Hello everybody,

I am editing a a split-screen film (two screens film). I first tried to edit each screen in a seperate timeline and then nest them into a final timeline, but that was really time consuming for the sync between the two images and for the audio editing as well (since the best thing would be to have the audio for the two screens playng together always). So I tried editing them at once, in one single timeline, using black screen masked on top of them. The problem is I am using different sized footage, and when I re-scale one image inside the mask, it spread onto the other "screen". And it is too time-consuming to always crop each image after re-scaling it. Any thoughs on that?? Thanks!

Hi, for me the fastest way to work this kind of job is to apply on each clip transofrm effect and crop effect.

Do not use position and scale of the clip.

With crop effect of each clip you create masks for final split screen and with tranform effect you set zoom and position of each clip.

Thanks for the reply. Unfortunately, since lots of clips have different sizes, I wouldn't be able to copy and paste the crop effect for them, making it extremely difficult to achieve the same exact screen size for each one in the final split screen film.

Then you make separate sequence for split screan and each clip in each sequence is scaled to fit, than put this two sequence in final sequence and again use transform and crop effect.

That was my initial plan, but it would make the sound editing and the sync
between the two screens too difficult.

For this reason before editing you copy audio from clips  from two sequences  in main sequence, link them and edit audio and video together.

Thanks, Stefan P, I believe that's the best way to go !
