I use a program called Panorama to do this, you can get it at https://www.provue.com. It’s basically a database, but it has an interpreted coding language built in. You can create functions like tcdiff(“01:01:02:03”, “00:09:00:02”,24) * you get the idea* that make image management tasks a snap. The demo will work fine for this purpose, let me know if you would like my script.
