comment Tool to transcode Canon PF24 MTS files to native 24p?
Thanks for your answer, I will give it a try, though unfortunately it seems this tool does not read .mts files but QuickTime files, which will add an additional step to the process. But if it works well, I guess I'll live with it!

comment Exam Question - end-to-end delay from video capture to video playout
You are not considering reordering of MPEG frames, I think.

comment What is a good efficient way to isolate clips from long movies?
The documentation for ffmpeg is at ffmpeg.org/ffmpeg.html. It looks like you should put the -ss option before the -i as that does a direct seek into the start position. The format of -ss and -t can be in seconds or hh:mm:ss.xxx.

comment Does the M4V file type have direct support for Audio?
No problem. Guess what, this is NOT a container file, you have a raw H.264 elementary stream. Your vendor was right, that file format cannot hold audio. You may want to suggest that they use a different extension for these files, I've seen .avc and .h264 used for this format. Also, you may be able to generate a .mp4 from he m4v and the aac using ffmpeg, if ffmpeg is smart enough to recognize the m4v file as an elementary stream.

Download the XVI32 hex editor from chmaas.handshake.de/delphi/freeware/xvi32/xvi32.htm#download. Then unzip to any folder (it does not come with an installer). Then double click XVI32.exe, select File|Open and then choose one of your .m4v files. Take a screenshot of the application window and paste it on your question. I'll take a look and tell you what it is.

Are you on Windows, Mac or Linux? I can give you specific instructions for your OS to inspect the file if you want.
