To view, manage and edit your GoPro videos on a home computer, you can use our free software GoPro Quik for Desktop.
GoPro cameras create MP4 files, a format that is supported by many video editing programs. For other editing options on your home computer, we have had several customers give good reviews of Pinnacle Studio HD, Davinci Resolve, Windows Movie Maker, Adobe Premier Elements, and Apple's iMovie and Final Cut X.
For more advance video editing applications, please refer to DaVinci Resolve (Free Version) or Adobe Premiere Pro CC (Paid).
VLC Media Player is also a free downloadable video media player that supports MP4 H.264 files.
