shooting 50p
Obvious question, when shooting 50p for a PAL project is the effective shutter speed 1/50th sec or lis it less to allow vrt time to lay down extra frames?
How long does it take the recorder to laydown the padded frames, and does this have an effect on exposure time?
Presumably this is in done in a buffer to keep slected frame rate constant and smooth while extra frames are added?Mike Brennan

Mike:
The VariCam when shooting at any given frame rate, the camera has no direct relationship to the tape section. So, if you shoot at 50fps, the camera is acquiring at 50fps, the shutter can be adjusted from OFF (max of 350 degrees) down to minimum of 3 degrees. 50 fps at 350 degrees equates to a shutter time of 19.4444ms, very close to the full 20ms of 50fps. The pulldown cadence buffering prior to recording is done after capture in RAM and has no effect upon image capture in the camera.
