Chad Mahadevan Posted December 2, 2018 Share Posted December 2, 2018 Hey All, I just finished shooting a series of yoga workouts on a black background with the Alexa Mini (2 Camera Shoot). About a month after shooting, the editor noticed a number of white specks throughout the footage (both A and B camera). The white specks would randomly appear in a one frame and disappear in the next (no consistency to area of frame). After speaking with Arri, they believe that this is an environmental issue caused by cosmic radiation. We've currently found about 15 specks within 3 episodes of shooting (which were shot on 3 different days). See below for a couple of samples with the specks. Let me know if you've seen anything like this before. We're going to be shooting the next round in a week and are trying to prevent this issue. Best, Chad Mahadevan Link to comment Share on other sites More sharing options...
Bruce Greene Posted December 2, 2018 Share Posted December 2, 2018 I have seen similar, but it was on a single, defective camera body... Which we replaced. I don't think one can avoid cosmic rays :( Link to comment Share on other sites More sharing options...
Chad Mahadevan Posted December 6, 2018 Author Share Posted December 6, 2018 (Update) I have recently tested (2) different Alexa Minis in a separate location and have had the same issues. Link to comment Share on other sites More sharing options...
