I haven’t burned it. It plays glitchy on this shot (see link below) on both MPC and my Zappiti 4K HDR mediaplayer.
This is still in v2.0. Its obviously an issue of something specifically just not playing nice with Premiere’s export. I even tried upping the bitrate substantially and just outputting this sequence…comes out pixelated every time. Ah well. Not worth sweating over a few seconds. Definitely peculiar, though.
