Something weird just happened...

I was working on 3D muxed footage from beam splitter rig and all the images from left camera were properly flipped using firstlight before.

But today, when I choose a clip from media bin and as soon as I click on left(or right) 3D corrections panel, the image flips back to normal and both of horizontal/vertical flip doesn't work anymore!!

any idea? argh!!

No idea, the codec is not showing this failure on the PC (same code as the Mac.) Did you do an upgrade, change a database, etc? Please contact support.
