Filming high FPS in anamorphic 2x with V-Raptor (8K VV)

[Michael Tebinka]

Hi all,

I'm trying to find some reliable information ahead of a camera rental (thinking of the V-Raptor 8K VV).
We have a production where we intend to use 2x full frame anamorphic lenses and the information I am trying to find is what the maximum fps you can squeeze out of this camera while maintaining anamorphic capture. As we are filming with 2x anamorphic for a 16:9 delivery it is my understanding we are looking at a 1:1 capture to get us closest to a 16:9 delivery (with some horisontal crop).

I am aware that we crop the sensor itself when filming at lower resolutions and higher fps. This would also change the look of the image as we crop in on the anamorphic lens.

The information I can't find is at what resolutions does the camera support 1:1 capture? And what is the max fps at each resolution?

Can someone please verify this information?

Thank you in advance

If you shoot ”8k 1:1” its 120fps max as the readit speed is capped by the hieght of the sensor used. ”7k 1:1” will give you 137fps if I remember correctly.

The naming of the resolutions is a bit odd. But 8k refer to full hieght 7k to 7/8 of full height and so on.

Does it support lower resolutions and thus higher frame rates at 1:1 ratio?

Yes basically, full sensor height 120fps half sensor height (4k) twice the speed, 240fps.

Click on the resolution tab on Philfx tool to see all the available resolutions for raptor. Basically there is 8 different 1:1 resolutions to choose from, always strive to use biggest sensor area possible. Like do not shoot 2k 1:1 if the frame rate wanted does not demand it as picture quality goes down with less sensor used.

Heh. I'll do you one better because I made pretty charts, stickied in this topic right at top:

In short: Max framerate for Red V raptor = ((120fps / 4320) x your chosen frame height in pixels))

It’s worth noting that once you drop below 6K resolutions the camera won’t de-squeeze for you. You’ll need to use the SmallHD tools on the DSMC3 monitor to stretch the image manually. The same will need to be done to the AC/Village monitors for proper viewing.

It isn’t awful, but you should plan on this workflow if you’re going to push the FPS past what 6K can do.
