How to correct aspect ratio I have a movie in AVI format from a toy helicopter that reports an corrupt or missing index but still plays in VLC very wide and short.  When I click Video -> Aspect Ratio -> 4:3 the file plays as it should, but I have to do this each time I open a file.

Video file info: Video: mjpeg, yuvj422p, 720x240, 59.94 fps, 59.94 tbr, 60 tbn

The video dimensions are 720x240 and according to the instructions the video should be 720x480

I am looking for suggestions for video conversion software that will allow me to change the aspect ratio.  I am using a Mac, but have access to Windows PC as well.  Freeware is preferred.

I have tried Handbrake 0.9.9 on Mac, but I can't seem to find a method of increasing the vertical size beyond the original 240.
FFMpeg has an option to modify the aspect ratio of a video file without actually modifying the video, see http://www.ffmpeg.org/ffmpeg-all.html#Video-Options

For example, in your case, the desired aspect ratio is 720 / 480 = 1.5 (3:2) (which is NOT 4:3, it should be 540 in that case)

So your command line may look like:

ffmpeg -i input_file.avi -c copy -aspect 1.5 output_file.avi


This copies both audio and video streams unchanged to the output file, and specify into the file's metadata that the aspect ratio is 1.5 as a hint for video players.
