Your apps and site look awesome, congratulations.

For whatever reason, the hero video at https://lunar.fyi/ makes Safari use 100% of all cores, Webkit.GPU goes nuts, WindowServer unresponsive… works fine on Chrome however. Monterey 12.5.1, iMac 5K, 27"

Thank you!

I think that might be because Safari uses the HEVC version of the video. I'm also seeing 25% usage on an M1 Max MacBook, which is more than I expected.

Firefox and Chrome don't have noticeable CPU usage. They only support the H264 encoded video.

I might have to reencode the video and optimize for hardware decoding. Default ffmpeg options were not enough apparently.

EDIT: it's actually because of the HDR section from https://lunar.fyi/#xdr

Safari is the only browser that can activate the HDR subsystem on these Display P3 screens, and by doing that it taxes the GPU more when playing back video.
