- First off your lines are too long. Please make then shorter than 79 characters.
-
- Secondly you are running into the problem of the film being projected at 18
- frames per second, while video is 59.94 fields per second. The video camera is
- even picking up the times that the screen is black (while the film is being
- moved to the next frame and also during the black of the double-bladed shutter).
- So, the film is being projected at a rate equal to 36 fps. Notice that the two
- rates are not the same.
-
- The only correct way is to use professional services that have equipment that
- will pull the film correctly through the transport, in sync with the recording
- system.
-
- Personally these home transfer methods are for the birds. But professional
- services are going to cost an arm and a leg.
