When capturing movie in any resolution higher than 640 x 480 the preview window cuts off the image so you can’t see the video rendering completely. On 1920 x 1080 and higher you can just see the top left of the image. It’s not scaling properly.
I’ve exhausted all my research attempts and can’t find the answer to fix this. I’m thinking this must be a bug.
This problem does not exist in UE versions 4.23 and earlier, just in 4.24, 4.25 and 4.26 preview.
