For one of the episodes of the show I'm working on at the moment we have a 'tv look' effects, basically a bit of Bad TV, some Color Correction, Scanlines, a show bug... We've been careful to make sure the Luma Levels stay legal when we're setting them up. But when we render we get a different result, pushing our luma outside of the legal range.
What the hell is happening?
Here's two screenshots that demonstrate the problem - they are frames next to one another, the unrendered one (the preview we can work with when setting up the effect) is fine, but the rendered on (what's going to end up on tape) is no good.

I need to resolve this ASAP as this needs to be on tape and at the network soon. I did look at using the video safe filter, but it's make a pretty horrible hard clip that is very visible and unappealing.
