CUDA *on* for AVC- EXPORT- very slow on my system

[Tyrone Braithwaite]

I've just been dumping off some rushes on my windows based Core - i7 system and was disturbed it was taking 14 mins to ouput a 1min 1080p/25 AVC file.

Why? I'm sure CS4 was never this slow? (Made sure max render bit depth was turned off etc.)

So I did several tests out of the 5 exports (four with CUDA Hardware on) were 14 mins and the one with cuda off was 3 mins.

Draw your own comparisons, and mine is a CUDA hacked card but establishing fast output to me is critical.

forwarding this to our Cuda god.. Might already be fixed in house....

Cuda guys asks for following info:

1. AVC-HD or AVC-Intra?
2. Direct export or Queued to AME?
3. Can we have a test file or test project?
4. What are your export settings?

Cheers

1. AVC-HD
2. FILE - EXPORT - MEDIA (CS5) (only way I know)
3. OUTPUT for PAL Blu-ray:
PAL: 1920x1080, 25fps, Upper Field, 25mbps - CBR
Profile: High Level 4.1
AUDIO: PCM
4. Where do I send?

(I'm producing 25fps blu-ray which means I can only access 1080i for output, not that it should make a difference.)

thanks.

Just tried AVC-I, same result - 2-3 times slower.

Another (positive observation) the output overlay/vmr is much better quality with CUDA turned on. And 4K Processor utilization drops from 90% to about 60% too.
