Mercury Playback Engine + AVCHD
Hi Folks — As you can tell from my sig file, I have a PC with pretty decent specs for 2011. I am able to edit 1080 and 720 AVCCAM files pretty easily.
However, the process isn’t as smooth with Premiere CS5 as it is with my copy of Sony Vegas 10.
For starters, I need to render everything I put on the timeline. I set up the project according to the specs I shot with yet I still need to render. Then there is always a lag from when I press play to when the file starts. On Vegas, I can throw any files on the timeline and they all play with zero lag.
I have some plugins for Premiere that I really love and would love to use it as my main editor — it also feels a bit more ‘natural’ to me than Vegas.
So, is this performance normal? Will the Mercury Engine not work for me because I have an ATI card? Do you all have to render your HD clips when dropping them on the timeline? I just want to know if my experience is the norm or the exception. THANKS!

Hi Edan,
The Hardware Mercury Engine will only work with higher end Nvidia cards as listed on the Adobe site.

Actually, if you edit the cuda_supported_cards.txt appropriately you can use many other Nvidia cards that have CUDA Cores. My inexpensive GT 240 card has 96 CUDA cores and 1GB of DDR5 memory and seems to work perfectly fine with CS5. Previews are generated about four times faster than without on a six core AMD machine.
If you are going to try an inexpensive card, do make sure that you get a card with DDR5 memory and more than 786MB of RAM (just get a 1GB or better card) if you want to see a performance improvement.
