The extend edit function is available in most mature non-linear editing programs and Adobe Premiere Pro CS5 and CS5.5 is no exception. The way an extend edit works is to first place the the current time indicator (CTI) or playhead either before or after an existing edit, engage a keyboard command and then the edit point does a roll trim to the CTI or playhead. To clarify, an extend edit is merely a roll trim that is performed with the playhead and a keyboard shortcut. It’s really a time saving edit function that all should be familiar with.
Achieving an extend edit in Adobe Premiere Pro is very simple, however, you’ll have to customize the keyboard first in order to have access to the function in Premiere Pro CS5 (in Premiere Pro CS5.5, they are already set up for you, so the following steps are unnecessary).
- Go to Edit > Keyboard Customization
- Ensure “Application” is chosen in the drop down menu.
- In the Keyboard Customization dialog, scroll down until you see Roll Next Edit to CTI and Roll Previous Edit to CTI.
- Select “Roll Previous Edit to CTI” by clicking on the name.
- Click once in the Shortcut field next to the command.
- Type “E” for extend.
- Repeat the process for Roll Next Edit to CTI, except use Shift + E for that command
- The Set command for the keyboard will now say [Custom]. You now have a custom set of shortcuts to customize as you see fit, name it by clicking the Save As button and then entering in a name for it.
- Click the OK button and the Keyboard Customization window closes.
Now that the keyboard has been properly set up, you’re all ready to go. Follow these steps to complete an extend edit:
- In the timeline, target the track(s) that you wish to do an extend edit.
- Move the CTI/playhead to a new position either before or after the existing edit point.
- Press E to extend an edit forward to the playhead or Press Shift + E to extend an edit backward to the playhead.
- Your extend edit is now complete.
This technique is the fastest way in the world to do a roll trim. It works great with audio tracks, as well.
Since we all have a need for a Roll trim in everyday editing practice, I encourage you to map your keyboard right now so that you’ll to be ready to use an extend edit in your next editing session. Doing an extend edit is far faster than reaching for the Rolling Edit tool and then clicking and dragging to make the trim.
Tip: If you target more than one track, the extend edit will function on all of those selected tracks. To see this in action, check out the following example:
Let’s say that I want to do a roll trim to line up the edit points on V2 and Title on V3 with the edit point of the clip on V1. First, I snap the CTI to the existing edit for the clip on V1. Then I select the V2 and V3 video tracks as shown:
Next, type Shift+E to Extend (or Roll) the edit point to where the CTI is positioned.
Note that all three edit points are now aligned quickly and perfectly. If the clip’s edit points are not aligned, one thing may have gone wrong: insufficient handle. An extend edit behaves just like a trim with the Rolling Edit tool and is also subject to the limits of media beyond the chosen in and out points, so be aware of that.
So, there you have it! A great technique that is used by the pros every day. Because of this function, I rarely use the Rolling Edit tool to make roll edits. It’s just too slow if you know about the extend edit function! I find that the extend edit technique saves me a ton of time in trimming and manipulating edit points of clips, graphics, titles and audio and I hope it will do the same for you.
