I'm surprised, too. During dissolves or moderate movement, the AVCHD 3D render (which is horribly, and uncharacteristically, slow) usually shows serious distortion (block like artifacts). Even highly detailed static shots sometimes shimmer and dance. OTOH, when I render to separate left/right mp4 streams from Edius, the files look much cleaner. (Such files also pair up just fine in Vegas.) The image degradation in Edius renders is very similar to what I'm seeing when I export AVCHD 3D to an SD card from PowerDirector 11. I also see the same problem in a disc that was sent to me by a Sony owner, who rendered his TD10 footage in PD11. In stark contrast, Vegas creates standard 24p Blu-ray 3D at the same bitrate, and it looks much, much better than the AVCHD 3D renders from Edius or PD11. Sure, there are some motion artifacts from the 60i to 24p conversion in Vegas, but the overall result is far better. That's why I say my workflow won't change. I have several export options from Edius that look much better than AVCHD 3D: high bitrate MPEG2, AVCHD (17mbps per stream mp4s), high bitrate Canopus HQ or HQX. All these options yield better results than AVCHD 3D renders. I'm especially curious to get your impressions of the AVCHD 3D renders from Pinnacle Studio 16. I'm hesitant to invest in it, because I'm afraid I'll get similar results. Since the trial doesn't recognize my 3D video, I risk buying yet another piece of software that does not yield acceptable AVCHD 3D renders. Please let me know what you think when you get a chance to do some tests in the Pinnacle software.
The exception for me to this AVCHD 3D "mess" is the MediaBrowser 3D software that JVC ships with the TD1. From native JVC files, MediaBrowser yields what I had hoped for from all this software - an edit that does not re-compress (and seriously degrade) the original footage. It copies the video exactly, without re-compressing and allows you to burn a great looking AVCHD 3D disc. Even with it, though, there seems to be a limit on the length the file can be. Long form programs won't be possible (not that I'd want to do a long form project with such primitive software).
Simply put, I'm extremely disappointed with these results. It makes me wonder if some severe limitations are being placed on these NLE makers, in terms of what they can and can't do with the AVCHD 3D "standard." Unless they're being handcuffed somehow, there's no way (at this bitrate) that AVCHD 3D should look this awful.
