Artifacts in Enscape 2.9 video render image, but not present in normal render image

Hi,

Not sure if its a bug or something that I'm doing wrong, but as you can see from the attached images, when I render a normal image, It comes out fine.

If I try and render a flythrough video, I get a lot of artifacts appearing. I've tried all different quality setting, incl lossless, and they come out with artifacts all over them. I was just running some tests as i will soon need to render out some flythroughs for a client presentation.

Would anyone be able to give me any advice please

Many Thanks,

Jonathan

Strangely, the above ones were rendered from ArchiCAD 23 plugin and just created some more from an ArchiCAD 22 model and haven't had any issues. Nothing else has changed with the settings so I'm really stumped now.

Just to stress the new ones that worked fine were a different model and not from the one in the original post
