HD render times
I’m working on a HD project with EX 1080i footage as well as some HD jumpbacks. I’ve done simple HD projects before but this is the first time I’ve done compositing and render times for adjusting ANYTHING are huge. I have a 20 sec jumpback that every time I move it it takes 2 minutes or more to write video. Also, when I looked at the item properties it said the file was 1.1 gigs. I rendered it out of juicer as a 1080×1920 QT. Is this normal?? The render times are killing my workflow!! I’ve tried different sequence settings but to no avail. Any help would be greatly appreciated. I’m also new to FCP so I’m pretty sure I’m not doing something right.

Rendered out of the juicer at what codec? Many HD codecs can be 1920×1080.

“The render times are killing my workflow!! ”
I feel your pain. We just recently started doing HD shows and many of our interviews are done green screen. Ouch! Our renders went from minutes to hours.
This is why you’ve got to get the latest, greatest, Octo core Mac Pros… it makes the renders manageable. My only suggestion is to either buy the latest, fastest, or deal with it. If you can’t deal with it, direct your frustration and emotion towards Apple’s “Request a feature” forum.
Ask them for distributed rendering in FCP. If you can send FCP rendering to a render farm, that would go a long way towards making this workflow more palatable.Good luck.

What codec?

[Jeremy Garchow] “What codec?”
I’m working natively with the XDCAM format which is 1080×1920. I forgot to mention my machine is a 3 month old octo core with 4Gigs of ram. Will I see much improvement by adding another 4Gigs? Also, it seems my main issue is with the jumpbacks, it just seems odd to me that FCP has to re-render every time I move a HD jumpback. As I said I’m rendering the JB’s out of Juicer at 1080×1920 QT files. Should I be converting them to the EX codec and how do I do that? Again, thanks for the help.

Yes, it will have to re-render them unless you render them at the exact codec and frame size as your media.
If you want them to be correct for your timeline, export them as a self contained movie from FCP.

Keep in mind that 1080p is almost like processing 2K film. It’s an incredible amount of pixels compared to our old SD video.
I would suggest not editing in XDCAM, it’s an incredibly lossy format with long MPEG-2 GOP frames requires a lot of processing power. Plus its 4:2:0 color space makes it crummy for chromakey or motion graphics. I would suggest working in a format that supports 4:2:2 and only intraframe compression (like Uncompressed or ProRes).
