Thanks.

I think it would be useful if you gave a little more information about what you're trying to do; you see, M2TS isn't a codec, it's a container format, so although what's inside is probably MPEG2, it could also be AVCHD or whatever Blu-Ray is, or something else. And you can't really convert losslessly, unless you want to take your MPEG2 stream and mux it into a different container unchanged. Yep, we definitely need more info before we can help... where are you coming from, and where do you want to go?

I transferred the Video I shot with my HD camcorder, to my computer.  The file on the comp. is M2TS.  How can I convert that to MP4 or .MOV?  Should I mux or demux that file?

Thanks.

Thanks!  I'll give that a shot.  I probably shouldn't be posting about non Canon T2i subjects.  Sorry.  Just venturing out now to HD video!   :D   Still need to test drive the HD video on my T2i!  Lot's to do and what a great hobby!  I am NOT bored!   8)

I don't think we're strict about "non T2i subjects", many of us have upgraded since we joined, and/or share things we've taken with our "other" camera... the only thing I would say is, be clear if you're posting a photo or asking for help (which you did) because people will assume. We're a friendly bunch  ;)

I'd also be interested in a review of MPEG streamclip - if 1074 recommends it I have high hopes. Personally I like to use FFmpeg because I like command-line, but that's not for everyone. A free solution that is more user-friendly should be more popular. Super(C) was another solution, but I don't like promoting them because they've trampled on the open-source licence terms, and incorporated FFmpeg code into a commercial product.

I like MPEG Streamclip mainly because it's cross-platform, easy to use, works with practically every codec out there, and converts fast!

I use it at work quite a bit, my department edits in Final Cut Pro on Macs, but other departments (and our main video server) run in Avid on PCs. For several of the shows we produce I shoot and edit on Mac, but it has to go through the Avid system to get to air. With MPEG Streamclip I can output an .MOV from Final Cut, transcode to one of the Avid codecs, and I'm done!

(don't tell anyone, but our commercial work still goes to BETA tape before airing...  :o sadly we have not transitioned to HD broadcasting yet. :'( )

Thats pretty funny.
I interned at a production company in high school (2007) and I remember they had a client in a SUPER small market that wanted their commercial in HD. They said ok, but the producer didnt spend the extra expense on HD cause he knew they wouldnt have it their market for another 4+ years. So he charged them HD for SD. No one noticed.
"Wow, that camera takes nice pictures!"

I get asked by ad agencies fairly often for our video delivery specs, and answering without giggling to myself a little bit is difficult. They get wrapped up in codec confusion, and not wanting to compress (recently I was ftp'd 3 :30 commercials in PRORES.  :o ).

I just tell them I'm converting it anyway, so "just send what you have, and make it small."

 ;D
