Conversion from mp4 to avi leaves widescreen image compressed to 4:3.

[Jim Carls]

I'm converting an mp4 file taken from a Snappy-type camera to an "MS
compatible AVI" file with WinFF 1.4.0. The conversion seems to work,
but the original widescreen image winds up compressed horizontally. I
tried entering "16:9" in the aspect ration option, but the resulting
file had audio only with no image (although the size of the file
suggested it contained video). I'm trying to convert because my
Premier Elements 3.02 says the mp4 file is "corrupted / component not
installed."

One odd thing is that the original mp4 file will play fine in Windows
Media Player, but if I select "Play" within WinFF, it appears and the
audio plays, but the image does not move unless I click within the
image, but it only skips to the "current" location in the stream and
freezes again at that point.

Any suggestions? Thanks!

For us to help, could you give us:
- The FULL copy of output generated by ffmpeg when using winff to
convert your file. To get that, start winff -> Options -> "Pause on
Finish". You will see a terminal screen with output, please copy/paste.

- The output of ffprobe on your source file and a resulting file? Run
ffprobe in a terminal like:
ffprobe ~/path/to/file

Well, you didn't say which OS you are running on, and in Linux
distributions ffmpeg usually comes with ffprobe. If you don't have it,
just run ffmpeg without any arguments on your file, the output is nearly
the same.

Why not? There really should be a way to do that.

I have no idea how to do this on Windows.

I think you should replace the semi-colon ":" with a space " ".

Please try again.
