Cutting down render time
System: Mac Pro 2 X 3.2 GHz Quad-Core Intel Xeon

ATI Radeon HD 2600 XT
4TB Rorke Galaxy HDX
Final Cut Pro 6.0.3So, we’re editing in uncompressed HD. A five minute, five video stream sequence takes 45 minutes to an hour to render. Is there any way of cutting down on this render time? Also is there any way to view the sequence, without having to render it after every change?

What are you rendering? I mean, you told us the format you are using, but what are you doing that requires a render? Adding a filter? Some filters require lots of processing, and some (FX Plug) also use the Graphics Card to speed up rendering. So a better graphics card would help.
But it would help to know what you are doing that requires you to render.

You can change your sequence settings to render at 8 bit. That will speed it up a bit. Once the program is final and you’re ready to master. Change your settings back to 10 bit and re-render. That’ll speed up your workflow at least. I use this process when editing at HD PRORES HQ and it’s almost a 3 to 1 render time ratio between the two settings.

[Dustin Park] “is there any way to view the sequence, without having to render it after every change?”
I’ll go a step farther than Shane and suggest that it sounds as if your timeline settings do not match your video source. Given the hardware you’re running, you should certainly be able to get enough realtime performance to keep from having to render every change.

To answer Shane’s question, the layers are as follows: video shot on green screen, graphic background created in Motion, graphic bug created in motion, graphic lower created in motion and graphic drop box created in motion, drop box contains either a .tiff or more video. The settings are different, but it brings up another question. The video is shot as DVCPRO HD and the graphics have an animation codec, the sequence finally is Apple Pro Res 422. Do they all have to match to ensure playback? Sorry, Avid editor new to FCP.

I can’t say for 100% certain, but I believe rendering Motion templates in Final Cut are EXTREMELY slow. Better to render them out from Motion as Animation + alpha and import into FCP.
Hopefully someone can back me up on that.

No wonder Dustin!!! You’ve got a render engine’s worst nightmare… Lots of very processor intensive elements and several different video sources that don’t match the timeline settings. Next time consider working in a timeling that matches the majority of the video footage, then you can switch the compressor settings to ProRes in Sequence settings before a final render. That will give you at least some realtime…

Aaron’s got it. If you are bring that motion project into FCP that’s where your hang up is.

I disagree slightly.
I import my Motion projects into FCP in order to SAVE time, not to waste it. But I am very picky about which ones. I always pre-render stuff that won’t change and that I know will be better handled by FCP as a movie. Some Motion projects need to come in as objects to complete timing adjustments or other tweaks.In this particular case:
1. video shot on green screen: Pre-render the foreground, import the movie.
2. graphic background created in Motion: Probably doesn’t matter but textures and stuff are best pre-prendered so they can be stored for future use, too.
3. graphic bug created in motion: Definielty pre-rendered.
4. graphic lower created in motion: Doesn’t really matter unless the text is also animated. Saving lower thirds as templates is a good idea so you can change names easily.
5. graphic drop box created in motion, drop box contains either a .tiff or more video: I’d do this as a live object,but that’s jsut me.bogiesan
This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

Hi Dustin,
If you need often to integrate graphics from Motion, AE, etc in FC, consider buying “Sheer”.
8/10b Uncompress YCbCr/RGB and always with Alpha channel available.
In the era of the 10b/YCbCr codecs, Animation (8b/RGB) is old-fashioned.Mac OX 10.5.2-FC 6.02-QT 7.4.1
