File File size how
.webm 550.5 MB downloaded Good quality. Not immediate acceptable on macOS (webm format).
.mp4 1.03 GB downloaded Good quality. Feels like same as webm but significantly larger… (probably can tweak settings and re-encode/transcode for smaller size)
.h265.mp4 1.03 GB transcoded

transcoding from mp4 using ffmpeg -i x.mp4 -c:v libx265 -vtag hvc1 x.h265.mp4 took almost 30 min (im2720).
