If you ever need to do a full 4k export you can simply copy/paste the 1080p timeline into a 4k project and that will enable 4k export - all the edits will still be there. I have never tested this before but that apparently includes export performance. All of the above tests for FCPX and Compressor used a 1080p project since that is the common practice for editing and exporting 1080p or below from 4k material.įCPX enables full resolution of the underlying 4k material when editing in a 1080p project - you can crop/zoom into the frame and still get the full 4k benefit, yet many operations will go faster.

Exporting 720p from a 4k project was about 2x slower than from a 1080p project. I did two final tests comparing FCPX export performance of 4k material using both a 4k project (ie "sequence"), and a 1080p project. 12 mbps is more than double the bitrate that Youtube recommends for 720p. I generally use single-pass on all proof copies and (if I remember) switch to multi-pass for the absolute final export, but sometimes not even then.įor H264 720p export using the above settings, FCPX uses a bitrate of about 12 mbps, which is not far from the 16 mbps you selected. This is single-pass but I cannot visually see any difference between this and multi-pass. In general I'd recommend exporting directly from FCPX using the Computer/H264/Faster Encode setting. You are on a nMP which does not have Quick Sync but in the previously-posted video test on a nMP, FCPX was still much faster than Premiere. individual tips plus auto cover usually edit together videos percent fast.

I watched your video and ran 13 different tests using both FCPX 10.3.1, Premiere CC 2017 and AME 2017 to try and figure this out.
