Speeding up or slowing down an entire layer by the same factor throughout is known as time-stretching. When you time-stretch a layer, the audio and the original frames in the footage (and all keyframes that belong to the layer) are redistributed along the new duration. Use this command only when you want the layer and all layer keyframes to change to the new duration.
If you time-stretch a layer so that the resulting frame rate is very different from the original frame rate, the quality of motion within the layer may suffer. For best results when time-remapping a layer, use the Timewarp effect.

Time-stretch a layer from a specific time
In the Timeline or Composition panel, select the layer.
Choose Layer > Time > Time Stretch.
Type a new duration for the layer, or type a Stretch Factor.
To specify the point in time from which the layer will be time-stretched, click one of the Hold In Place options, and then click OK.
Layer In-point Holds the starting time of the layer at its current value and time-stretches the layer by moving its Out point.
Current Frame Holds the layer at the position of the current-time indicator (also the frame displayed in the Composition panel), and time-stretches the layer by moving the In and Out points.
Layer Out-point Holds the ending time of the layer at its current value and time-stretches the layer by moving its In point.
Time-stretch a layer to a specific time
In the Timeline panel, move the current-time indicator to the frame where you want the layer to begin or end.
Display the In and Out columns by choosing Columns > In and Columns > Out from the Timeline panel menu.
Do one of the following:
To stretch the In point to the current time, press Ctrl (Windows) or Command (Mac OS) as you click the In time for the layer in the In column.
In the Timeline or Composition panel, select the layer.
Choose Layer > Time > Time Stretch.
Type a new duration for the layer, or type a Stretch Factor.

To stretch the Out point to the current time, press Ctrl (Windows) or Command (Mac OS) as you click the Out time for the layer in the Out column.
Time-stretch a layer but not its keyframes
When you time-stretch a layer, the positions of its keyframes stretch with it by default. You can circumvent this behavior by cutting and pasting keyframes.

Make a note of the time at which the first keyframe appears. (Placing a composition marker is a good way to mark the time.)
In the Timeline panel, click the name of one or more layer properties containing the keyframes you want to keep at the same times.
Choose Edit > Cut.
Move or stretch the layer to its new In and Out points.
Move the current-time indicator to the time at which the first keyframe appeared before you cut the keyframes.
Choose Edit > Paste.
This seems to be the most common question with After Effects so here's a tutorial that will show you how to export/render in After Effects.

This seems to be the most common question with After Effects so here's a tutorial that will show you how to export/render in After Effects.
1. Generally when working in After Effects you'll constantly be setting the work area start/end points (B key / N key) so you can preview only the part of your composition that you're working on. Before you add your composition to the render queue you'll need to reset this (assuming you want to render the whole composition).
2. Place the playhead at the start of your composition. You can drag, but pressing the home key is the easier and more reliable method.
3. Now that the playhead is in the right location press B to set the work area start location. Again, you could drag the bar below the playhead, but using the shortcut keys is easier, more efficient, and more reliable.
4. Now drag the playhead to the end of the composition or press the end key.
5. Press the N key and set your work area end location. Then add the composition to the render queue.
6. The Render Queue tab will appear in the timeline area. I'll be leaving the name of my file and output location alone, but if you want to give your movie a filename to be saved as you would click on the "Comp1.mov" text and it would bring up the "Output Movie To" menu. The menu will also allow you to change the location of where your movie will be saved.
