Can't achieve 60 fps rapid in 4K

[alan morgan]

Sorry didn't locate similar thread here. Any suggestions on subj?

Hi Alan,
Are you trying to overcrank to 60 FPS in 4K? If that is the case, you will have to switch from 4K to 3K if you want to shoot 60 FPS. You can't shoot 60fps in 4K as far as I know.
You will also have to shoot 2:1 as I think that 16:9 maxes out at 50fps. Hope that helps.

Hi Jason! Thanks for the instant response!

I try to shoot 16:9 4K varispeed, but all i can get is 30 FPS and not higher! With any timebase. I can't get how is that.

Max framerates for the Red One are:

4K, any mode - 30fps
3K 16:9 - 50fps
3K 2:1 - 60fps
2K 16:9 - 100fps
2K 2:1 - 120fps

It's not possible to shoot 4K above 30fps...

HTH,
Dom.

Thanks, Dominic! Somehow i thought i seen 60FPS@4K in manual, but maybe i mistaken.

You could shoot 4K at 30fps with higher shutter speed to eliminate motion blur, then use Shake to retime to 60fps, then add motion blur at final step. The results would probably be amazing if done properly.

The sensor can operate at 60Hz at 4K, however this is only for the monitor path - you get it by enabling OPEN GATE for the viewfinder. You're still only recording 30P at most.

Remember that the camera is capable of "stopping" fast action 30 times per second in 4K progressive resolution with enough light and fast enough shutter speeds. Unless you are filming something like moves in unpredictable motion (non-linear) faster than that, Shake's Optical flow technology can interpolate the in-between frames with extreme precision to the point no one would know the original footage wasn't shot at 60fps. The trick is using fast shutter speed and adding the appropriate (for your delivery frame rate) motion blur in post.
