You're the one with comprehension issues - in the video above he was forced to state what settings he used in the comments below. I quote him:
"4K HQ, 23.98p, IBIS on, AF ON, ALL-I (even though that doesn't matter in this case)."
He also says in the video using an external recorder 'solves' 4K on the R5. This is an outright lie - he hasn't tested it at the higher frame rates. You can't trust a word he says if he's prepared to lie like this.
Look at the pretty much universal praise for Gerald's video. I know who I trust rather than this liar.
