1080 Color Correction
Another question: I have a new 64 bit Raid 0 computer, with Intel core i7 930, 280 GHz quad core (but just the two Raid 0 drives). Still experimenting with everything. I’ve a little Kodak video camera (like a Flip–just to learn what I’m doing before a major investment), which shoots in 1080 and 720. Both run smoothly in Prpro, without rendering, thanks to CS5 engine. But in 1080p, when I try something like change to color color correction, I get tremendous artifacts in the picture–looks like TV 50 years ago (yes, I do remember that). Rendering didn’t improve it much. Any thoughts? Is this a computer problem; is it due to my lack of an extra media drive, etc?

I only know CS4, but perhaps this helps: right click on your preview, and set quality to highest. Usually, rendering should have helped, but you could give it a try.

What kind of correction are you using and how far are you pushing it? Any compressed format (like the one you are editing) is going to start artifacting pretty badly when you push colors/luma etc. too far out of what was recorded. The artifacts you are seeing are always there, my guess is that you are just bringing them out.

I recently tried CS5 and found that my AVCHD footage looked terrible in the Preview monitor, all sorts of compression blocks. Now one would think that reducing the monitor resolution would make it easier for the computer to play back the video, but in reality, I had to right-click the monitor and change the resolution to FULL quality and it resolved the issue, so check the resolution

Well, I’m probably pushing too hard, just in the testing mode. The artifacts are about 1000x greater than in the original though, as I see none there.
Thanks

No, Monitor is at full Res: it’s not a monitor thing, but may be a video card thing?

Another test, render out a final of a couple seconds of the worst footage and see if it occurs there. It might also be from the compression/decompression on the fly you are trying to do from the timeline or monitor.

Neither rendering on the timeline or after exporting to a HD did it. But by trying a less taxing color correction, Fast Color Correction, instead of Change to Color, there was no problem, even without rendering!!

It was on full in the Program Monitor (:. But see below.
