Digital Movie Remastering – Flicker

I’ve been bombarded with questions today asking me about remastering of movies shot digitally.  There are several issues when delivering a movie shot in digital to the consumer whether using DVD, Blu-ray or OTT streaming.  These issues become greatly amplified when you start moving into the Ultra HD realm, especially with the various color space issues and HDR formats.  With the consumer TV market HDR and UHD are not standard.  Color space can be DCI-P3 or REC2020.  HDR standards include HDR-10, DolbyVision, HLG and variations that TV manufacturers are implementing.    Even within a single manufacturer you have sets that can generate different levels of brightness in HDR.   You can have sets that max out at 500nits and others at 1,000 nits.  When viewing video on the different levels of color and brightness you end up having a different threshold for the Flicker Fusion where the movement causes a visual flicker.  On lower end panels this is much more noticable than higher end panels.  It becomes really obvious when videos shot digitally at 50/60 fps is played back on sets that don’t support the higher frame rate and have to stepped down to 25/30 fps.

When preparing videos and movies to be streamed OTT you can improve the user experience substantially by creating different masters for various platforms from mobile phones to the highest end HDR Ultra HD television.
