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).
