Edit video length, keep time and date

I have about 300 videos that I would like to permanently delete frames from the beginning and end, and preserve the original creation date. I currently just use the stock Photos app to view my videos. Photos has a "trim" feature but this doesn't permanently delete the frames, just hides them, so the videos much larger than I want. Ideally I would like to work in the Photos app, maybe use some sort of plugin/ extension, so that I can delete frames and still keep the original creation date and time. Any ideas?

doesn't permanently delete the frames
I believe you need to export/share the clip before it permanently applies the trimming. This is how it works in iMovie and other video editors. This also takes a bit of time and computer power, so maybe that’s why they pretend they made the edit.

original creation date and time
If you note the original date and time you can adjust the new date and time to match the original (under Image > Adjust Date and Time). There is a terminal way to fiddle with the date and time directly, but it is more involved.

There is no automatic way to keep it original after editing since you are changing the clip (but it should keep the date created and only change the date modified).

Thanks for the input. I'm not very good at Automator, but maybe this is a good Automator task. First I trim all 300 videos in Photos app, then let Automator export all to desktop, change modified date back to original creation date, and then import back into Photos app. Any idea how to write that script? :)

This is just a ridiculous situation. Apple needs to allow people to actually permanently delete parts of videos in Photos. This is not a minority feature request. Everyone using iCloud Photos will want to do this at some stage.

Agree 100%. Glad to know I'm not the only one that doesn't shoot a perfectly cropped video on the first try. I spent a good hour searching for this functionality in Photos/ macOS thinking it MUST be there somewhere. Anyway, will submit a feature request to Apple.
