Banding issues

[eyeland]

I have been experiencing some banding issues in my raw clips, and I am wondering if this is merely the effect of pulling up an underexposed shot, and if so, how to best deal with the problem (appart from not under-exposing)

The issue is best seen if you download the vid instead of streaming it from dropbox

Could be the application you're using to display the video? For instance in AE, you have to more up to 16 or 32bits. Banding can occur also if your monitor is not displaying enough bits (some monitors don't). I remember seeing heavy banding on some stuff I shot on the RED One a while back, and it turned out to be my monitor and when we played the same video on the color grading monitors the image looked fine.

Unfortunately I dont think thats the case. AE is in 16bit mode and I am seeing it on all monitors.

The banding is vertical? Looks like the problem from early versions of raw2dng? Are you using the latest? Other than that maybe it's due to underexposing which looks to be the purpose of your test? Which really don't understand as camera raw / h264 isn't film to push and pull.

As long as you get your lighting ratios how you want the final image to look, then expose for good skin tone and darken shots in post?
