As far as maximum Render Quality, it won't make that big of a differendce if you are starting with HD material and exporting to the same frame size.
It does make a difference when going from HD (1440x1080) down to 720x480 SD. It is better than CS3, but not as good as Dan Issacs method of downscaling.
>If my project contains high-bit-depth assets
>I'm capturing HDV
Those two statements are contradictory.
HDV by definition is only 8 bit per channel.
Thanks for your response in regard to my question on Maximum Render Quality. Sounds like I will not benefit from selecting Maximum Render Quality before capturing with my Canon HV20 HDV Camcorder and posting to Blu-ray maintaining 1440x1080.
Jim and Harm,
So I am capturing High-Bit-Depth with my Canon HV20 HDV Camcorder? Is there any benefit to selecting Maximum Bit Depth than? If not who benefits from this option? I've got a big project coming and I want the Blu-ray to look as close to the original HDV material as possible.
Thanks so much!

No you're not. That's what we're saying. HDV is only 8 bit. Typically the higher bit depths come into play with higher end media, like if you capture from HD-SDI.
Thanks for the clarification.
Just some details that i find useful on maximum render depth
You really need it even with 8bit source files, when using heavy grading/multiple curves/vignettes. If after grading you see banding, go to sequence > sequence settings from the top menu and check "maximum bit depth (ignore the performance popup), then check again your preview (it will change in a second) to see if banding is still present in 32bit mode. If no banding, you must check it when exporting, if banding is still there, change your grading, then uncheck it to continue with editing.
Unfortunately Maximum bit depth exporting is extremely time-consuming, but can really SAVE YOUR DAY when facing artifacts after heavy grading, by completely or almost completely eliminating banding and other unwanted color distortions.
Use it only for either small previews or the really final output.
