I have a rather lengthy time lapse sequence with 14 different footage sequences and I need to create proxies for all of them so I can scrub my composition and adjust exposure etc. I've been creating them very well, accurately and visible. Sadly one section of footage seems to move about one pixel when I switch the proxy on and off.
However when I expand the footage in the timeline window none of the position numbers change. But there is a visible shift on the screen. I tried comparing Full and Half resolution in the Down Sample pull-down, the proxy is a half-resolution proxy. I can still see movement. It is minute, but visible. Why only this proxy? I re-imported the raw sequence footage, re-created the proxy, problem is still there.
It happened a couple of times earlier today and I was able to get rid of it by deleting the footage, corresponding comps and then re-importing, but not this time.
