Can't save animation as anything

I just made an animation today, and when I click save it’s says it saves. However, if I click ‘save as’ the only option was “All files.”

Is this a problem with my computer or the program?

Save as in Toon Boom Studio is like a copying the project on other location. It can not overwrite existing project. Instead, save will overwrite existing files as long as the project is saved once. Or it will ask you to save on where.

If I understood your question, you want to save your animation as a video file? You have to go to [file>export movie] then select what format you want(avi/mov/png image sequence etc.). You can also change other things like picture and audio quality if you want. Then choose folder and click export, and voila, your animation is saved as a video file. I hope I was helpful.
