I am using Blender 2.76b.
None of these suggestions have worked for me:
- Doing a hard cut. I am doing this multiple times to leave a gap, which I want to fill in with the freeze frame
- RMB to grab the right arrow, which I want to extend
- Press g and drag it, which will create a freeze frame on the last frame if extended beyond the original size.
I've tried this selection and tried both g and e and neither work. It seems to want to let me either move it or make the clip smaller but not extend beyond its original size.
