This conversation has been merged. Please reference the main conversation: Lightroom Classic: Ability to export 4K video
* 'export video' - exporting takes an insane amount of time ie 45 minutes to 8 hours... I checked on Mac 'Activity Monitor' how much RAM - uses minimal amount. Also was only using ONE core (my computer has 8) Of course I have tweaked all the right settings to maximum - still no effect.
