Hi there - Hoping someone out there can help as I've been Googling all day without any luck and spent 2 hours on screen share with Adobe today without an answer.
Anyone had this problem? I can add keyframes on video (for example, opacity) or for motion (time ramping), but can't actually move those keyframes once they've been added. I'm unable to click and drag to change the speed on time ramping or the opacity. Same with audio. Can add keyframes, but can't do anything with them once they're in the timeline.
I also can no longer drag the mouse over the position X and Y in effects panel to reposition the video. If I type in a manual value, the video will move. But can no longer drag right and left to change those values.
Until today, I never had any problems editing with keyframes in Premiere Pro CC 12.1. I'm operating on 10.13.5, MacOS High Sierra. Keyframes are still working for me in AE on the same comp.
Can anyone offer any advice? I've tried clearing my preferences, re-installing the program, updating to the latest software (and also re-installing a slightly older version) etc....
I had this problem and I just resolved it. For now anyway. I couldn't click and drag to adjust any settings in the control effects panel, and I couldn't raise or lower audio levels with keyframes ona clip. I run a Mac mini with an external graphics card and for me it was a case of power cycling the graphics card. I rolled back PP versions, reset prefferences, all that stuff. I removed the graphics card and the problem went away. So I updated back to the latest version of PP, power cycled the graphics card and it's all back on track. Hopefully it sticks.
