Sony F3 and F65 (using camera's video output for sync)

Many cameras, notably the Sony cameras, output a video signal which is intended for synchronization with camera acquisition.  On the F3 and F65 (and others) the output is labelled HD-Y, which is the luminance channel of a component video signal.  This contains the trilevel synchronization signal. 


In order for the video output to be used for synchronization, the output frame rate must match the acquisition frame rate without any telecine conversion.  The F3 and F65 output a 23.976PsF signal.  PsF stands for "progressive segmented frame," and from a signaling standpoint appears to the Time Filter as a 47.952 field-per-second signal.  To use this signal, set the Time Filter's synchronization mode to VIDEO, and set the video sync mode to SYNC FRAME.  This will cause the Time Filter Controller to synchronize on each full frame rather on each field, so the output rate will display as 23.98 Hz, matching the acquisition rate.

On the F3, the output must be set to HD-Y in the camera's menu. 

Power is typically provided by using a standard P-tap cable.  On the F65, if the camera is supplied with 24V power, the 3-pin Fischer power output on the camera can be used with Tessive cable part # TCAB-RS.  

On the F65, the phase delay at full resolution for calibration to center of frame is typically -14.2 ms.  The rolling shutter readout of the F65 takes 13.9 ms from top to bottom of the frame.  As always, the phase delay should be measured with the Calibration Wand to ensure proper operation.
