Converting Quicktime Video Screen Capture to smaller file sizes

[niceties55]

I have about 10 longer Quicktime Video Screen Capture files which are massive (10+GB). I was wondering if there is an app or software that I can bulk shrink the file sizes and/or convert to H.264?

I have google searched for this but most of the search results that I get are junk spammy software.
I am either looking for a reputable paid software or a good freeware/open source software.

I am using Mac OS Catalina

Thanks a lot!

Have a try with Handbrake.

I have an h264 mp4 file that comes out at 184mb. With Handbrake, I chose the fast 720p setting and that gave me a 65mb file. I then used the fast 480p setting and that gave me a 52mb file.
