I'm working on a 25i project. All footage is interlaced, from DV source.
I have used the colour correction tool to adjust each shot, but found that some shots are being deinterlaced by the colour correction effect. I have checked carefully, and no other effects are present.
If I open the effect editor on a clip that this has happened to, when I step through field-by-field I can see that odd fields are identical to even fields.
This doesn't happen with all clips, only a few. It doesn't seem to matter what I do within the colour correction tool, either!
What do the clips, which are affected, have in common?
ACSR
Media Composer, Symphony, DS, Unity
That's what I've been puzzling over. They all originated from the same camera (but so did about 50% of my timeline. They may have originated from the same tape (but so did many other clips on the timeline). The picture content varies widely. Two of the clips were slightly overexposed, but another was rather underexposed.
I really can't see, or think of, anything relevant that they have in common.
interesting I never have seen a cc do a deinterlace. I don't even think it is possible. Can you attach some images showing the problem?

Funnily enough, I think I have seen it happen before. I have sometimes seen deinterlaced material suddenly appear in some of my students' work after they have colour corrected. When I ask why they deinterlaced some clips they give me a blank stare. This is the first time I have seen it happen in one of my own projects.
I've actually put that project to bed now (I used a manually-adjusted colour effect instead of the colour correction tool for the problem clips). But I will try to post some images in a couple of days.
