Convert m2ts on OSX
Last year at SymfonyCamp I made some video recordings with a borrowed camera. About 1.5 or 2 months ago I received the DVD's with the raw material on them. The raw material, however, was in Sony's proprietary m2ts format, something at least Adobe Premiere can not open. After an evening of googling, the answer turned out to be closer than I thought.
Searching for something like 'm2ts convert OSX' gives you a lot of results. However, a lot are quite useless, for instance torrent sites and such. However, there are some discussion forums in the results where solutions like ffmpegx are being mentioned. I am afraid I couldn't get the ffmpegx conversion solution working. It did convert the movies, but the resulting movies were mostly noise and not much of the original image.
The discussion forums also mentioned some other tools, some of which - as was commented, used libraries that were from iMovie. People on these forums wondered why iMovie didn't support the m2ts format.
I decided to start iMovie anyway. When iMovie was running, all of a sudden it recognized the DVD I had in my DVD player as a "camera" and listed all the available movies on the camera. It was my lucky day. As it turns out, iMovie is easily able to simply import the movies if it sees the DVD with the video's as a camera.
The resulting movies are of excellent quality and definitely usable for video. I'll use iMovie to export to a format Premiere will accept and edit in Premiere, as I for some reason can't get used to the iMovie'08 editting interface.

Evert: I suspect .m2ts simply means Mpeg-2 with a transport-stream format.
I'm surprised FFMpeg didn't work! I would suggest also trying VLC in the future (it has an export wizard).

Jason: What version of iMovie were you using? How did you import the files from the DVD? The DVD was inserted into your computer's built-in DVD drive?
I ask because I can't get it to work. I burned my m2ts files to a DVD but can't find a way to get them straight into iMovie.

Jason: Oops! You already said you were using iMovie '08. I should've picked up on that.
Still can't figure out how to get the DVD to be recognized by my iMovie '08, though.
left: Hi Jason,
For me it just worked for some reason. I could just import the files. You could try simply doing drag and drop from Finder to iMovie, perhaps that will work for you.

Jason Garber: Okay, thanks!
Gregory Tipton: I am working with the m2ts format for the first time. As I had hoped, the files that remained on the client's camera are readily readable and convertable by iMovie '08.
But now, I am also faced with another set of files that were removed from the camera at an earlier date on a Windows-based PC. The files are, so far, unreadable by QuickTime, MPEG Streamclip and the like. I can view them via VLC, but cannot convert from VLC so far.
Did it ever work for you Jason?

Jason: Well, I eventually got conversion through command line programs working, but the audio & video wasn't synchronized. Then I realized that HandBrake would convert them. I've used HandBrake for years, but never thought about applying it to M2TS files. It worked beautifully.
