If he's putting music on the video version why not do the same on the flash version? The flash has better visual quality than the video at less than 10% of the file size. https://files.catbox.moe/as5omv.mp4 Despite the video having 1860x1594 resolution and being 38.7 MiB.
Disrespecting flash like this doesn't make sense. -8 should give equal or better treatment to the format that can give the best presentation of his work.
