What does it mean for time code to be in phase with video?
When time code is recorded on video tape, it must be synchronous with the video signal, meaning that the beginning of each time code word must coincide with the beginning of the video frame it describes. This is essential for video editing. Each word of time code is made up of 80 bits, numbered from 00 to 79. Time code is phased properly with video when the end of bit 79 of time code lines up with field 1 line 5 of video (± 1 line).
How can the SA-1 tell me if time code is properly aligned with video?
If the video phase LED blinks mostly on, time code is out of phase; if it blinks mostly off, time code is drifting. In addition, the 8 digit display indicates which of the 80 bits lines up with video field 1, line 5. Properly phased time code should indicate 00 or 79; drifting time code will indicate a changing bit number.
