Yeah, but it's just a driver thing. There's no reason a 8800 geforce couldn't be able to technically perform all those little tricks. If memory bandwidth is the be-all-end-all then the 8800 series has something going on as the gtx has about 86.4 gb/s. Compared to the highest quadro fx 5500 which has about 33.6 gb/s.

But ofcourse memory bandwidth doesn't correlate to "business" performance whatever that is. Video editing doesn't really utilise those specific opengl calls anyway. They are for 3d-work.

So Joe and I got together last night to do some HDV testing on the new crazy fast PC and some HDV footage...

Here are some results:

We dropped two video clips 1440 x 1080 60i 29.97 fps similar in size to the Vegas 7 timeline. One clip was captured directly to the hard drive in the M2T format using Vegas. The second clip was captured with a trial version of Cineform (Prospect HD 1.5kpbs 24 bit 29.97).

Using the "Preview/Best" viewer setting:

Test One: Both files played perfectly on the timeline without any change in preview frame rate.

Test Two: Added yellow tint, brightness/contrast & glow filters. M2T played back at about 23fps average. The Cineform file much less at about 19fps average.

Conclusions is: WTF???

Isn't Cineform suppose to yield a 4X increase in performance? Anyone have any ideas we can try again?

Using NewTek's SpeedEdit on my core2duo 2.33 macbook pro 15" with the external display connected to a dell 24" 2407 monitor, I can do 2 streams of hdv with color correction and a DVE applied to the second one and a title overlay in real time monitoring at full resolution. :) I just love it :)
