There are a couple '8mm' tape formats.
My suggestion:
Put a saved search on kijiji (or craiglist or whatever) for a DIGITAL8 camcorder. You'll find one for under $100. These cams are backward compatible to the 8mm and hi-8 analogue formats. They will play those analog tapes and output digital stream (DV) over Firewire. The harder part is now getting a computer that will take the firewire (you may have an old laptop -- macs had them until like 08 -- or get a firewire-to-usb2.0 cable or thunderbolt to firewire adapter on amazon). Modern imovie/premiere will gladly accept the DV stream/control the camcorder.

Modern computers with thunderbolt will take a converted fw stream without any problem. I am using several old fw400 sound interfaces with a string of adapters without any problems, on both mac and pc. The mac laptop has tb built in, for my workstation pc (Windows 10) I bought a PCI Express io adapter for 30 euro. Works perfectly.
I concur, it's the best solution for analog Video-8 tapes. Buy a Digital-8 camcorder with DV. You may get a better picture with some kind of bespoke high-end rig with rebuilt camcorders and studio digitizing equipment, but for mere mortals, it's the best solution.
I can only add, that for me it worked best to capture the tape all in one go, and not try to start-stop the camera with DV control. Be it deteriorating tapes or whatever the cause, but the capture software had problems resuming the camera if it was ever paused.
Agreed - just letting the tape run for the duration is best. It's a shame that it has to be done in real-time. I don't see why (from a technical standpoint) the process couldn't be done at a faster speed. It's just that the hardware isn't made for it and there's not market. The analog-to-digital processing could be done by a faster chip or even software at this point. Something akin to the high-speed dubbing of analogue audio cassettes.
And it leads to that other challenge worth mentioning: Even though DV is technically a lossy format, it results in really large files.
Funny... I've been contemplating a SLOWER than realtime tape digitizer. Something that would make multiple passes and reconstruct the magnetic domains on the tape with very high certainty.
Yep. Especially a hacked VCR could be made to do this. If one taps the data from the spinning head directly, instead of relying on the VCR to process it into a proper composite signal, I'd say it's even realistic to do this.
Just run the tape at half or a quarter of the speed. The spinning helical head should still produce data. Then it's a matter of assembling it in software.
