Rendering with Chroma Key Filter

Posted by Nick Fullturn on March 31, 2011 at 7:49 pm

Hello,

Currently editing a GreenScreen shoot. As expected, after applying a Chroma Key and Color Corrector Filter I need to render the footage after making any type of change (new backgrounds, adding movement etc) in order to view the footage. What’s throwing me off is that the other editor (who has the exact same settings and filters as me) does not need to render their footage in order to view their timeline after making edits. At most they are getting the green (Preview) line at the top of their timeline.

Can anybody explain this to me? Working in this setting would save me a lot of time.

Thanks,
Nick

I can think of a couple of reasons…

First, do you have different CPUs/Video cards? RAM? FCP?

Second, are you doing anything like a Drop Shadow or Motion blur (both are NEVER RT)

Best,

Are the RT playback settings set to be unlimited?

Hey Jeff,

Thanks for the response. Here is the info for both systems:

Mine System:
CPU – MAC G5 Version 10.5.8 (Processor 2 x2.8GHz Quad Core Intel Xeon)
RAM – 6GB 800MHz DDR2 FB-DIMM
Video Card – ATI Radeon HD 2600
FCP – 6.0.6

Other System:
CPU – MAC G5 version 10.4.11 (Processor 2 x 2.66GHx Dual Core Intel Xeon)
RAM – 7GB 667MHz DDR FB-DIMM
Video Card – NVIDIA GeForce 7300 GT
FCP – 6.0.6

Noticed that it is not happening so much with shorted (40sec) sequences.

Thanks,
Nick

Hey Jerry,

Thanks for the response. RT was set to SAFE. I eventually had to switch mine over to UNLIMITED in order to speed up the work flow. Unfortunately I am getting Dropped Frames in the Playback as soon as I use 3 or more video layers.

Thanks again,
Nick
