Compressor
Identifies the codec (compressor/decompressor) that Adobe Premiere Elements applies when
previewing movies. The codec is defined by the project preset; you cannot change it because it must conform to the
DV standard.
Note: If you use a clip in your video program without applying effects or changing frame or time characteristics, Adobe
Premiere Elements uses the clip’s original codec for playback. If you make changes that require recalculation of each
frame, Adobe Premiere Elements applies the codec identified here.
Optimize Stills
Select this option to use still images efficiently in projects. For example, if a still image has a duration
of 2 seconds in a project set to 30 fps, Adobe Premiere Elements creates one 2-second frame instead of 60 frames at
1/30 second each. Deselect this option if projects exhibit playback problems when displaying still images.
Undoing changes
Undo changes incrementally
If you change your mind about an edit or effect, Adobe Premiere Elements provides several ways to undo your work.
You can undo only those actions that alter video content; for example, you can undo an edit, but you cannot undo
scrolling a panel.
•
To undo or redo the most recent change, choose Edit > Undo. (You can sequentially undo a series of recent
changes.)
•
To undo a change, and all successive changes that occurred since you last opened a project, delete it from the
History panel.
•
To stop a change that Adobe Premiere Elements is processing (for example, when you see a progress bar), press Esc.
•
To undo all changes made since you last saved the project, choose File
> Revert.
To undo changes made before you last saved a project, try opening a previous version in the Premiere Auto-Save
folder. Then choose File > Save As to store the project outside of the Premiere Auto-Save folder. The number of
changes you can undo depends on the Auto Save preference settings.
Undo any previous change
The History panel records the changes you make to a project. For example, each time you add a clip, insert a marker,
or apply an effect, the History panel adds that action to the bottom of its list. The tool or command you used appears
in the panel along with an identifying icon. You can use the panel to quickly undo several changes. When you select a
change in the panel, the project returns to the state of the project at the time of that change. The more recent changes
turn gray and disappear when you make your next change.
The History panel records changes only for the current session. Closing a project or choosing the Revert command
clears the History panel. While the panel lists most changes, it does not list individual changes within some panels, nor
does it list program-wide changes, such as Preferences settings.
•
To display the History panel, choose Window
> History.
•
To select a change in the History panel, click it.
•
To delete a selected change, click the Delete icon
, and then click
OK.
•
To move around in the History panel, drag the slider or the scroll bar in the panel. Or, choose Step Forward or Step
Backward from the History panel menu.
•
To clear all changes from the History panel, choose Clear History from the History panel menu, and then click
OK.
