Hi,

I've noticed an occasional problem in 1.5. Not sure if it's the right forum here but the problem does only show up upon rendering and export, so here we go!

Sometimes there is a slight drop in luminance during transitions for just the period any video is overlaid (i.e a fade up or down).

It exhibits itself as the peak luminance parts of the picture dropping in brightness for the duration of any overlay. Even if (say) a clip is overlaid at 0% opacity the visable clip will show the problem. The darker parts of the picture don't suffer as much. But any bright colours go very slightly grey.

I first noticed it when editing in HD using the Cineform codec but it happens in SD as well, be it footage from my Sony Z1 in HD or SD or my PDX-10 in SD.

It seems to happen at random. One transition will be fine and the next will play up.

Searching on the web hasn't yielded much help. So I was wondering if you guys know anything?

It's almost as if some kind of luminence legaliser is kick in, but only for the duration of any transitions.

Any ideas? I feel like I've tried everything (this has been a problem for me for months).

Thanks.
