Toon Boom not exporting properly

I created a short animation which begins with an object sliding across the screen. But when i exported it that part was shortened and the rest of the animation was out of sync with the audio. Any idea what going on and how to fix it?

Difficult to say without seeing the project.

Try and avoid using mp3 format audio files
as it’s a compressed format and can lose synch.

Wait, I should have looked at the export more closely. It looks like the only problem is it exported at 24 fps when I animated it at 12 fps. Do you know how to fix that?

You could fix it by going to Export Movie and
in the Export window clicking the Options…
button. Click on “Settings…” and you can change
the frame rate to 12.

I just tried that, but it still looks like it exported at 24fps…
