region with YUV curve - buffer/processor limitation

[GrassValley_KH]

How big is the buffer, out of curiosity?

Core2Duo T7200 2GB ram using DVCproHD and SD progressive footage.

(No RAID but this appears to be a processing issue not a throughput -drive i but I could be wrong)

It works but runs out of buffer very quickly.

I tried that on a Core2Duo 6600 with 2Gb DDR2 and RAID0 Array...No problems with SD footage, no problems with HDV footage...no problems with DVCPRO HD footage...
What are your system's specs?

Edit with hidef all the time, works great - no realtime issues.

However when I use a region filter with a YUV curve placed outside of the region (creating a dark edged mask), the buffer runs out almost immediately.

This is on SD material also. So doesn't appear to be bottleneck based on HD throughput. Conclusion appears to be region is very processor intensive - but no more so with SD than HD.

Anyone willing to give the region/YUV a try and tell me your results?

My system is pretty fast in every other filter/transistion situation.

thanks
