aperture width in c4d

[beachouse]

I'm trying to match up some footage from a camcorder - it's 16:9 PAL D1 (720/576) from a Sony DCR-SR90

 

I've matched it pretty well eyeballing it for most of the shots. However I thought I'd try and get the specs off the camera as I thought that would help.

 

The specs say:

 

5.9 mm (1/3 type) CCD

 

Does cinema use the diagonal size for aperture width? I couldn't find much info about the individual camera but for 1/3 inch CCD here: http://www.dpreview.com/news/0210/02100402sensorsizes.asp I found this

 

Aspect Ratio 4:3 Dia. (mm) 8.467

Diagonal 6.000 Width 4.800

 

 

 

Is this info any use to me? when I use the Dia, Diagonal or Width for the aperture width with anything in the focal length range of the camera I get such a narrow field of view I can't seem to match it up at all.

If you still have access to the camera you could do a test to figure out it's field of view at various zoom levels. Put the camera on a table a known distance away from the wall and at a right angle, and put a ruler against the wall starting from the center of the view and going on one direction. Record sections at various zoom levels and look at the footage to determine the width of the view. It is a good idea to capture the footage, then digitize it and look at the digitized footage. The LCD may have false edge cropping to mimic action safe and title safe. When measuring the distance to the camera measure from the wall to the center of the lens assembly.

 

here is a little trig,

 

Angle of view = 2 * (tan (distance along the wall / distance from wall))

 

Hope this helps.
