A Prime Color camera can be equipped with either the 12mm F#1.8 lens or the 6mm F#1.6 lens. The 12mm lens is zoomed in more and is more suitable for capturing at longer ranges. On the other hand, the 6mm lens has a larger field of view and is more suitable for capturing at a wider angle. Both lenses have adjustable f-stop and focus settings, which needs to be optimized for capture:
Note for 6mm F#1.6 lens: When capturing 1080p images with 6mm F#1.6 lens, you may see vignetting in each corner of the captured frames due to imager size limitations.
Detecting Dropped 2D Frames
Every 2D frame drops are logged under the Status Log panel, and it can also be identified in the Devices pane. It will be indicated with a warning sign next to the corresponding camera. You may see a few frame drops when booting up the system or when switching between Live and Edit modes; however, this should only occur just momentarily. If the system continues to drop 2D frames, that indicates there is a problem with receiving the camera data. If this is happening with Prime Color cameras, try lowering down the bit-rate, and if the system stops dropping frames, that means there wasn’t enough bandwidth availability. To use the cameras in a higher bit-rate setting, you will need to properly balance out the load within the available network bandwidth.
Note: Due to the current architecture of our bug reporting in Motive, a single color camera will not display dropped frame messages. If you need these messages you will need to either connect another camera or an eSync into the system.
The eStrobe is designed to receive exposure signals from a Prime Color camera via RCA cable connection and synchronize its illuminations to the camera exposures. Depending on the frame rate of the camera system, the eStrobe will vary its illumination frequency, and it will also vary its percent duty cycle depending on the exposure length. Multiple eStrobes can be daisy-chained in series by relaying the sync signal from the output port to the input port of another as shown in the diagram.
The amount of power drawn by each eStrobe will vary depending on the system frame rate as well as the length of camera exposures, because the eStrobe is designed to vary its illumination rate and percent duty cycle depending on those settings.
At maximum, one eStrobe can draw up to 240 Watts of power. A typical 110V wall outlet outputs 110V @ 15A; which totals up to 1650W of power. Also, there may be other factors such as restrictions from the surge protector or extension cords that are used. Therefore, in general, we recommend connecting no more than five eStrobes onto a single power source.
When capturing high-speed videos, brightness of the captured frames will vary depending on which type of ambient light source is used.
