Not bad! The range of the CRF scale is 0–51, where 0 is lossless, 23 is the default, and 51 is worst quality possible. Running this spits out a 30.4MB file, around 61.5% smaller, and the quality is fine for my purposes. Now based on my previous post, we could start off by re-encoding just the video at a slightly higher crf factor, like this: ffmpeg -i GOPR5687.MP4 -c:a copy -c:v h264 -crf 22 output.mp4 I'd like to retain a decent quality, but reduce the size from 78.9MB. This video was shot at 2.7k to capture the amazing landscapes in New Zealand. Here's our test video: Snow capped mountains in NZ, shot at 2.7k, weighing in at 78.9MB for 10s Hopefully there is enough information here so that you can tweak as necessary for your own camera If you have a different model GoPro, some of the metadata might be slightly different (earlier GoPro's do not have a GPS sensor for example). If you just want to skip straight to the final command, scroll to the end. Here I will walkthrough the process of compressing a video shot from my Hero 5, using FFmpeg. That's because there are additional streams embedded in the videos, as well as proprietary metadata.

I've previously written about how to compress videos generally, but for GoPro clips we need to do a little more.
Whether you are uploading videos to the cloud, streaming them via a home NAS, or just short on drive space, you might find yourself wanting to reduce the size of your video files. With the right conditions and settings it takes some really nice video, but sometimes they're just a little bit too space hungry for my liking. I've owned a GoPro Hero 3+ and now more recently a Hero 5. Do you have loads of GoPro movies eating up disk space? Looking for a way to compress them, but in such a way that quality is still very high and they continue to play nice with GoPro software, like Quik? I did too.
