Hi there,
Thanks very much for your response; I had a look at the After Effects site, as you suggested, and it told me to :
1. In a Composition or Timeline panel, select the layer that you want to remap.
2. Choose Layer > Time > Enable Time Remapping.
This command adds two Time Remap keyframes by default, one at the beginning of the layer and one at the end.
3. Move the current-time indicator to the frame that you want to freeze, and set a Time Remap keyframe at the current time by clicking the keyframe navigator diamond for the Time Remap property.
4. Select the last two Time Remap keyframes (the second and third keyframes) and drag them to the right.
5. Press F2 to deselect the keyframes, and then click the second (middle) keyframe to select it.
6. Press Ctrl+C (Windows) or Command+C (Mac OS) to copy the keyframe.
7. Press Ctrl+V (Windows) or Command+V (Mac OS) to paste the keyframe at the current time. You should not have moved the current-time indicator since step 3.
8. (Optional) To extend the layer so that its duration is increased to accommodate the time added by the freeze-frame operation, press the K key twice to move the current-time indicator to the last Time Remap keyframe, and press Alt+] (Windows) or Option+] (Mac OS).
The portion of the layer between the first and second keyframes plays at an unaltered rate (the same as for the non-time-remapped layer), as does the portion of the layer between the third and fourth keyframes. The second and third keyframes are identical, so a single frozen frame plays during the time between those two keyframes.
The problem is, I can do steps 1, 2, and the first part of three, but then I come unstuck – I don’t know what the ‘keyframe navigator diamond for the Time Remap property’ is, and I don’t where the third and fourth keyframes are supposed to come from. Can you help me with this? Or do you perhaps know a good site that would have video tutorials? My difficulty is that if I don’t know the terminology, I can’t follow the instructions.
Sorry to be such a blockhead
