Cineform for only HDV

For a system only editing HDV, do I really need Prospect HD 10bit or will 8 bit do.

I assume 10bit becuase I will do plenty of effects in AfterEffects and particleillusion. That correct? And it's best to capture into cineform at 1920x1080 right? (despite HDV being 1440x1080).

Does Cineform also improve speed when rendering in Premiere using plugins like MagicBullet's looks? is it faster than working with uncompressed frames.

Thank you members.

Color work benefits from 10-bit, and compositing can be easy with 1920x1080 square pixel -- too plus for Prospect HD. Capture to 1440 to 1920 up to you, although HDSDI/HMDI capture (naturally 1920) is better than tape capture if you have a live source.

We not accelerate rendering of the third party filters, but CineForm is generally faster than uncompressed work for many operations (not all.)

Would I need to set vegas to use 32-bit rather than 8-bit to take advantage of the 10-bit color in Cineform?

So I can capture my 1440 as 1920 and Cineform will take care of this form me?

I can then use square pixels... Hmmm. With non-square pixels in my test WMV, it looked fine when played on Windows, but on Linux, my player showed a squashed image.

Are there any disadvantages? Larger file sizes? Loss of detail?

I purchased the higher version because:

- My Windows computer is not that fast, and I wanted every advantage I could
get.

- I wanted 10-bits for color

- I thought that I might use some higher resolution images, even if they came from a different camera. The new memory card cameras are more popular now and I wanted to be able to easily mix the two video streams.

Vegas is still an 8-bit product for CineForm files currently. We want to support the new 32-bit modes, but higher priority projects have push that back.
