Converting .mov to .mts?

[UltraNEO*]

OK, I know this may sounds like a odd request but I'm in a bit of a pickle.

Is it possible to convert files which we're previously imported to iMovie as .mov back to their original format .mts, such as those created by AVCHD cameras? I'd prefer it if I can preserve as much quality, as possible.

If so, what plug-ins do i need?
It's for Premiere Pro v4

Thanks.

Can't help, or don't want to help?

Just from reading around, an AVCHD .mts is H.264 video and AC-3 audio stored in an MPEG-2 transport stream.

If, when iMovie imports it, it converts that to Apple Intermediate and uncompressed stereo, then what you basically have to do is re-encode into those compressed formats. H.264 encoders are easy to find, although you can definitely lose quality there; and you can probably find an AC-3 encoder.

Getting the results into a transport stream might be a problem. MPEG Streamclip can convert program streams into MPEG-2 transport streams, but only for content that it recognizes -- MPEG-1 or MPEG-2 video plus various flavors of audio, not H.264/AC-3.

Maybe if you explain why you need to do this, someone can offer another solution.

Hmmm..
Sorry, but is it really that difficult to explain how?
Without asking why?

Don't worry folks, I've solved it.

any solutions?

i also want to reclaim valuable hard disc space! my files are about 10X the native avchd (.mts) format.

will converting to MTS from MOV reduce the quality of the file? If I were to convert back and forth would the file be the same as the original MOV file or will quality reduce with each conversion?

It depends on what application you use with what settings. Since MTS files mostly use the H.264 codec and transcoding to a MOV file using the same codec, the loss will be almost nil, especially if you just remux.
