Help Needed. Weird video conversion results h.264 video .ts file to .mov
So I have an odd video (concert) file that has a h.264 video stream (main profile 3.1) with ~256kbs AAC audio, but in a .ts container.
I tried to do a pass-thru of video and audio from .ts container to .mp4/m4v
I tried iFlicks, IVI, iFFMPEG, MP4Tools, and I think Subler.
Non of these worked.
Surprisingly, QuickTime X actually was able to export to a .mov file. It only took about 1 minute on a quad core Mac mini, therefore I don't think QuickTime altered the video or audio.
Now the weird part. The original .ts file is around 830 MB and the new (assuming pass-thru) .mov file is around 780 MB. The concert is around 52 minutes.
Anybody know why a there is a 50 MB difference in file size? Is there that much overhead info in a .ts MPEG-2 container file VS a .mov container?
I also checked both files in iMediaHUD (MediaInfo type app) which said the audio was the same but the data rates of the video were different. Could this be the extra container overhead info in a .ts file?
Just to confuse myself more, neither to the video files hit the iMediaHUD video data rate when observing in VLC codec details.
I just want a "pure" version of the file in an Apple device friendly container, and I'm curious about the file size differences.
Dynaflash or anyone else have an tech info?

It can't, in addition to the above, store, with gps / compass-enabled cameras, dynamically changing location / direction info in a standardized way (it uses non-standardized, embedded plain sub / text files - pretty ugly if you ask me). In this regard, AVCHD's (M)TS files (assuming they store the location info and not external .ply files) are also far superior.
This is why it has a sizable overhead over the "static" mp4 container.
