I've got a project where there's 6 hours of video in Premiere Pro, and I'm amending some titles throughout it by cutting the section to be amended, sending it to After Effects and making the appropriate amends, by masking sections of the video to patch over old fonts used etc.
I'm about 3 hours through and all was well, until now. Now when I copy and paste a mask onto a new video clip and try and amend any keyframes on the mask, the keyframes are invisible. They're still there as the mask still animates and I can jump form invisible keyframe to invisible keyframe using the J & K keys. If I make a completely new mask and try and add keyframes, they're still invisible.
I've tried to remedy this by restarting all the software and machine. I've also boosted the size of my disk cache to double what it was previously (now 75gb - although I'm not sure what this does).
I'm running on the latest version of Adobe CC and my machine is a Retina Macbook 2.7ghz processor, 16gb ram, with an NVIDIA GeForce GT 650M 1024 MB graphics card.
