Hi everyone,
Last week I was attempting to export an 8 minute piece edited in Premiere Pro CC through Adobe Media Encoder. The media was mostly 1080p 23.976 AVCHD with a little 2k ProRes mixed in. The footage was shot S-Log in poor lighting so there was a fair amount of LUTs and liberal use of Red Giant Colorista II. I also applied an adjustment layer over the whole timeline to with an Unsharp Mask for added clarity.
I saved my project, left Premiere open and switched over to AME for export. I imported the sequence into AME and selected a 2-pass Vimeo preset, using GPU Acceleration (OpenCL). When I pressed encode, I watched my CPU usage rise (as expected, mostly attributed to pproheadless) in the Activity Monitor. For my first edit, the export took about 20 minutes, no big deal. However, after the client made some minor tweaks, the project wouldn't export again. I ran into a variety of issues trying to export again, even though the changes made were minor and didn't involve new effects:
- Attempt 1: The export took nearly twice as long as it originally had and then stopped with "00:00:00:00 remaining". I let it sit for almost an hour but I was on deadline and needed to try again.
-Attempt 2: After reboot, the export started as normal and seemed faster than before, then it simply stopped. The pproheadless task in the Activity monitor dropped to almost no activity, without showing an error or stopping the enode. Once again, I let it sit for about 30 minutes before cancelling, had to try something else.
Attempt 3: I tried the export with "Software Only" encoded selected. It ran through in about 3 hours, then crashed and failed when the export should have completed.
I ended up taking the project and media files to another machine for export. Does anyone have any ideas on why this would happen? And what I can do to avoid it?
