Render settings to avoid banding
Hi all,
A clip has a very smooth gradient in the back.
Smooth on the AFx screen, it turns banded (noticeable color steps) in rendered QuickTime .mov
Tryed various QT settings: Animation, Photo-jpeg as advised by a stock, all at highest quality setting – all the same, just the band step varies.Any advice on which compression to use (except uncompressed tiff’s) to keep shallow gradients smooth?
Kind regards,

if it failed with animation, that means you need to bump up your project settings to 16 or 32bpc. The banding should be visible in your viewer.

Sometimes, if the gradient is too shallow, it’s even beyond the ability of 16 or 32 bpc to smooth out, especially when the final format is 8-bit (e.g. Avid) or 10-bit (e.g. DigiBeta). Sometimes.
In those situations, you would need to add a bit of noise to the gradient. Search the COW for “banding” for more.

Yes,
and HDV( Sony’s native) is only 4:2:0 I believe.
