Converting MP4

[[Mike of the Desert]]

Hi Guys, I need your help, I can't find a way to convert a Mp4 file to any other.
I don't mind too much about quality this time, I just need it fast, and since Avisynth gives me a lot of errors if I try to DirectShow it, I really don't know what to do. ;\

Any idea?

I don't really know any other way around it,but about AviSynth errors... Can you please discribe those errors? (inserting here those lines would really help...) I've had quite a lot problems myself when I was trying out AviSynth,but I've learned to fix 'em,so maybe I'll be able to help you with yours too.

It would be great.. The problem is that when I try to run the scrypt (done by one single line of text) it says 'Evaluate: Unrecognized Exception!'

'Evaluate: Unrecognized Exception!'

Hmm.. That looks familiar..

Script please?

Damn,I just keep forgetting there is no edit button here

AviSynth,VDubMod and AMVApp versions?

You could always try FFmpegSource (you'll want version 1.9 in order to avoid the stack overflow error):
http://forum.doom9.org/showthread.php?t=127037
(put FFmpegSource.dll in AviSynth's plugins folder, and everything else in C:\WINDOWS\system32, overwriting any duplicates that occur)

It seems to work perfectly fine with MP4 files, and according to the thread, it's frame accurate - something DirectShow can't claim (plus it doesn't produce those grey frames at the end of the video like DirectShowSource does). Audio is turned off by default, so you'll need to write the script like this if you want audio:

Code: Select all

FFmpegSource("video.mp4",atrack=-1)

Just hope that the file doesn't have a variable frame rate, as there's nothing in the development thread to suggest that it maintains audio sync with VFR (only that it uses average framerate, but that means shit when trying to convert the thing to CFR and maintain absolute sync - for that, DirectShowSource's convertfps function still excels). Note I'm basing this on assumption due to what was actually said there - I have very few VFR files, and all the ones I'm aware of that were VFR were WMVs, not MP4s.

Thanks. ^^
So.. I have to disinstall AviSynth and go searching the older version?
k, I'll try that.

No, that's version 1.9 of FFmpegSource, not AviSynth. It's meant for the current version of AviSynth (the 2.5 series, which is included in the AMVapp).

Got it, thanks. ^-^''
