To chop a video in Capturespace
In the Library tab, select the recording you would like to edit.
Click on the Preview Media icon and then click on the Preview button at the bottom of the screen.
Select Chop from the menu on the left. Two blue markers are displayed on the video strip.
Use the Start and End markers to highlight the part of the recording you want to retain. The region to the left and right of the markers are greyed out. Chopping is only possible if the resulting video is longer than 10 seconds.
Click Apply and then click Done.
All edits made to the recording will be made to the original file.
