Hi Kevin,
I apologize for the delay in responding back but I appreciate your help nonetheless. The clip was recorded on my Canon 5D Mk III in 1920x1080 24 fps IPB (so high compression). And I think the camera records in ProRes 422, correct? Does this offer any insight? I think I understand the point you were making with the legacy version QuickTime but I'm still unsure of how to be able to work around the issue I was having and reinstall CS6.
