Convert .dv files to .mp4

I have a 10GB file that is .dv format. It is a conglomeration of videos from 1998 (family stuff) that I'd like to parse into smaller cuts for each event. It's a conversion from old tapes taken at the time and I no longer have the original tapes. I think I can do it on Win10 if I can just get it converted into .mp4.
I've looked online and there seem to be some fishy 'free' sites but there are file size maximums that I exceed. I didn't want to pay a ton just to convert this one file...
Thoughts or suggestions on safe conversion sites that can handle that size?

use VLC to convert overnight while you sleep?

Take a look at the free version of Any Video Converter. I prefer to keep my files on my computer, so I use desktop software. AVC is rated highly and I have used the program for a couple of years with great results.

Handbreak should work, I’ve been quite pleased with the results, and conversion speed. Our IT Dept installed on my company laptop, so they trust it. Plus it’s free.
