Suggestion - Flicker Free Indicator

[Paul Leeming]

Hi Red Team,

I had a small idea which should be easy to implement regarding flicker free shutter settings.

Right now, to figure out the right combination of framerate and shutter angle to get a flicker free image, one has to make some calculations or have a cheat sheet handy, and even then not all the relevant shutter angle combinations are currently selectable in Red's options menu.

But how about if we as users had the option to set the local country's power supply Hz (kind of like setting between 50Hz and 59.95Hz in the PVW out menu), after which the right combination of framerate and shutter angle produced a new indication next to the number display, eg. FF (for flicker free), like so (yes, I know the particular combo below isn't valid but it's a visual example only):

This would mean that you could set your framerate, choose normal, relative or syncro shutter, and from there as you cycled through the shutter angles it would display the FF whenever it hit one that matched the flicker rate of your location. After that it would then be easy to use phase and sync to fine tune.

Thoughts?

can you explain the difference between relative and synchro shutter...
btw. great idea...

Normal shutter means the shutter will only listen to the shutter speed setting in the shutter menu. (ie it will try to stay the same exposure time independent of frame rate)

Relative means the shutter will be decided via the shutter speed setting and the frame rate. In this mode it works like a film camera.

Synco means it will listen to the shutter speed setting and then the sync setting so that, for instance, you can dial in a shutter speed that wont conflict with TV monitors refresh rates.
