Matchmover Notes

Camera Shoot Data

• When shooting record the focal length in mm & type of camera (vocal or clap board)
• might as well record all settings
• focal length (mm)
• F-stop
• Shutter speed
• ISO
• exposure
• type of camera
• Matchmover is expecting a full frame 35mm image sensor size.
• depending on camera type, you may have to adjust focal length in MM by it's corresponding crop factor

Camera --> General Tab

• Range = fixed
• init = focal length from shoot [x Crop Factor (1.62 for the 7D)]
• Flim back width = find on the camera's spec sheet (web-site)
• Film back width ratio MUST EQUAL image ratio
• R = w/h
• *image sensor size is the same term as film back

Canon 7D Image Format (APS-C) 22.3x14.9 ratio 1.4966442
1280x720 = 1.77777777                22.3/1.77    =   22.3x12.543
1920x1080 = 1.77777777              22.3/1.77    =   22.3x12.543
720x480 = 1.5                                22.3/1.50    =   22.3x14.86666
