When I transcode the original 1440x1080/60i M2TS file to a 1280x720 mpeg4 file the file size increases. Examples:
one.M2TS 20,823 KB
one.avi 39,471 KB
720p mpeg4 is 189.6% of original file size
two.M2TS 85,242 KB
two.avi 186,710 KB
720p mpeg4 is 219.0% of original file size
three.M2TS 80,298 KB
three.avi 154,400 KB
720p mpeg4 is 192.3% of original file size
four.M2TS 13,632 KB
four.avi 23,161 KB
720p mpeg4 is 169.9% of original file size
Is M2TS support planned any time soon?
Andrew Pile Staff
It's not planned, no.

T-Rav, the filesize increases because you don't know how to export correctly in AVI. You are using lossless codecs or something that require more bitrate than AVCHD. Read the sticky thread on the Technical Help forum to learn how to export correctly.
Vimeo does not support AVCHD codecs because their underlying software, ffmpeg, does not support it. There is an ffmpeg patch for AVCHD support, but it's not official yet.

Well actually, I am using ffmpeg (version SVN-r11870 for windows) to convert to AVI. Here's the command line string:
ffmpeg -r 29.97 -s 1440x1080 -i four.M2TS -vcodec mpeg4 -sameq -acodec copy -deinterlace -aspect 16:9 -s hd720 four.avi
I'll check the sticky to see if there's anything in there that I'm missing about AVCHD. Thanks.

This seemed to work the best for me:

Canon's HD cameras has .m2ts files/AVCHD.. too bad a HD video site doesn't support the bigger HD brands out there :)

Those are the files used on the camcorder. You should export the files from your camcorder onto your computer using one of the many video editing programs available which will convert it into a usable file.

...And vimeo can't convert those to make the process easy?! (The other video *tube does it?)

It's a matter of universal video standards and compression sizes. We may do it sometime in the future, but it's not on our list right now, sorry.

wanted to bump this back up hoping to get a little attention
i just bought the Canon HF10 and i;m kind of taken back that, at least by now, vimeo has not included .m2ts files
.m2ts files are not going away so it would make since to include
please, PLEASE make it so
thanks

YouTube and Google Video supports direct .m2ts upload but greatly compromises on quality.

Another hopeful for .m2ts upload support.

It won't happen any time soon. Vimeo uses ffmpeg to decode uploaded files, and ffmpeg simply does not support AVCHD correctly. Some files are recognized, others don't, others are completely buggered up. Avoid. Learn to encode properly with your video editor, and don't waste bandwidth for either yourself, or Vimeo.

My HDSR11 does the same output m2ts and it's a pain to convert.
Eugenia Loli Plus
No, it's not a pain to convert. Get a video editor, use the supplied tutorials on vimeo, and you are good to go.

A simple fix for converting M2TS files from Canon to format acceptable to vimeo:
Import the file into Picasa, select the video, and hit "Export Clip" {no need to "reset start and end"} which then converts the entire file into an WMV file which can then be uploaded to Vimeo.

What video editor is best to use in order to convert M2TS files?
Eugenia Loli Plus
Vegas Platinum 9 works fine with AVCHD.
Bryan Sellars
As does Corel Video Studio Pro X2 it has a proxy editing system to take the strain of the processor, and has HDV 720P (1280x720) output that is fine for uploading to Vimeo
Alex Stone Plus
The reason your AVCHD file is bigger when exported to any other format is because AVCHD is *HIGHLY* compressed (that's how they fit so much HD content on a tiny 30/60GB drive)

I don't understand the comments on wasting bandwidth uploading files using the latest video compression standard! If you're not doing any editing on a file it would be nice to just upload to Vimeo as is, as other sites are able to do. Re-encoding files takes time and effort even if you know what you are doing.
Having said that I encode my Canon HF100 files using Windows Movie Maker's 720HD profile with pretty decent results.
