I am having an error with some of my R3D files, where they have smaller framing in play back. Not all of them do it. Sporadic clips on the timeline will show smaller int the project monitor than the rest. They play perfectly fine in the source monitor. I have the project monitor set to Fit, so I don't understand why this is happening. I haven't been able to find a connection between the clips that have that problem yet, but if I do I will update this post.
When you find one in the timeline (Program Monitor)..."Reveal in Project" then check the properties of the clip against the others.
You maybe playing some kind of preview file and obviously that wont match the Sequence settings.
That wont show as wrong scale in the Source Monitor
I will definitely look into this, thank you.
