Re: Video not playing


Hi @kevins417,


May I know the settings you're using?

If you're editing 4k video on Quik even if it's compatible to your device it might not work.


But you can use other software instead.

Hi Jay


Many thanks. The files play video in quicktime player but do slow after about 5 seconds into the video. Quik does not play them. Many thanks for your help.

Re: Video not playing

Your video is recorded in HEVC and unfortunately your computer is having a hard time keeping up. You can try converting it to h.264 with Handbrake and see if it works better on your machine.

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:

Convert Your HEVC Videos to the H.264 Codec - Using Handbrake, a free, open source application, you can covert your HEVC videos to H.264 (compatible across all devices) with minimal loss in image quality. Please reference How to Convert GoPro HEVC Videos to H.264 Using HandBrake, for step-by-step instructions.

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. *NOTE: Being as you will be using a webservice to play back your videos, there may be a decrease in image quality simply due to web compression or your connection speed.

Also, try NOT using the dedicated GPU (Radeon Pro 560X).

Many thanks.


Video compression on the gopro is set to H.264 + HEVC

Re: Video not playing

At 1440p/120fps the camera will always use HEVC.
