dropped frames

I suspected that your issue came from the H264 High, but coffee lake still has support for that codec. What OS is the client you're having issues with? I have a similar machine as my desktop and it's pretty poor at video playback in general, particularly through the browser. I haven't measured dropped frames but I avoid it at all costs if possible. If you're running Windows, you might try a better client like JMP and see how that performs.

In addition to the link already provided, we have an off-topic discussion around using ffmpeg CLI for re-encoding videos that has put out done good content. I need to get back to my development on a script I want to share for adaptive encoding, but there's a lot there already and you can ask any questions you have and I'll try (or somebody else will) to provide a good basic start where you can ask any follow-up questions you have.
