TVT-D8C Film Format Changeover
Claw Change: Move the Claw lever all the way up to Super-8 to center it for super-8 film.
Move the claw lever all the way down to Regular-8 to center it for regular-8 film.
Feed Reel Spindle Change: the Super-8 reel spindle adapter slides on and off. S8 film uses the
1/2" (12.7mm) spindle and R8 film reels have the 5/16" (8mm) size hole. (The “wrong” spindle
can be installed to suit film that is wound on the wrong type non-standard reel.) If available, an
original black plastic spindle adapter will be provided. If not available, an alternative adapter
will be furnished and this may require a rubber reel retainer to prevent the reel from falling off.
Magnification Change: The effects of this and the following adjustments should be judged on
your underscanned monitor. The lens can be removed by fully unscrewing the Magnification
adjusting knob. An internal spring presses the lens against the adjustment. For Super-8 film, the
end of the lens with the retaining ring should face the film. For regular-8 film, the end of the
lens with the retaining ring should face the camera. For Super-8, adjust the Magnification screw
so the right end of the lens is protruding from the lens holder by about .2 inches or about 5mm.
For regular 8, reverse the lens end for end so the retaining ring is on the left, and slide the lens
so the right end extends only about .12 inches or about 3mm past the right side of the lens
holder. (When adjusting the TVT-D8C to match the aperture of a particular film camera, this
setting can be modified. Moving the lens to the left will further magnify the film (zoom in);
moving it right will reduce the size (zoom out). If you “zoom in” too much you will cut off
people’s heads and feet more often. If you “zoom out” too much you will have to change the
Framing Adjustment more frequently while working, and you are more likely to see and deal
with hairs and dirt around the edges of the camera’s filming aperture.)
Note: the following steps use the 7/64" Allen hex driver, with camera cover removed, and you
can best see what is happening if the room lights are very dim.
Centering Change: Run the film to be copied to a few feet past the end of the head leader. Pick
a spot with lots of fine detail or that is grainy, for easier focusing (below). If the film frame is in
