As discussed in another thread the option for nVidia users to use Cuda or OpenCL for rendering and preview.

I just ran a small test using 5 x HD/Mov clips with fade transition for a total of 3.5 minutes rendered to m2ts(AVC)

Using OpenCL time was 2.50
Using Cuda time was 2.12

Final file size 450mb

I am using SLI so may differ on your times, openGl did seem smoother on preview but that could just be my imagination

Hi David,
Thank you for posting your information.

Only you can ask such probing questions :

Here you go direct from PD10 Properties for the clip

Type: H.264 AVC
Bitrate: 43.54Mbps
Resolution: 1920x1080
Frame rate: 25fps
Aspect Ratio: 16:9
Profile: Baseline Profile
Frame Type: Progressive

Audio:
Type: WAV
Sampling: 48kHz
Bitrate: 1536Kbps
Channel: Stereo

I hope that helps.
