Adobe After Effects CS5 - Having Timeline 'Helpers'

Once you have selected the content of your video After Effects, it is easy to modify the different layers, their time time, add effects, and of course, their relationships to each other edition. This "fine tuning" stage may be the most important and for many of us may be longer. Fortunately, After Effects includes several useful tools here, and a tool of choice, is simply the "slip editing'. Slip editing we can change the start and end in the different layers when editing their presence in your video. After Effects timeline also provides many "assistants" to help with the editing process.

To introduce and experiment with editing or sliding, to select three or four videos you want to merge into a single composition. Place them in different time intervals and using the time setting changes each time is used less than the full video. By placing the mouse on the start or end of a layer, is the "double arrow" indicating that you can slide the time editing the layer of the part of the video is shown first (or last).

If you do not see the double arrows at the end of the video layer, but can extend beyond the time window of its composition. Look at the small bar at the bottom right of the timeline. He has two small icons pyramid on each side. This slider and pyramids allow you to expand (and outside) in parts of your timeline.

This can be useful when you are putting in place, perhaps only a fraction of a second, but also hides the details of the timeline. All the tools, I think we all have experienced some frustration in After Effects, when we follow the directions, but just does not seem right. So ... The two cases do not see the arrow of time to change layers, make sure you are at the beginning or end, be sure to time slider is not always to the left, so exposed to all the timelines, and finally, the layer is viewing may actually be longer than the same composition.

If you've tried everything and still can not see two arrows at the end of your floor, push it inward. Use the mouse to move the entire layer in the Timeline to the end, then when you move the mouse at the end of a piano bar, you'll see two arrows, as well as reducing the end of this video.
