I just bought a Samsung Camcorder (SMX-F30BP). It has the ability to capture in standard Aspect Ratio (I guess 4:3) or in 16:9 format. The problem is that the mp4 (H.264) file generated is always regarded as a 4:3 format in any player I tried (media player, MPlayer, VLC, etc.), despite the fact that the frames are actually 16:9. Only by manually setting the Aspect Ratio to 16:9 in the player, I get the movie right. Does someone has a clue on what is going on? Is it a bug in the cam software? Is there something I can do? Thank you for your answers.
There is simple way to correct spect ratio without re-encoding.
"E:\Program Files\Yamb\mp4box.exe" -par 1=64:45 %1
IF [%1]== GOTO END
You can modify the aspect ratio without re-encoding.
EDIT : For MP4 files see this article:
See MPEG4 Modifier
The MPEG4-Modifier does only work for DIVX encoded files. For H264-encoded videos you could try to use the H264 Apect Ratio Modifier (H264ARM) from this thread:
It works without reencoding but patches the values in the h264-stream instead.
