Update on SVRT = Works
I've updated the first post after some more testing and with the B frame corruption issue now fixed, I had a look at SVRT again and I'm happy to report that this too now works correctly:
1) Speed - Part 1: Compared to CPU Rendering, SVRT can take as little as 40% of the time but this will depend on the size of your clips and % that needs to be rendered (see Note 1 and 3). It is clearly slower than just copying or remuxing (as this would take only a few seconds) but it is a great potential seed improvement
1) Speed - Part 2: The next test was to add sample Title and Clip Transitions and PD11 be behaved perfectly by only dropping out of SVRT to CPU render just these required components. The result was that the time taken to produce the file only increased marginally for each of these (see Note 2).
2) Quality: I have seen no quality issues that plagued earlier versions of PD. There were no artefacts or Audio/Video Sync issue on the transition point in the produced video (even after remuxing).
Overall - I'm very happy that 1080/50p (or 60) support in PD11 looks as come of age with:
- 50/60 Tic Timeline
- High quality CPU and SVRT Rendering
....now of the muxing was a bit more std it would increase compatibility with 3rd party devices.

Note 1: Test was one 2:20 sec clip with no transitions, titles etc which (on my PC) took 1:38sec to CPU render and 0:39sec to SVRT.
Note 2: Test was two of the 2:20 sec clips back to back. With no title or transitions it took 1:13sec to SVRT, 1:19 with a single 5sec title, and 1:25 with the title and a overlap fade between the two clips.
Note 3: I did a test of an Hour Long project with many short clips, lots of titles, transitions (even other format material) and SVRT was 13% Slower in rendering the output vs CPU.
Note 4: I did another test with a mix of clips, transitions and titles. Again SVRT was slower than CPU rendering.
