I’ve checked the very few other scope skins around and the .AR240. format tag is indeed the most common. If either .AR178., .AR200., .AR233., .AR235. or .AR240.

If none of these five tags are present, the masking aspect ratio will rely on the custom value set in the skin settings. After video playback has stopped, the aspect ratio will also fall back to that value.
I’ll push the changes later today. Then you’ll be able to test
