Creating shape for Mask file


I like to make my own shape for Mask file, mainly for cool transitions. I tried to make an mp4 but I didn’t get the desired result.

How is the built in shapes made? Is it mp4 or some image?

Our very own @bentacular made an excellent tutorial on what you’re wanting to do.

The manual filter is Mask: Simple Shape, which you can pick from square, triangle, diamond, or eclipse. You can add more than one Mask:Simple Shape filter to make unique shapes.


That’s a nice tutorial but I would like a smooth transition. I think I have to work on that mp4 transition video.

I do wonder how transitions is implemented in ShotCut, because with the built in transitions you can specify edge softness and it can be of different lengt.

Thanks for the shoutout!

You can also use a video file instead of an image, similar to the technique used in this tutorial
