When editing videos I run it to problems when using the mask filter. First of all when the filter is applied the video player lags and that gets even worse when you apply more mask filters. Second I do know that there is possible to make custom masks but you can’t cut something out that’s moving and with a complicated shape. My suggestion is that you should add a new custom mask filter which would allow you to make custom masks in SC with keyframes on the video player much like in Adobe Premiere. It could be like an easier way to make custom transitions and reworking/adding to the mask filter should make quite a lot of people’s lives better. I hope you consider this idea and add it in the future. Best of luck to you all.
This is planned because the engine supports it, but we have not yet written the vector drawing user interface for it.
