Thanks. But in their MVC templates is the AVCHD that I used....

MVC rendering creates a pair of files which are main and dependent views. You need to import main view (*.avc) file info DVD Architect 6.0 project - it will load dependent view itself.

Also what I found out when worked with 60i to 24P conversion - I used Sony HDR-TD10 footage - then 2 step process creates better motion presentation. Two steps mean that you render left and right view to 24P separately and after that in a new project pairs the views and render it using MVC 1080/24p template. Resolution does not degradatre, but motion artifacts are much less if to compare with one step process when you render from time line directly to MVC.

"Resolution does not degradatre"

How?
When you convert interlaced to progressive (deinterlace)
there is always a little resolution loss. Especially at motion.

I will try this two step method, but what can be the explanation rendering worse video with 1 step method?

Resolution does not degradate means that visually sharpness of static objects looks the same after 1 and 2 steps processes. I say visually because I didn't make any objective measurements. But if to look at moving pedestrians and cars, motion artifacts after 2 step process are less noticeable. May be one step process when Vegas converts 60i to 24P and after it immediately encoding streams to main and dependent view uses less accurate algorithm then 2 algorithms in 2 steps process. It will be interesting - you will confirm my results or not.

Nsbma,
Is it possible to take an 1080/60i MVC file from the Sony HDR-TD30V, edit it in Vegas, render back to 1080/60i MVC, save it to an SD card and play the file back through the camera to a 3d tv? In other words, can I retain the highest quality after editing by bypassing blu ray altogether and play edited material natively through the camera? Can the camera read and play an edited 1080/60i 3d file or is this a no go?

GregFlowers,
MVC templates has only 24p for 1080. I believe that you can render left and right views separately in 1080/60i, render sound, but after it you need some software - not Vegas - to join views and sound back to Sony m2ts format. May be new version of free Stereo Movie Maker can do it? The key point here is to create Sony compatible files.

I think you would need an MVC encoder that encodes the footage to 1080 50i/60i - and that is not available in Vegas really. So there is no way to playback edited footage with the TD10, 20, 30.

More, I do not see what would be the advantage to do that. If you wish to maintain the footage in 1080 50i/60i, one way would be to render the footage to a multistream file and use the AVCHD 2.0 standard to create an AVCHD 2.0 BD - what can playback 1080 50i/60i footage with AVCHD 2.0 compatible 3D-BD-player. Unfortunately, that cannot be created with Vegas - here you need other tools like Edius that allows to render such files.

For 1080 60i user, the easier workflow is to render to 1080 24p directly. For 1080 50i user, the best possible way is to edit in 1080 50i, and stretch the footage with deinterlacing to 1080 24p. Of you use a camera like the Z10000 that shoots in 1080 24p in a direct way.
