I get these kind of anomalies on footage more than I'd like to. Not necessarily from that particular camera. Usually it's an operator action that triggers it, either running auto iris or bumping or changing some parameter. Now I have a patent pending solution to these issues that works a majority of the time. It requires the Artist Color Panel. First set up the panel in a vary accessible area of the edit console. You need to be able to move the panel freely to avoid repetitive motion injuries. Next spend an hour or two setting up the ethernet link on port 2 of your MacPro. Set the panel into HSL mode and remove the 3 track balls from the console and put them in a safe location, the value of this will be explained shortly. Now find the point where the iris shift begins and add an edit then determine the duration of the iris shift, remember in CC mode things move in fields not frames so divide by 2 for the number of frames. Now park on the the frame before the add edit and set one of the side monitors to reference that picture. Now park on the final frame of the iris shift and compare it to the reference frame to get an idea of how to adjust the second section of the shot. Make sure to be in src segment mode for this adjustment. Now toggling between the two will help in the correction, too bad we no longer have split to reference ;-(. Now making sure you have ample length on the cables for all the connections to the Artist Color panel, e.g. ethernet and power, it's time for the critical patented part of my approach. Invite the cameraman that shot the footage into the bay and show him the toggle between the reference and the shot needing correction so he/she sees it. Suggest they lean close to the program monitor to see the error more clearly. Now the fun part. While they are not looking pick up the Artist Color Panel and whack them over the head with it while shouting, "Bad Camera Person." Now you can see the need for removing the track balls as they might leave a traceable mark. Hopefully you will never see this error again from this operator. Rinse and repeat as needed. Remember this is patten pending. Sadly this is the most useful function I've found for the Artist Color Panel when it comes to Avid, hoping that will improve in the future.
Can you tell I have a long render going?
