You can mark specific moments in your video as they happen with HiLight Tags. These tags make it easy to find the best highlights to edit and share.
You can remove these HiLight Tags on your video clip by opening the footage on playback screen, then tap the orange markers or badge along the playback slider. This process is pretty much the same as deleting the tags through the Quik for Desktop applications.
