I have saved my original media on an external ssd and created optimized media in the same place. Now I finished editing on my old mbp 2012 and would like to test playback performance and video quality differences of the original files on my old MacBook and a new MacBook Air m1. Is there any option to use the original files instead of optimized media without deleting optimized media? I tried to rename the folder but FCPX notices and relinks automatically.
Thanks! This worked out, even a new MacBook Air m1 does not playback Sonys XAVC-S UHD 10bit 50p footage well when its not optimized. There's just a little color correction and a broadcast safe filter applied on the timeline - the project is 50i HD. I did expect the MacBook to handle h264 based codecs better - but I must admit it only has 8gb ram, maybe that's the cause. When I use ProRes optimized footage from the same SSD it plays back well, so SSD speed is not the problem.
