Overview: Negative films (both 8mm and 16mm) require white balancing otherwise the finished film can be off in colour. I also found that if the white balance is off not only the colour can be impacted but so can the clarity of the image. I had one film that I incorrectly white balanced and the film had a green milky look about it. The milky look cleared up once the film was correctly white balanced.

White Balance - How:

1) Set VelocityHD to process NEGATIVE. 2) Load the film into the scanner and cue it up to a "white" section at the start of the film. Usually the best section is a clear piece of film at the beginning. 3) Push the menu button on the camera. 4) Toggle to the white balance and push the toggle in. 5) Run an 10 or 20 second test. 6) Process the test clip and view it. 7) If okay, proceed to the next step, otherwise repeat steps 2 to 6 on a different clip. 8) Re-cue the film to the start and scan it. 9) At the end, don't forget to RESET to WHITE BALANCE ..... set to white balance using no film in the gate.

Note

Setting the white balance on the capture camera WILL stay set even if the camera is turned off. What will NOT stay set is the exposure setting. If the camera is turned off the exposure setting will have to be re-calibrated (set it using the same method as before)
