Now that your camera and sensor are paired, you are ready to click the Record tab and begin recording your volumetric video! When you are ready to record, do not change your video camera resolution or focal length. This will invalidate the camera pairing that you just generated.
However you can change any other camera settings (exposure, framerate, white balance, ISO etc.) or any of your sensor settings including the Depth or Color Modes.
You Can Change Your Exposure and Sensor Settings
You can change any of your camera exposure settings including exposure, framerate, shutter speed, ISO, white balance.
You can change all of your sensor settings including Depth Mode, Color Mode, Exposure Parameters.
You cannot change your zoom, your video resolution, or your rig.
If you have already generated a successful Camera Pairing and your are using a secure camera/sensor rig, you can import this previously generated pairing into a new Depthkit project. You should only use an existing Camera Pairing if your camera/sensor rig is mounted in the same configuration, you are using the same lens, and the camera resolution, zoom, and focal length are the same.
To import a Camera Pairing, go to the Depthkit menu under File and select Import Camera Pairing.
Locate your existing Depthkit Cinema project and select the parent project directory folder that contains your camera pairing data. This will automatically pull in your existing samples into your new project.
Overwriting a Camera Pairing
If you import a Camera Pairing into a project that already contains a Camera Pairing, it will ask if you want to overwrite the data. If you opt to overwrite, you cannot undo this action.
Since you are recording high resolution video on your camera, the sensor video will still be needed for synchronizing your footage. When you process your footage, you will use both of these videos to synchronize each take.
Don't forget to record a clap, or slate, for each take as well! This will be needed to the synchronization step up next.
More on this this stage in Processing your cinema capture.
Incompatibility with 15Hz Recordings
If you paired your camera and depth sensor using either 3072p 15Hz color resolution or 1024x1024 15Hz depth mode, you will need to change your stream configuration to settings that do not record at 15Hz. If you record your takes in 15Hz, you will not be able to synchronize the sensor footage to the camera footage. See more on synchronizing your takes.
While our recommendation is to pair your camera and depth sensor at 3072p and 1024x1024 for maximum frame overlap with your camera, recording requires different settings. For best performance while recording with the Depthkit Cinema workflow, set your color resolution to 1080p and your depth mode to 640x576 Narrow raw and increase your resolution if your hardware can support it.
At Depthkit, we always recommend capturing a test take to verify your Camera Pairing before production. It doesn't have to be scientific, simply grab a matte object with some defining features and make a quick recording while moving the object around the 3D space. In the example below, we grabbed a cardboard box with some colorful tape and walked around the capture area. The goal here is to verify that the box depth data and color are properly aligned in all areas of the frame.
To check this take, import the camera capture and synchronize the sensor and color footage as described in Processing your Cinema Capture.
