I often shoot in 1920x1080 and then edit in 1280x720. Because I do a number of 'interview' projects that only need to be deliverd in 720, this allows me a 40-50% upscal on my interviews (basically a closeup and medium shot without having to change the camera during shooting) In FCP I never had any RT (real time playback) issues doing this. I have found in CS5.5 that when I do this, every single clip needs to render because it's being scaled. If I do a second layer for b-roll it gets worse. (note, just dropping in the single clip gives me a red bar and if I place a b-roll clip on track 2 over the interview, it stutters and pauses).
Here's my question. I am working on the following system:
MacPro 4,1 (2009)
2x 2.26 GHz Quad Intel
System & Software on Internal 7200 Drive #1
Media on Internal 7200 Drive #2 (not a raid)
Project on Inernal 7200 Drive #3
Is there anything I can do short of a complete new system that will improve the RT performance of using 1080 footage in a 720 sequence?
While I know any of the following will help a system, will any of the following alleviate this problem. If so which one and how much (or what recommended product) for each?
-Seutp Raid0 ?
-Faster Graphics Card?
Is there mac system that will make this work without having to render every clip?
Will Premiere Pro Next address this issue?
A graphics card that allows GPU acceleration would probably do the trick.
