    If you are currently an owner of the Evertz 4015 Film footage Encoder, you will find 4015 that much of the installation is similar for the 4025. Items that are of particular not for 4015 users are marked with the following symbol in the margin.
  • Page 21 GEN LOCK: In order to ensure that the timecode to video relationship is fixed, according to SMPTE/EBU specifications, a video reference must be supplied to the 4025 Film Footage Encoder. Normally, the gen lock signal is the program video out from the telecine, onto which the vertical interval time code (VITC) is being applied.

WHITE FLAG: A white pulse recorded on one or more lines in the vertical interval on the first video field of a new picture. This pulse is normally used on 24 frame per second transfers to NTSC video that will end up on video disc recorders.
