Operating Instructions
TVT-S8S Tobin Video Transfer
Basic Operation
Turn on the power with the switch on the right rear of
the TVT-S8S. Check that the left-hand switch is in the "Peak
Auto" position, the knob to the right of it is in the upper "Auto"
position or pointing towards the right, and the right-hand rotary
switch is in the "Normal Speed" position.
(Note: see page 9 for identification of the items on the
front panel.)
Switch the unit to "Still" and note that there are no hairs
or lint visible in the picture on the underscanned video monitor.
If there are any, swing open the film gate and brush or blow out
the hairs. Switch back to "Stop" and close the film gate.

reel hub with the spokes in the reel spindle. If the reel is correctly prepared, the perforations
(sprocket holes) in the film will be towards you, with the emulsion side (the side with the
picture) facing to the right, while the film is hanging down from the right-hand side of the reel.
There should be about 4 feet (1.25m) of leader before the first picture. If any of this is not the
case, return the film reel to the preparation department for correction.
If the leading edge of the film is mangled, trim it straight across in between perforations
and make extremely small bevels on the corners with scissors, if the film preparation
department hasn't already done so. If it is bent or curled, flatten it.
Set the Speed knob to 0.5 or half speed. Switch to "Forward". While constantly holding
down the "Push" lever with your left hand, feed the film into the upper channel with your right
hand.
NOTE: There are two clear plastic windows below the film gate area. You should be
able to see the white leader pass straight down past the left hand window. If it jams and starts to
bunch up, immediately stop and switch to Reverse to back the film out for repair or flattening.
NOTE: After the film is seen to go straight down past the left hand window, a couple of

Check that the film is in fact Super-8. If it
is magnetic sound film, the film itself (but not
necessarily the white leader) will have a brown
stripe on each edge, on the side facing to the left.
Super-8 film has small sprocket holes and
normally comes on a reel with a 1/2" (12.7mm)
diameter center hole. Regular-8 film has larger
sprocket holes and normally comes on a reel with a
5/16" (8mm) diameter center hole.

Note that while running in reverse you will likely get blurring or travel ghost, as the shuttering is optimized for running forward. Start the video recorder. Switch the TVT-S8S to “Forward” and you will be recording the film on video.

Plug the TVT-S8S into a source of 100 to 240 volts AC (alternating current) at 50 or 60 Hz (Hertz, or cycles per second.) For safety and to minimize electrical interference the third wire should be grounded (earthed.) Turning on the unit will cause the footage counter to light...

    There should be at least 4 feet of leader in good condition on the start for proper threading of the TVT-S8S, and enough leader on the end to thread the film cleaning device. Torn film sprocket holes and crooked splices should be removed to prevent transfer problems.
  • Page 5: Exposure Correction

    NOTE: The multiple bends in the film path of the TVT-S8S puts greater demands on the integrity of cement splices. If they are weak owing to using old cement, or not being fully scraped, these are more likely to pop apart than in most silent equipment with a simpler path.
  • Page 6: Theory Of Operation

    For critical transfer for fussy customers who are willing to pay extra, the brightness can also be set fully manually. This latter option usually means that the video must be edited later, to remove the overlap when starting and stopping the TVT-S8S for each brightness correction. Theory of Operation The conventional means of film to video transfer uses a projector with a specific number of shutter blades, attached to the mechanism and rotating with it.

    See the Installation section above. Other Information The TVT-S8S has a “Mechanism Hours” timer to measure how long the main drive motor and the mechanism have been running. This only advances in the Forward and Reverse modes.
