In the event that you've recorded HEVC video footage and do not have a compatible device to play your recordings, there are a couple of options:
1. Convert Your HEVC Videos to the H.264 Codec
Using a video transcoder application or software, you can covert your HEVC videos to H.264 (compatible across all devices) with minimal loss in image quality. HandBrake is a free, open-source application that many people recommend.
2. Video/File Hosting via Web
Upload your video to YouTube or another video/file hosting service. Once uploaded, you should be able to play your footage on any device compatible with the website, as you'll be able to utilize their compression.
