I just like that name too much lol.

Nice table of what formats/containers YouTube uses:
http://en.wikipedia.org/wiki/YouTube#Quality_and_codecs

And if you want audio follow this: (taken from the manual/read me)

A = FFAudioSource(X)
V = FFVideoSource(X)
AudioDub(V, A)

or use FFIndex().

FFIndex(X)
AudioDub(FFVideoSource(X), FFAudioSource(X))

X = your source
Insert clever text/image here.
