It may be worth noting that the EPIC camera we were using had an HDMI output. I actually wound up pointing a cheap webcam at one of the monitors and feeding that into my app. Not ideal, but sufficient for the task at hand.

<p>I need to get a live video stream from a RED camera into a proprietary app running under OSX (though I can switch to Windows if necessary). I'm unable to find any information about getting a live preview from a RED camera.</p>

<p>We have a video shoot tomorrow. The video is going to be shown in a 3D environment, and we need to make sure that the actors' eyeline, etc. is correct for their position within the simulation. Note that we're recording 2D video, not 3D - the flat video will be placed on a plane within a 3D environment.</p>

<p>Preview resolution is unimportant - 320x200 would work fine for this stage of production.</p>

<p>The best solution I have at the moment is to tape a webcam to the side of the RED and use that as the input to my application. That will work, but I don't think the camera owner will be thrilled with my use of duct tape.</p>

<p>My app works fine with a webcam interface, but somehow I doubt that RED has something like that available.</p>

<p>HELP.</p>

<p>(In case it matters, the application is a Unity3D app running under OSX. Video is being displayed within a 3D room on an Oculus Rift.)</p>

I need to get a live video stream from a RED camera into a proprietary app running under OSX (though I can switch to Windows if necessary). I'm unable to find any information about getting a live preview from a RED camera.
