Camera Border Restriction

Ok so I am trying to animate a video but when I go over what the camera can see (into the gray area) it doesn’t cut me off like in Flipaclip on my phone. I was wondering if there was a way to make it so that if I draw into the gray it could cut off

No, currently there’s no way to have your strokes completely cut off when you leave the camera area. We already have that written down in our bug tracker as a future improvement but so far we’ve not gotten around to implementing it.

It should be noted that the content outside the camera area make absolutely no difference in the exported video. Everything in the gray area will get “cut off” when you export your animation through any one of the export options.
