Combining three- and four-point edits
In the previous task you performed various three-point edits in order to embellish the conflict between the insect and the snake. However, the insect's escape from the snake is a little sudden, so you will add a portion of another snake clip (Snake_Rear.avi), but using a four-point edit in order to control the new clip's duration on the Timeline.
Four-point edits are used to speed up or slow down a clip so that it can fit into a user-defined space on the Timeline. In this case you will use it to slow the content of a clip down by 50 percent, but keep the continuity of the action constant.
After the insect escapes it is also attacked by a frog; however, this is so quick the viewer will never have a chance to see it. To correct this you will combine three- and four-point edits to slow down part of this new clip (BB_Flyby.avi) to make the frog's attack a more prominent feature of the scene.
Engage Thrusters
Use the four-point edit technique to add clips to your sequence, changing the speed at the same time. Perform the following steps to do so:
- In the Source Monitor select the Snake_Rear.avi clip.
- You want to insert part of this clip into the Timeline, but at 50 percent of its actual playback speed in order for the clip to be visible for twice as long. To do this, first find and define the In point (point 1) and the Out point (point 2) for the snake clip using the skills learned earlier in this project. The suggested points are as follows:
- Set an In point at 02;00
- Set an Out point at 03;00
- Press Shift + 3 to make the Timeline active, then press the up or down arrow to send the Timeline indicator to the start of the last BB_Rear.avi clip on the Timeline (hint – if you have followed the previous instructions, this should be around 09;14 on the Timeline counter).
- Define point 3 of this four-point edit by pressing I on the keyboard to set an In point at this location on the Timeline.
- Move the Timeline indicator to 11;19 using any of the methods you have learned so far. Press O on the keyboard to set an Out point on the Timeline, and create point 4 of your four-point edit.
- Press Shift + 2 to activate the Source Monitor and press the ',' (comma) key to insert Snake_Rear.avi onto the Timeline between the two points defined in steps 4 and 5.
- Because you have defined (in the Source Monitor) a clip that is 1 second in duration and then you defined a gap on the Timeline that is just over 2 seconds in duration, the Fit Clip dialog window will appear. Select Change Clip Speed (Fit to Fill) and press Enter or click on OK. The clip will now appear on the Timeline at less than 50 percent of its true speed.
Note
Working out speed increases is simple enough. Here you defined the In and Out points to create a clip of 1 second in duration. On the Timeline you defined the In and Out points of 2 seconds in duration. This creates on the Timeline a space that is twice the size of the clip's set duration, meaning Premiere Pro needs to slow the clip down to slightly less than 50 percent in order for it to obey the rules of a four-point edit.
- Now you need to address the frog problem! On playback the frog attacks the insect with such speed that it cannot be clearly seen. To remedy this you will add another camera view, but this time adding half the clip as a four-point edit, then the remaining half as a three-point edit. This will create a sequence that shows a seamless slowdown and return to normal speed. To begin, select the BB_Flyby.avi clip in the Source Monitor.
- Define a four-point edit for this clip using any of the methods covered so far. Use the following suggested parameters:
- Set an In point at 03;15.
- Set an Out point at 05;15.
- Press Shift + 3.
- Set Timeline In point at 13;05.
- Set Timeline Out point at 17;05.
- Press Shift + 2.
- Send the clip using Overwrite (.).
- Select Change Clip Speed (Fit to Fill).
- Now you need to insert the second half of the clip as a three-point edit. Press Shift + 2 to return to the Source Monitor and confirm that the BB_Flyby.avi clip is still selected.
- Define a new set of In and Out points using the following suggested parmeters:
- Set an In point at 05;16.
- Set an Out point at 08;06.
- Press Shift + 3.
- Set Timeline In point at 17;06.
- Press Shift + 2.
- Send the clip using Insert (,).
- At the end of this task, the middle section of your Timeline should look something like the next screenshot. Use Undo if it does not. Save your project when everything is correct and then move on to the next section.
Note
When you add a four-point edit to your Timeline, a small red line appears above those sections of the Timeline that contain time-stretched clips. This means Premiere Pro CS6 must render these sections of the Timeline before export can be completed. It also means you might see some dropped frames when playing that section of the Timeline back. Whenever you need to render these red areas of the Timeline, simply press Shift + 3 to set the Timeline as active, then press Enter on the keyboard.
Objective Complete - Mini Debriefing
In this section you have discovered how to create a four-point edit from the keyboard and then you went one step further by combining a four-point edit with a three-point edit to show the clip slowing down, then resuming at normal speed. Both types of edits are invaluable to a video editor and it would be in your interest to learn these skills and use them with the keyboard in order to obtain a frame-accurate three- or four-point edit.
Classified Intel
A decrease in speed caused by the four-point edit is often used in video editing to force clips to last a fraction of a second longer, but to fit in with the context of the scene. Clips that are slowed between 75 percent and 99 percent will usually be indistinguishable from 100 percent playback speed. The classic example is perhaps a documentary where you as the editor are supplied with a commentary track that lasts a few seconds longer than the actual video clip. Getting the voiceover re-recorded could be costly; however, just slowing down a clip by a few percent can mask the problem and allow the voice to match the duration of the clip. Only you will know!
