As I post this I am using a really crappy Composite to USB adaptor that is very buggy with some free video capture software to record all my late grandma's VHS-C tapes to my PC. Most of them are of me and my siblings as small children.
There is one of my opening my Sega Mega drive Christmas 1994 <3.
It is taking an absolute age to copy them all over, including finding software that even works.
I am using a free trial of Movavi Video Editor and blasting through the tapes before the 7 day trial expires!
Even in my 30s I am mesmerised at the VHS-C adaptor cassette that turns the camcorder tapes into full sized ones!
I've been doing pretty much the same thing recently. I bought the "Elgato Video Capture" USB 2.0 device for 80 quid yes it is called that generic sounding name. It comes with drivers for Windows and its own software which was really easy to use but I then also had a sniff around the free OBS software instead and this works great with this capture device. One thing OBS does is it allows you to capture at 50hz and deinterlace the video, which is what all my dads miniDV videos are recorded in. With the default software all the captures were at 25hz and I could tell the frame rate was half what it was if they were played on the camcorder, so OBS basically went beyond what the default software is allowed to do with the hardware, and shows the hardware itself is capable of more.
In summary, give the OBS software a go and see if it can get the most out of your capture device. OBS can also use your gpu to hardware encode on the fly, so you don't end up with massive files you have to compress later.
BTW, the only reason I bought the Elgato was that I know I have one of those really cheap USB capture devices around here somewhere, but I can't find it for the life of me, so went and got the Elgato. But I can tell you the quality is quite a lot better than with the cheap one from when I used it before. Though it would have been nice if I could have tried it with OBS as well, to see if it made the best of it.
Edit: Plus if you do edit to do any editing as well then Kdenlive or Da Vinci Reslove are free. You may even be able to capture directly with these same as OBS.
