Using Fusion drops footage resolution

Hi there

I have some footage, i go to fusion, i put any effect in the node chain, immediately the resolution drops dramatically, if i remove the effect and reconnect mediain to mediaout, the footage remains corrupted.

I have no idea why this is happening, have looked into the settings of fusion but that is set to a HD resolution

Thanks in advance

Delete the comp and then Set ur timeline res to UHD.

So turns out i was using low res filler renders before getting to my HD res frames to help match with music. Resolve was thinking that the entire clip was the same resolution as the start of it
