Diagonal torn framelines appearing on Duo Framliner generator when used with Arricam ST camera tap

20 years old. Gear and prices may have changed since.

What the thread found

  • Torn diagonal framelines appeared on a Duo Framliner monitor when paired with an Arricam ST camera tap, becoming worse when the lens iris opened or brightness increased on the monitor
  • The frameline distortion only disappeared when the lens iris and monitor brightness were both closed down significantly
  • The same Duo Framliner generator worked without problems when connected to an Arricam LT, Movicam Compact MK2, Arricam 435 Extreme, and SR3 cameras
  • The root cause was determined to be a faulty video tap on the specific Arricam ST camera that was used
  • A camera-integrated frameline generator can be used as an alternative output to transmit framelines to video village instead of relying on an external monitor generator

Depends on

  • The troubleshooting was limited by not discovering the internal camera frameline generator option until after the shoot
  • The issue occurred on a production shoot in a dark library setting where framelines were necessary for framing Super 35 format at 2.35 aspect ratio
  • No resolution was attempted with the TB-6 monitor's internal frameline generator switched off during the actual shoot
