MP4 Rotation Property

[JMFord]

I have some videos that have an incorrect rotation property. This means that some viewers will rotate it and some will not.

I am looking for a utility that can update the rotation property so that the video will not be rotated.

I believe that FFmpeg can do it, but I really don't want to slog through the doc to determine how to flip a simple bit. I would also prefer some method that can do this in place, but at the moment any solution is better than what I have.

Thanks, everyone.

Maybe quicktime pro. Or it might only be for mov files.

Thanks, but I was hoping for something free and I'm not going to lay out funds for "maybe" it works.

I also should have mentioned that I would prefer Windows XP compatible software.

I don't need anything fancy. A simple command line utility to set this property to zero would suffice.

Googling "rotate ffmpeg" isn't really a huge slog. Good luck.

Maybe remux with My Mp4Box GUI. Or MP4 Muxer. Or Mp4Box.
