MP4Cam2AVI problem

[las7h0p3]

Hello all,

My problem in MP4Cam2AVI is that when I try to convert a mp4 file movie to avi movie the sound dosent match with the video ( the sound is showing 5sec after the video :\ ) can someone tell me how to fix it ?

Give us MORE information about your mp4. Use Mediainfo to identify all details, copy and paste it here.

But MP4Cam2AVI might not work with all mp4. You might wanna try something else like reconverting using WinFF, alltoavi, super, avidemux.

P.S. Is there another program for that information that can convert from mp4 to avi without loosing the quality and size of the file ? ( like mp4cam2avi ) ?

[las7h0p3]

Someone please ? ( sorry for my 2nd post ) I realy need to fix this problem. This is the only program that can get good quality... and the same file size.

Your video is variable frame rate (VFR) - that is why it is out of sync when you try to manipulate it.

AVI container doesn't support VFR, and it is only partially compatible with h264 video. But .mkv and .mp4 containers do support VFR - that's why you should leave it as is. Furthermore, AAC audio is not compatible in .avi container, therefore you would have to re-encode that.

Why do you want to put it into an .avi container?

It might be possible to fix it, but you would have to re-encode the video using a lower compression codec like xvid (=lose quality and bigger filesize), and re-encode the audio (=worse quality and bigger filesize). You might be able to do it with avisynth scripts to make it cfr and feed into any encoder:
DirectShowSource("PATH\file.mp4", fps=29.97, convertfps=true)

[Baldrick]

Why do you need an avi??? If you are going to edit it for example it's better to convert to avi with dv or huffyuv codec.


And please WAIT some days before you bump your topic next time.


edit: VFR is not support in avi as poisons says.

You might be able to do it with avisynth scripts to make it cfr and feed into any encoder:
DirectShowSource("PATH\file.mp4", fps=29.97, convertfps=true)

I never used scripts and I dont know how to work with them. :\

[45tripp]

it's simple enough.

install avisynth.

open notepad.
write:
DirectShowSource("moviename.mp4", fps=29.97, convertfps=true)
save as:
'movie.avs' under the same directory that your .mp4 file is.

from now on, treat 'movie.mp4' as your video file.
just drag it into vdub, set encoder,
encode.

[las7h0p3]

Thanks, works great. Btw Is there a way to tell the DirectShowSource what filesize I want ?

[45tripp]

umm no

filesize is dependent on encoder settings...
(unless you mean to trim the source that is)
so change the bitrate (or constant quant) in vdub to change filesize.

[las7h0p3]

But if I change the bit rate the quality will be bad. :\

Small bitrate -> small filesize -> bad quality

Big bitrate -> big filesize -> good quality

[45tripp]

such is life,
