Can I draw in smooth.video?

Yes, with a simple brush: the drawing becomes an image you can move, scale, rotate and fade on the timeline. It isn't made for drawing each frame.

Yes. Add an audio file and it's included in the MP4 or WebM. A GIF can't carry sound.

No, and there's nothing to join.

Can I open Motionity projects?

No. smooth.video opens its own .smooth files: bring your images, videos and audio over and rebuild the animation.

Where are my projects stored?

In your browser, as with Motionity. Save a project as a .smooth file to keep a copy or move it to another computer.

Yes, as well as WebM with transparency, GIF, PNG, JPG and WebP.

Motionity vs smooth.video

When smooth.video fits better

The animation is made of things that move: a title, a photo, a logo, a sticker, a chart. You want sound in the video, more than one layer, and no ads, without a membership.

You liked the idea of Motionity, a free motion design tool in the browser with no account, and want one that's still updated, exports MP4 and transparent WebM, and has templates to start from.
