Hello CM120884,
I gather, from what you're saying, that there's no obvious banding in the original clips but it's apparent in the produced file. Is that correct?
Colour banding, or "posterisation", is a display issue on monitors & TVs where there aren't enough tones available to render/display the original gradient.
Could you please provide some details?
Properties of the original video: resolution, bitrate, colour/bit depth etc
Properties of the produced video
Any adjustments made during editing? e.g. application of LUT, colour adjustment, etc.
Even better, if you could also provide screenshots or a short video sample members might be able to offer some advice.
