I’ve using screen studio since it was beta release. Making alternative is a start but if you want to be better, I would suggest adding what’s missing from screen studio.

Few things I would like to see:

- Ability to add images in the time line, think of intro/outro.

- Ability to add notes (text) on frames to explain something or highlight an area.

As some comments mentioned, running locally is a must, and I have no problem paying for it.

Good luck
