Speeding Up Final Cut Render Times
Ok, so we’ve just started editing in HD and I have to say the render times seem to be incredibly long. Just to give you an example, doing a 5 second clip with color smoothing, chromakeyer, spill suppressor and color correction with a bkg underneath takes about four minutes 20 seconds to render. The first thing I have done to speed things up is to set it to render half res since we’re doing 1080i this still looks quite good and is more than adequate for web previews and I only have to render after we have approval from the client. This cuts the time down to about 52 seconds. Still slow but much more reasonable. The second thing, and this is what my question is about is both 8bit and 10bit YUV take the same amount of time but when I switch to RGB rendering the time to render is cut in half down to 26 seconds. I realize it’s a totally different color space. My question is this. Could I render in RGB Half Res and then when it’s time to export the video do Full Res and render with YUV 10bit high precision? My worry is that my effects would then be off some which then begs the question, do I just keep it in RGB when I export. What is everyone’s thought on this?
Oh, my system specs are: Mac Pro with Kona LHe Card, 8 core 3GHZ with 5GB of RAM

My thought: Never render as you work. Just step through your effect, then move along to the next task. When you walk away for lunch or the end of the day, start your render.
Editors have a tendency to render as they go.
Motion Graphics Artists have a tendency to step through effects and render when they walk away.My advice: emulate the motion graphics workflow. It’s hard to get used to it but really the way to go.

That’s what I do, unless there’s a client that needs to see it rendered.
I’m usually satisfied with previews, still frames & scrubbing through to get an idea of the final product. Once I’ve got the edit close to locked down I’ll start rendering.
