I need to rotate a MP4 video by 90 degrees. There is software like Free Video Flip and Rotate available that does this but produces an AVI file. Do you have any suggestions for a software to produce a MP4 that is in the same quality (and file size) as the original, just 90 degrees rotated? Does not have to be free software ;-) | ||||

There's no way to rotate a video without re-encoding it. So you can only appoximate the size and quality. I recommend VirtualDub to do the rotation. It's free and fast. | |||

I used Avidemux, a free video editor. This software allows you to rotate any movie. In a drop-down list you can select the desired output format (e.g. MP4, AVI, FLV, etc.). If using the MPEG-4 ASP setting in the video drop-down list, you will have to fiddle around with Quantizer setting (A higher number means reduced file size and less quality). This tool is great when you capture a movie on your cell phone and want to send the movie to friends! | |||

The easiest method I've seen is with QuickTime (Pro), open Movie Properties, click Video Track, then go to Visual Settings and use the arrows to rotate as needed. Then close the Movie Properties, then do a File Save As. | |||

Virtual Dub does not work with MP4 files and if Avidemux rotates video, how? I've been messing around with it and see no way to do so. | |||
