Footage: 60fps, 1080p, few clips at 120fps and slowed down.
Sequent: same as footage.
Export settings: 1080, 60fps Render at maxiumum depth / maximum render quality checked. Bitrate, CBR 100, 150, VBR 2 100/150. Same results regardless of settings. Profile - high, Level 5.2.
Time interpolation set to frame sampling.
I've exported without and with adjustment layers, on which I had 20-25% opacity LUTs.
I have exported videos with the exact same settings in the past and have not encountered these issues. I'm a little bit annoyed as this is literally my simplest video to date in terms of transitions, coloring, and editing in general.
Yeah it looks fine. The only ones I could argue don't look 100% are the car timelapses, which are also seen on the test upload linked, but that wouldn't explain why the 1st one shows pixels and subsequent ones do too.
