Here's the situation.
All stock bought from Kodak directly.
Shot a music video with an Arri SR2 with new stock from Kodak - No problems
Shot 2 additional mags of short ends on an Aaton XTR - Stock about 2 years old - Refrigerated
One short end - 50 ft - No problem other than a slightly higher amount of grain than the Arri Rolls
The other has an issue - the grain pulsates - it's constant in its pulsing or and the grain is substantially more blue in the shadows than the previous roll.
By pulsating I mean it comes and goes at consistent fast intervals - its there - it fades out - it's there again
Can't post a clip as its for a major label and the material is unreleased.
Has anyone seen this before? Im just trying to avoid it in the future. Im assuming its the age of the stock - and possible mishandling but could it also be camera related?
Thanks
