Rendering without extra alpha

Dear Synfig community,

 I am a novice 2D animator.  I have started creating animations for games, and I usually export in .gif format.  I have a small animation for a zombie walking, however, I want to "crop" all of the extra, unneeded space.  Is there any way to do this?

The file:

Any help is much appreciated. Thank you!

 Sincerely, KetoAnimations

Hello Keto and welcome here.

You can adjust the canvas size, have a look to “Expanding the Canvas” and to the opposite.

By the way, Synfigstudio has a big learning curve, if not already done, i suggest you to do the step by step tutorial from the wiki.

Have fun !
