Watec 910XH – One way to make the 910HX resemble a progressive scan camera (i.e., noninterlaced video) is to set the exposure setting at “2x”. This setting causes each field to be exposed for the full 0.0333 seconds of the frame, with both the top and bottom field being exposed simultaneously. This is very different from the exposure when set to “1x”, at which each field is exposed for only half of the frame time. This also increases the sensitivity of the camera. Further, it results in an adjustment in the interpretation of the inserted times. The time adjustments have been thoroughly
investigated by Gerhard Dangl, Bob Anderson, and others. (See http://www.dangl.at/ausruest/vid_tim/vid_tim1.htm#correction ) Note that, due to the differences of this camera, it needs an adjustment to the time inserted by the VTI even when on the 1x setting.
Note that a 2-frame integration occurs when it is set to “4x” exposure, not at “2x”.

- Another important point to enhance the accuracy of light measurement with the Watec 910 cameras: set IRE to 7.5 for NTSC to avoid loss of background brightness. This setting is under the “Adjust” menu. (Mine came from the store with a factory setting of IRE = 0.)
- just a reminder to those using WAT910 cameras, use the camera with Sense-up=OFF and set the integration rate using the Shutter setting.

Another note is that the first 910HX cameras (numery poniżej 1000) were using less sensitive chips compared to the 910BD and the later 910HX cameras
