After downloading the PPro CS6 trial version i have tested the warp effect with the following result:
Clip: 350 frames
Size: 1920 x 1080
Warp effect: smooth motion and (no motion, didn't work)
Core i2600, 4 CPU
16 GB Ram
NVIDIA GTX 570 (CUDA supported)
The creation of the warp effect takes 4 minutes and 20 sec. > unusable.
I load the same clip into my PPro CS5.5 with ProDAD's 64Bit Mercalli V2 Pro stabilizer plug in installed.
The creation of the warp effect takes 25 sec!
I can't understand why PPro CS6 takes so long time. I hope and i expect this issue will be fixed soon so i can upgrade to v6.
If you think it is an issue, file a bug on the usability / performance aspect of it -- the fact it takes so long
