RE:Vision Effects Unveils DEFlicker v2

RE:Vision Effects, Inc., the effects plug-in developer, has introduced DEFlicker v2, a major upgrade to its solution to problematic high frame rate and timelapse footage.

DEFlicker takes control of all things that flicker whether you shoot with very high-speed shutter or at very low video frame rates (timelapses). Version 2 provides additional and enhanced tools for correcting high-speed shutter artifacts, timelapse flicker and now comes with 4 plug-ins:

  • HighSpeed: High-speed shutter and high frame rate elements tend to exhibit strobing caused by lighting systems. New in DEFlicker v2 are tools for managing the Alpha Channel for green screen VFX shots. Also added is improved noise reduction and a simplified method for removing the flicker quickly. Now users can enter the frames-per-second of the shot, and the system frequency for their region (50 or 60 Hz) and DEFlicker takes care of the rest.
  • Timelapse: Your solution to handle flicker of image sequences with a lot of motion discontinuities. New features include improvement of render speed for sequences over 4K and better handling of large color and lighting shifts. It now also properly deals with over-range values.
  • Auto-Levels: Extended timelapse scenes often suffer from fluctuation in color and levels when shot using automatic exposure. DEFlicker already allows you to display graphically the variation over time and replace missing frames in the sequence. In v2, new methods of fixing or replacing bad or damaged frames are implemented.
  • Rolling Bands: New in v2, the Rolling Bands plug-in can be used in conjunction with the High-Speed plug-in or by itself. It allows you to model and attenuate those annoying dark bands primarily caused by lighting and rolling shutter speed time synchronization issues. Rolling Bands provide interactive ways to model the rolling bands height, the distance between bands, and the speed of roll. It also provides fine band feathering options to match the source video transition from lighter to darker. Temporal processing takes into account the rolling bands speed.

All plug-ins will see better handling of linear versus gamma encoded sources (now automatic in AE, matches project settings) and v2 should load v1 based projects without issues.
