Edius 6.5 recognized my JVC TD1's AVCHD 3D files weeks ago. I believe the support Grass Valley has added is in the form of AVCHD 3D file export. Edius now lets you export 3D video as 60i m2ts files (up to VBR at 26mbps max). In my limited testing, however, the usefulness is questionable. PowerDirector 11 sees the Edius m2ts files as 3D, and it allows you to write AVCHD 3D folders to an SDHC card from the timeline. These files can then be burned to a Blu-ray disc for playback on an AVCHD 3D compatible player (like my Panasonic 320). This works. Unfortunately, the video has nasty artifacts when there is any motion, or even a simple dissolve. PowerDirector 11 re-compresses the AVCHD 3D footage, and IMO the resulting image quality is unacceptable. What use is PD11's creation of such AVCHD 3D folders if the original quality is not maintained? I see exactly the same artifacting in a Sony TD10 video created by PD11 (sent to me by a fellow AVSer). Finally, unless I'm missing something, Edius can't burn these 60i m2ts 3D files to an AVCHD 3D disc. It burns only 2D discs.
The other test I did tonight was in Vegas. Unfortunately, Vegas sees the Edius 3D m2ts video as 2D only. It was exactly the same file that PD11 recognized as 3D in the first test. Once again, the AVCHD 3D "standard" seems to be anything but standard to these various software packages.
On the positive side, the quality of the Edius 3D m2ts file is very good. If only there were some way to play it! PowerDVD 12 plays back such 3D files at 24p, not 60i, so motion is choppy. And there doesn't seem to be any way of getting this AVCHD 3D video onto a disc without re-compression. If I'm mistaken about any of this, I'd love to hear it.
So, my workflow remains unchanged for 60i 3D projects: I edit in Edius and then export the video in a format Vegas understands (Canopus HQX, MPEG2, interlaced). I then let Vegas do the de-interlacing and create a standard 24p Blu-ray 3D iso. In my experience, Vegas is far superior to PowerDirector for de-interlacing. Going forward, I'll be shooting serious subject matter in 24p to eliminate the nightmarish problems caused by interlaced video. For some casual stuff, like family events, I may shoot in 60i for the better motion handling, but I'll use the free MediaBrowser software that comes with the JVC to edit such footage. It's ultra simple, but it doesn't re-compress the video at all. It lets you burn an AVCHD 3D disc whose 60i 3D video looks identical to the original footage (except for simple dissolves or titles, and these don't seem to cause any noticeable image degradation).
