Question: I have regular 8mm movie film, not super 8mm. Will this device still be effective?
Document: The unit dose work but rather difficult to align projector and camera/camcorder for proper transfers.The unit comes with instructions and an alignment sheet however moving the 8mm or slide projector and camera or camcorder to proper focal distances/angels is tricky. I shot some film using the unit then shot the same footage using a standard movie screen the resulting video quality looked the same no improvement using the unit.
I purchased this product because I located some decades old super 8 and 8 mm film reels in my attic and wanted to get them into a format that could be more easily viewed than a projector with bulbs that blow so fast. I also intend to edit and add still photos taken through the years after putting the videos into chronological order and sharing with family. I researched having a company do it, but the cost of $8 per 50' of film and having over 3,000 feet made that too costly.
Using the box it came in as an extra height stand, I put the mirrored screen on top the diagram for positioning. I moved my old 8mm movie projector until the image filled the screen, focused, rewound the movie I had been using to do set up. Then I set up my point and shoot digital camera to do video and set it to focus on the screen and started both it and the projector.
Good idea for the device but the projector and camera are not in sync. The camera that I have cannot be adjusted to the low frame rate and it picks up the flickering of the film. The Film Transfer System device is well made but just didn't work for me.
This allows for the best head on shot (to minimize the keystone - not quick square - output on your camera). It also reduces the flickering and bright spots to a more subdued viewable and recordable output.This item may work very well for still slides without that flicker. But I did not have good luck with it trying to record my reel film images for editing and sharing on the computer.
The transfer system works well to help transfer my 8mm film to digital format. It's very easy to use and it's a great "poor man's" alternative to the expensive WorkPrinter systems.
The product description lead me to believe that all I needed was a  digital video camera and a tripod to work this product. But you also need your own Super 8 projector. I had to send it back unfortunately.
My family has a lot of old super 8 movies laying around which we have never watched. I wanted to have them digitalized so that we can enjoy them. I did some researching before I found this "box", ordered it and it came within a few days. I brought it home for Christmas and it was amazingly simple.
This arrived in very good conditon and it has worked just like it is supposed to. I have transferred my super 8 movies using my digital camera and they look great. It came with a template which I used and everything lined up perfect. It is nice that the whole process could be accomplished on a card table.
It is easy to set it up and takes little effort or technical knowledge. Just adjust the camera so it captures the frame correctly and hit 'record'. That simple!I only converted super 8 movies but next time I go home I will try it with slides and old pictures.
Answer: I think it may be projector specific.  This did work OK with my Super 8 projector, but my regular 8 mm projector would not focus at a close enough distance for the image to fit this screen.
