Resize multiple mixed resolutions to half size

Hi

Trying to find a simple way of resizing multiple mixed resolutions to half/ quarter size without having to enter manual resize dimensions for every individual bit of footage?

I have loads of stills of many different frame dimensions and just want to quickly make them all half their original size, but still full frame.

Thanks
Alec

If they are stills, I could suggest resizing them on the OS level. If you’re on Mac, this is really easy with Automator, with online tools or even with Preview…

Thanks I can explore that as an option
