Page 12: Detailed Description
Detailed Description Video Processing The MVPHD-24 uses a 3 dimensional COMB filter for the composite input, and a motion compensated processor to de- interlace all interlaced video formats to full progressive video. All processing is performed on the progressive images at 10 bit resolution per channel. - Page 13 HDMI Input The HDMI input supports video formats from SD to HD resolutions and graphic formats up to 1920x1080p. VGA Input The VGA input accepts standard VGA resolutions up to 1920x1080p. Still Image Buffers The MVPHD-24 has four still image buffers which may be selected as input sources. Each image is stored in FLASH memory, and automatically reloaded on power-up.
- Page 14 Primary Output Mode The MVPHD-24 is not capable of producing perfect images on all outputs simultaneously. Therefore the primary output mode is used to select the desired output that is most important. The other outputs may continue to work but the quality may be degraded. Output Frame Rate and Formats All output signals from the MVPHD-24 operate at the chosen frame rate (23.976, 24.000, 25.000, 29.970, or 30.000 Fps).

Page 45: Chapter 4 - Overview Of 24 Fps Video Playback
Chapter 4 Overview of 24 Fps Video Playback Chapter 4 – Overview of 24 Fps Video Playback Introduction There are three factors that affect the camera’s ability to film a television monitor; the frame rates of the camera and monitor, the phase of the camera’s shutter and the monitor, and the shutter angle of the camera. What follows is a simplified description of these factors. -
Page 46: Shutter Phase
Shutter Phase Once the video’s frame rate is made equal to the camera’s frame rate, then the phases of the camera’s shutter and the monitor become important. It will be assumed that the camera’s shutter is open 50% of the time and closed the other 50%. - Page 47 SCA NNED VIDEO RESULTING SHUTTER IMA GES PICTURE TIME BOTTOM OPEN BOTTOM BOTTOM CLOSED Figure 4-3. Example of shutter angle > 180 degrees. TIME BOTTOM OPEN BOTTOM BOTTOM CLOSED Figure 4-4. Example of shutter angle < 180 degrees. In Figure 4-3, the shutter angle is greater than 180 degrees. As can be seen from this example, a small portion of the image is seen by the film twice, double exposing it and creating a light horizontal band in the picture.
- Page 48 TIME OPEN BOTTOM BOTTOM CLOSED BOTTOM BLANKING INTERVAL Figure 4-5. Example of shutter angle > 180 degrees, with 0 degrees of shutter phase. Figure 4-5 demonstrates the condition when the shutter and the image are in alignment. Even though the shutter angle is greater than 180 degrees, the area of the image that would be double exposed is now blanked.

Page 51: Synchronization
Synchronization For proper setup, the Camera(s) and the television monitor(s) must be synchronized. This is typical done by supplying a master reference to all the cameras and video equipment used. MVPHD-24 as Master Reference MVPHD-24 The MVPHD-24 has an internal sync generator which may be used for the as Master master reference. -
Page 52: Phasing Using F1-Blu/F2-Yel Test Signal
Phasing Using F1-BLU/F2-YEL Test Signal Phasing Using The MVPHD-24 generates a special test signal for the purpose of phasing the camera with the monitor (“F1-BLU/F2-YEL”). It is a field alternating signal F1-BLU/F2-YEL Test Signal that appears to the eye as a gray flashing image. The signal is actually blue in field one, and yellow in field two. -
Page 53: Wide Camera Shutter Angles (>> 180 Degrees)
Wide Camera Shutter Angles (>> 180 degrees) In order to film standard 24 Fps video, the camera shutter angle needs to be approximately 180 degrees. Often times however, larger shutter angles are desired or required by the director. Using the MVPHD-24, it is possible to increase the shutter angle and still avoid any artifacts in the picture. -
