I've been doing some further investigating.

It seems like this is some kind of bug in Premiere. If the luma levels are above 100% (don't ask me how) it will clip back the luma during the transition. It's very obvious when you look at the luma graph that this is happening.

If you reduce the luma levels to 100% (e.g by using the video limiter), it doesn't happen.

How I'm ending up with luma levels above 100% to begin with I don't know. But since Premiere appears happy with these levels the rest of the time combined with the fact I am using industry standard kit (the Sony Z1) I'm not sure.

I do usually run a limiter over any finished production, but it's annoying that Premiere has this bug. Unless it's me who is doing something wrong. But I can't see how. It's hard to avoid peak white in an image from time to time (espcially if working with a high contrast scene).
