Access Scripts from saved videos (screen recordings) within the Photos App?

I noticed that even if you add all the inputs to your script, you can’t run a script from any of the videos in your Photos app. I like to do screen recordings pretty frequently and it would be cool to be able to run some scripts on them. Weirdly if it’s a video in the files app you can run scripts on it, so it seems like maybe just an overlooked feature. Is there a workaround, maybe a way to change the default save location for screen recordings or something?
