Yes you can.
Clipchamp Utilities lets you convert your GoPro videos (as well as videos taken with any other sports action camera or digital video recording device) to other video formats. You can also compress GoPro videos to reduce the file size, which makes it easier to store them or share them with friends & family.
Clipchamp Create lets you edit together your GoPro videos and add text, effects, music, and more. Note that on some computers you may experience errors or slowness when editing 4K GoPro videos due to the processing power required, so we recommend compressing the videos first using Utilities before adding them to Create.
