RAW camera motion import/export format

[robcat2075]

A:M has a format for importing/exporting camera data. For what it's worth, it seems to work like this...

 

It is a text file that appears like this

A Spreadsheet program like OpenOffice can interpret the spaces as separators and create something formatted like this

(Click to enlarge)

First row: number of frames, number of columns

 

The rows after that seem to contain the data columns like this:

 

A- frame number

B- X Translation in cm

C- Y Translation

D- Z Translation

E-I- unknown

J- X Aim

K- Y Aim

L- Z Aim

M- Focal distance in cm

N- Z rotation degrees (rotation on barrel axis)

O- Focal length

P-Q- unknown

 

The "Aim" data seems not to be actual angles but XYZ coordinates in space measured from the camera axis that the camera is pointed at. I imagine with some trigonometry that result could be converted by the spreadsheet into any angle format that some other camera system might need. Likewise, a spreadsheet could reformat this data into any order needed by another program.

 

If you have some other app that can understand a text format for camera data, this A:M .RAW format looks like a starting point for that.

Many years back I wrote a program that took the data for the camera and converted it for use in electric image. I was doing character work in am and rendering over matching backgrounds in ei.
