Comment on N100 Media Serving Efficiency with Quick Sync

One caveat worth noting is that as soon as subtitle burn-in comes into play (especially at 4K), then you’ll easily hit 100% CPU usage and encounter stutters. It’s less of an issue if you’re using good clients and have control over that, but may be a problem if you’re sharing with your family and they have problematic playback clients.

what is subtitle burn-in?

Subtitles being “burned into” the frames instead of being a separate track, also known as hard-coded sometimes. This enables one to use subtitles on devices which cannot traditionally use them or screw up the display. But this means the server needs to re-encode each and every frame, which is a massive load on the server.
