Hi everyone.
The Panasonic GH4 specs are as follows when set to 1920x1080P. In this mode there is NO cropping of the native image sensor.
Aspect: 4:3
Sensor: 17.3mm x 13.0mm
Video Size: 35mm
When I put these measurements into FF3D and set up prime lenses for 12mm, 14mm, and 25mm I find that the image is not consistent in FF3D with the real world.
I took physical measurements of a room and its windows. Top to bottom, side to side, depth, window measurements (from ceiling, from floor). I measured the placement of the camera distance and lense height for a test image. I then built a set inside FF3D that fit the exact measurements of my test room.
I find that FF3D seems to add a solid 2 feet or more in the top and bottom of the screen. The left and right of the image seems to be only off by about 2-3 inches of the real life camera image. Any ideas as to why this is happening and how to really lock in FF3D to be exact?
