EVF Refresh rate

[Matt Redmond]

What are the refresh rates for the EVF?

For us it seems as if the rate is a bit low (a bit like sitting in front of a computer monitor set at 60Hz). So while the picture looks fantastic, the eye does get a bit strained from the slight flicker.

Assuming that you are shooting 25 fps, the default refresh rate would be 50 fps. At 24 fps it would be at 48 fps. You can change the refresh to a fixed rate of 60 fps in the MONITOR menu - change from SYNC to FIXED. This setting only affects the EVF output.

The OPEN GATE function can also affect EVF display. That's where the sensor frame rate is over clocked 2x relative to the recorded frame rate. For example at 24 fps recording the sensor captures at 48 fps, the EVF displays at 48 fps (or 60 depending on your setting above) but the recording to digital media is still 24. This setting affects all the outputs.

Stuart, newbie here, can you enlighten me on this OPEN GATE function? capturing at 48 but recording at 24? What is this different, say from a normal function, if any?

Let's put it this way. With a rotary shutter mirror in a cine camera, when the mirror is in the light path you can see, and when it's not the film can "see" and gets exposed. With the open gate option on the RED you can see during both states since the sensor is both the shutter and the "film". You'll then be viewing "48fps" which is supposed to be less straining to the eyes, at the cost of not "only" seeing the recorded material (may be a hindrance if you're shooting something that might last less than a frame since you are also monitoring what the camera will not record!). Does this help?
