You can trim videos attached to cards inside CueCam.

This is non-destructive and will not affect the source video (or your file size!)

Start by clicking the video attachment (you can also use the Card sidebar).

Click “Trim”

It’s easiest to drag trim points in the large video preview.

Don’t forget to press “Trim” when you’re done.

Now this video will start and stop at the times you set.
