As soon as I import any of the footage from this client, I get immediate visible banding! But it is a type of banding I've never seen before. I don't know what is causing it or the source of why it chooses to do this. It happens mainly when there is movement. I have uploaded images below

The Footage:
H.264
1920x1080
8-bit
(Works fine in Premiere)

I thoroughly enjoy using resolve using Resolve and I hope I can solve this issue as soon as possible.

Looks like interlaced footage in a progressive sequence.
Check your project sequence settings and the footage attribute settings. There is a mismatch.

From my knowledge, it looks like everything matches up. I have tried a wide range of options that could have also worked and i still get the same outcome. I am not knowledged in "deinterlacing, interlacing or progressive sequences", although ive tried to solve the issue, how would you suggest I go about changing this?

Also, i should say it happpens even before the footage is inserted into the project (as I view it in the media storage pool)

Try 'Clip Attributes' - 'Enable Deinterlacing'

The option to “enable deinterlacing” is greyed out

Its a feature only for the studio version.
And yes you clip needs deinterlacing.

Edit: unless of course you are delivering for interlaced broadcast.

Hey,
This is indeed not what's specifically called banding here, but just interlaced footage... Therefore it's not bad or good, it's just that 1 frame is made of 2 x 1/2 frame.

Now, if you deliver for broadcast, just stop bothering and edit as you would anyway, the result will be ok; if not, either cut the same way and deinterlace in the end (when re-encoding for the final destination), or deinterlace before when making proxies if you cannot bear the visual inconvenience (for example when making ProRes from H264), but this less handy of course...
