Banding is where subtle gradients run into the limits of the bit-depth in the codec, often amplified by artifacts from compression.
This cut my troubleshooting time down considerably, as I didn't have to keep exporting footage. They do not appear if I haven't pressed "Render In to Out".
The flickering lines then appear when I preview the timeline. I did learn that I can replicate the issue just by setting In and Out points on the timeline and rendering inside Premiere i.e by going to Sequence > Render In to Out.
Rendering the same footage on a Macbook (I usually work on a PC). Installing an older version of Premiere, downgrading the project, and rendering out of the older version. avi, very high bitrates, CBR, playing with every encoding settings Rendering the project in every imaginable way i.e. Using opacity keyframes from 100 > 0 > 100 instead of dip to black. Removing all effects except dip to black i.e just Dip to Black on pure raw footage. Switching from GPU to Software renderer. Aside from countless hours of Googling, here is a list of things I have tried: I've spent the past two days trying to find a solution, to no avail: the problem continues to appear. Here is an example of the problem: (the password is "help")ĭoes anyone have any clue as to why these flickering lines are appearing during fade to black transitions? How could I get rid of them? After watching the render, I noticed that on every fade to black transition, a bunch of flickering lines would appear on the white wall behind me. Everything looked great and I rendered the project out. I have completed my edit in Premiere and used a couple of "Dip to Black" effects as transitions between different moments of my performance. 
The footage I received from my cameraman was shot on a GH5, and it's technical specs are 23.976 fps, 1920x1080, and H.264 10 bit 4:2:2. I am working on documentation of a performance/musical instrument design project I completed in the springtime.
