Screen recording: screen captures come out too small after changing story size

Hi community,

Following scenario: I have existing projects for which I recorded screens and inserted them in view mode steps. The story size when I did the recordings initially was just 16:9 (default). We ended up getting the logos and images that we used compressed at publishing, which is why we had to adjust the story size to 1920x1080 (custom) to ensure we got the images in the right quality. However, in a new story that I have created and set to 1920x1080 story size from the start, when I do a screen recording and resize the recording area just like I did before, I get the inserted step by step recordings somewhere around 3/4 of the size of the full slide and there is no way of adjusting this in any way.

Any ideas how I can get my recordings to fill the slides like they did before I changed the story size? We have built our entire layout around having recordings filling the full slide since there was no way to adjust the screen capture size on the slides directly when using step-by-step insertion, so now having to change our whole layout AGAIN just because Storyline doesn't allow fitting a screen recording done in 16:9 but lower resolution to the story size of FullHD without the ability to upscale it loss-free that would mean delay in delivery of the finished modules and further impediments.

Please advise!
