My equipment and process to convert 8mm home movies to Blu Ray. Projector is Bell and Howell 471 with all the electrical components removed. I used a Dremel to open up the film gate and cut the frame adjustment rod at an angle for a micro-switch to trigger the Arduino. I tried you use a Hall effects sensor but I couldn’t get it to work right. Replaced the motor with a 10rpm 24v gear motor. It has to run really slow just one frame every 10 seconds. Why? I’ll tell you. Point Grey Blackfly camera with High Dynamic Range. When set in HDR mode the camera cycles thru 4 different shutter speeds each time it’s triggered. When the micro switch is pressed 5v goes to the Arduino GPIO and the script breaks it up into 4 timed signal’s sent to the camera trigger. The result is 4 YUV444 2448 x 2048 uncompressed tif images.
Now for the processing. Photomatix Pro batch process for the 4 image fusion to one HDR. IrfanView to convert to png. VirtualDub to create the avi. VirtualDub filters Film Dirt Cleaner then Deshaker. Avisynth to crop it. Finally and maybe the most important part is VideoFred’s Avisynth script. Maybe a little crop after that.
Math – 50’ 8mm film is about 3500 14mb frames X 4 = 200Gb convert HDR tif’s to png add 50Gb, compile to avi 50gb safe copy after Cleaner and Deshaker 50 more Gb’s, Fred script 50Gbs. That’s if everything goes right so figure 1Tb per film.
So many people made this possible I don’t even know where to start but most of them hang around doom9.org ---
