Proofing FbF data using ARC

Good practise would be to run some test footage through ARRIRAW Converter (ARC) and check

the Fame by Frame data (LDS) are properly written into the ARRIRAW files.

You can download ARC from the ARRI Website:

https://www.arri.com/en/learn-help/learn-help-camera-system/tools/arriraw-converter

● Download the test clip on a computer,

● Run ARC and, select the test clip using the browser tab,

● Once the clip is loaded select 'View' tab,

● Click on 'LDS', a popup tab will appear,

● The three lines, representing focus (blue), iris (yellow), focal length (green), display the

trend of the axis through the shoot.

If these lines are missing, the encoding was not successful.

Shooting a Test

When shooting test footage, allow approximately one hour per camera type being used on the

production. A test will involve recording the metadata with a camera and recording a separate

feed from the camera with an overlay to verify the data is correct at the final stage of the test.

We recommend using a zoom lens (if any are being used during the shoot) in order to check all

three axes.

To do a test:

● Encode a lens and test it (see "Programming a New Lens Table"),

● Shoot test footage in camera and record separate overlay feed at the same time,

● Extract the Frame by Frame data using Arri Metadata Extract (see Appendix #),
