In my quest to optimize media serving capabilities, one feature that stood out for testing was Quick Sync, particularly its hardware acceleration potential. I embarked on a comparison between Jellyfin and Emby, evaluating the efficacy of Quick Sync and its impact on system performance. Utilizing a sample of media encoded at 2160p via x265, I conducted several tests, the results of which are presented in the accompanying charts. Without Quick Sync enabled, the CPU resources of the system were pushed to their limits.

    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.

        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.
