I'm trying to keyframe Time Remapping in Premiere Pro CC 7.0.1, following the Adobe TV Tutorial (which uses a version of CS6/CC previous to the July 2013 update) and am unable to add keyframes directly to the timeline or adjust speed keyframes in the Effects tab. Am I missing a newer technique? I'm on a Mac Pro, OSX 10.8.3. with Nvidia Quadro 4000. Thanks
Click on the FX in the clip and select Time Remapping - Speed
Hold down ctrl (cmd) to add keyframe on the clips white line in the timeline.
I find it easier to adjust the keyframes on the timeline.
Maybe the help is a bit clearer on this:
Ctrl (cmd) + alt (Option) to freeze
Ctrl (cmd) + drag to reverse
