Flicker Shooting Red in Europe

Recommended Posts

What do you guys think is the best solution for shooting with the Red in Europe and to not get flicker? When shooting 50Hz is it better to adjust frame rate, shutter angle, etc.? What are people doing? What have you done? Thanks all, I appreciate your responses. So informative and helpful.

Hi,

By just using 25Fps/ 172.8 Shutter will solve your problem in most cases, be sure the sound enginneer does the same too, (if you don't recording sound on RED) it will save you some Post production.

The good thing with video cameras is that you can check the flicker . If you are in a place with industrial or home fluorescent lights, try not to use more than 50Fps. They won't exactly flicker but the light will go down and up in periods.

 

I believe by just using Normal operating mode for your shutter will do.

 

Mode: enables one of three following shutter modes. Default selection is Normal.

 

Normal: Shutter Speed is defined exclusively by the Shutter Speed setting.

 

Syncro: Shutter Speed is defined by Shutter Speed, but modified by Syncro setting.

 

Relative: Shutter Speed is defined by Shutter Speed, but modified by the capture fps.

 

To Convert Shutter Speed to Angle Equivalent:

Equivalent Degrees = (Shutter Speed x Frame Rate x 360)

E.g. = (1/48 x 24 x 360) = (8640 / 48) = 180

Shutter Degrees Shutter Degrees

1/32 270 1/120 72

1/48 180 1/192 45

1/50 172.8 1/348 22.5

1/60 144 1/696 11

1/96 90 1/1000 8.6

 

 

To Convert an Angle to an Equivalent Shutter Speed:

Equivalent Shutter = 1 / ( Frame Rate x 360 / Angle )

E.g. = 1/ (24 x 360 / 180) = 1/ (8640 / 180) = 1 / 48

Degrees Shutter Degrees Shutter

270 1/32 72 1/120

180 1/48 45 1/192

172.8 1/50 22.5 1/348

144 1/60 11 1/696

90 1/96 8.6 1/1000

 

I hope this helps.
