Can't Export FCPX Project without Re-encoding?
Hi, I am trying to compile separate video and audio recordings from recent zoom meetings into self contained video files after syncing the audio track in FCPX.
In the project I made sure to match the resolution and frame rate to the source media and I can successfully edit and scrub on the timeline with no transcoding or playback issues. When I go to share the project as master file with source video settings FCPX keeps trying to re-encode the video instead of just muxing the audio into the video at specific start/end timecodes. FCPX is estimating turning a ~5GB file into a ~5.5TB file. The source videos are full screen video recordings of about 60-90 mins from my MBP2017 done with QuickTime.
In theory I think I can also use FCPX to find my desired start/end frames for the video and audio files and use ffmpeg to mux the streams without reencoding, but that would probably take me longer to figure out the correct commands. I feel like this is something that should be in theory really easy in a pro video editor with a GUI. Given all the media is being recorded and edited via Apple OS and software is there an approach/setting I'm missing or messing up?

Thanks in advance for taking any time to look at/into this.
