Hi everyone
I just finished cutting a 4k music video with Joe’s second method, and though I’d share my experiences and problems.
Raw footage 4k (not positive of camera, Sony I believe)
FCPX 10.1.3 on a 2011 MacBook Pro with 8 GB ram
The raw footage was unable to playback on my system, so I transcoded the media to Proxy and cut on a 1080p timeline. I’m now on the exporting phase and running into some issues.
Exporting the 1080p timeline was fine, it wasn’t until I tried to scale back up to 4k that errors occurred. First thing I tried was duplicating the 1080p project and manually changing the settings to 4k. Everything looked good until it background rendered, then my viewers just showed a solid green screen of death. I exported a small section and the rendered area was solid green and the unrendered section came out normal.
Then I started a new 4k project, copy/paste timeline, and again same green screen issue. Exported a sample and same result as above.
TURNED OFF BACKGROUND RENDERING, exported sample, and it looks normal! Very annoying, but not the worst thing I’ve had to deal with. I am currently exporting a final unrendered 4k version, which looks like it will take a few hours. I will update this thread with the result.
Hope this info is helpful
Cheers
