that’s possible. how? first, seleclt all the frames in the timeline of the mc you want to copy…then, copy the frames by pressing CTRL+SHIFT+C (or right click and choose “copy frames” from the option menu)… and finally, go to your main timeline, creat a new layer, then, paste the copied frames by pressing CTRL+SHFT+V (or right click then choose “paste frames” from the option menu)… i think that’s it…
leftover: in some intances, converting the properties of that clip into “Graphic” will somewhat solve the problem…
