What causes blending? (picture included)

[mimage]

When I render my video in Vegas.. I get this happening.



I have deinterlaced my footage, and there isn't any blending like this even if I go frame by frame in the AVSEdit preview to see if any of this is going on just incase I may have deinterlaced it incorrectly and I don't see any of it.

Even in my timeline in Vegas, if I go frame by frame I get no blending, but then when I render it I get it, even at times when the input and output is the same framerate. So what causes it and how can I prevent it from happening? Thanks.

I've worked on this for a while and already had a lot of help in another thread (not a doom9 thread), but this problem is still continuing and would like some help from here.

Edit: OK it has come to my attention that akira is progressive and that I'm suppose to use force film right? I was sure I did that but as I'm testing right now, I don't see any blending. I think I did honor pulldown frames and that could of been causing the problem. If the problem persists, I'll report back.

Edit again: I've tried force film, made it at 24fps in my avs script and made it 24fps in my Vegas project and 24fps on my export yet still getting blending.

Here's another screenshot of what I get when I render.

Please help.

Update: Look at the other thread. Looks like me slowing down the footage a tiny bit caused the blending.
