Hi,
To add Mads’ advice, you cannot exactly do it as he recommended but you can achieve it this way.
First, go inside your multicam clip and assign a video role to every angle. Right-click the video and choose assign video angle and probably you don’t have angle 1 or angle 2 roles so edit roles and create new video roles. Then assign every angle. Then go back to your edit timeline and open the timeline index with command F, and type angle 1 and select all in the index, all angle 1 clips will be selected on the timeline and copy and paste them onto a new timeline. You will see the name of your multicam clip instead of angle names but don’t worry it will select correct angles. Place a blank adjustment layer between angles to keep every angle as if they are on separate tracks. Do this for all your 3 angles. This way you will have them all on the same timeline. And you can export 3 angles in a high-quality codec like Prores 4444 so the colorist can use those tracks.
