Video playback causing CPU spikes

[Tripi]

Has anyone noticed in 8.06 that some videos cause spikes in the performance, which (in my case) results in clicks and pops? I'm using Vienna Pro, and it is certainly a big template, but not something my computer can't handle. If I take the video out, the performance meter goes way down. Has anyone found the most optimized video settings for DP8? I know we've gone over this in the past, but I have been out of the loop for a bit.

thanks!

Maybe I should ask it a different way: Has anyone tried using any of MOTU's video boxes to handle video playback? I want to keep the video on my computer in my DP screenset. If I use something like the HD Express box, will it take the processing / codec decoding heavy lifting off of my computer's processor, and still display it as usual?

Tripi, are you running the video from a unique drive? Also, I've been running QT h.264. Also, I ran video from a RAM disk and it' divert smooth. I use Make RAM disk. Leave originals somewhere safe, of course.

Thanks for the ideas. I do run video from a dedicated video drive (over FW), and it is H264. I didn't consider the ram disk option yet. Charlie offered to let me come over and see that video slave software in action, so I can look in to that too. Just never been the same since DP8 re-wrote the video engine. Wish this wasn't such a time suck trouble shooting it.

You could try making them prores - bigger files but less processing needed. I'm running prores off of the internal SSD & no playback issues

[Tripi]

I haven't seen that suggested before. Is prores a codec? (Pro-Res?)

thanks!

DP8's video engine is incompatible with older video cards. I had to upgrade my card from the stock 256mb NVIDIA to run video with DP8. Any video whatsoever was causing spikes and system wide slow-down until I got a newer card. I think your machine is newer than mine (you're able to run 10.8.x, which I can not), but it's something to look into.
