I built a Gugusse Roller a few years ago for scanning 8/super8/16 reels, and it's been an absolute workhorse. So Denis's site isn't hugged to death, here's a link to his YouTube:

It's a bit slower, but it's in active development.

I wanted to scan some old family super-8 movies. You can buy film scanners that will do the job on amazon. The only problem seems to be that they will encode the video, but nobody seems to convert the magnetic audio track. EDIT: example - https://www.amazon.com/dp/B0CN93JSX6

I used a similar scanner from Amazon for some 8mm. It mostly worked, but I ultimately decided it was a better use of my time to have the film professionally digitized.

I would still love to figure out a good process to clean and upscale the video. I tried Topaz a while back, but it didn't seem suited for some of the artifacts in old, jittery film.

Various sources list the Canon 1000D shutter life expectancy at between 25,000 and 100,000 activations. If the 8mm film is 16 frames per second, then this setup should be able to capture between 26 to 104 minutes of film before consuming the expected lifespan of the camera shutter. Edit: Changed math from 24 frames per second to 16 fps to reflect the 8mm film fps standard playback speed of 16 fps.

The older Standard 8 format used 16 frames per second. Super 8 is 18 or 24 fps

Do you have a service or an individual you’d recommend? My fiancé’s mom has some old film from their childhood that is meaningful to them, and we’re considering gifting them some digitization services if we can find someone to help.

The quality is probably not as good but my father got fairly decent results filming directly with his digital camera the projection of the super8 film on a screen (obviously in the dark).

The added bonus is he would grab the sound of the projector which add a bit to the vintage touch.

Ah, so there's no shutter at all then? As in, the mirror itself forms the shutter? For some reason I figured there were both. Makes sense I guess.

No, in most* cameras there's still a shutter behind the mirror, the mirror can't move that fast so would limit the top shutter speed too much. *The Ihagee Exa is the only one I know of that used a mirror guillotine shutter.

I think (some? most?) motion picture cameras used a rotating mirror for shutter.

I used legacybox. I was wary of shipping off something so irreplaceable, but it came back safe and sound.

This is the good answer. Also to get even better results you can project on a specific small screen using a mirror so you have an even better image. Due to 8mm low quality there is no gain from scanning.

I've used Kodakdigitizing.com

It was costly (but the price per roll went down if you have a number of rolls) but the mailer they sent was high quality. I never had any worries about my film being damaged in transit.

Correct, it’s like a mirrored fan blade and rotates continuously.

Ironically, with mirror reflex system what you see through the finder are precisely the moments not captured on film. Very quick events, muzzle flashes for example, can be missed entirely.

Notably, some Bolex cameras (and others?) used a beam splitter system where you do see what the film sees, with no flicker from the shutter. The tradeoff is a dimmer image in the finder, and you’d need to overexpose to compensate for the lost light.
