In a hurry? Use the Project Preview Window quick guide instead.
The Project Preview Window is where a PowerDirector edit comes together, and it does a good deal more than play and pause. The controls around it set the project's aspect ratio, step the video a frame at a time, change how much work the preview does before it plays, and take a still of whatever is on screen at that moment.
A Tour of the Project Preview Window
Prefer to watch? Here's the whole tour in a four minute video, or follow the written sections below.
Two Preview Windows, Two Jobs
PowerDirector actually gives you two preview windows, and it helps to know which one you're looking at. The Media Library Preview Window plays a single clip you've clicked in the library. The Project Preview Window plays your timeline, which is everything stacked together the way it will export.
Play, Pause, and Step
The playback buttons sit under the bottom left corner of the preview. Click play or pause, or just tap the spacebar, which is the one most editors end up using. Stop sends the playhead back to the very start of the timeline.
For finer work, the two step buttons next to them nudge the playhead one frame at a time. That is how you land a cut on an exact frame rather than near it.
Set the Project Aspect Ratio
Worth doing before you get deep into an edit, because it decides the shape of what you export. Click the ratio button at the bottom right of the preview and pick from 16:9, 9:16, 1:1, 4:3, 4:5, 21:9, or 360. Landscape video is almost always 16:9, and 9:16 is the one you want for phone-first video.
Switch to 9:16 and the preview reshapes straight away, so you can see how your framing holds up before you commit to it.
Fill the Screen
Small details are hard to judge in a small window. Click Full Screen View, or press F, to blow the preview up to the whole display. Press F again, or click the X, to come back to editing.
Switch the Layout
The Layout button gives the preview three different shapes, and which one suits you depends mostly on what you're cutting:
| Mode | Best for |
|---|---|
| Landscape | The default. Standard 16:9 edits, with the preview across the top |
| Portrait | Vertical 9:16 edits. The window stretches from the top of the screen to the bottom |
| Floating | Detaching the preview so you can put it anywhere, including on a second monitor |
Floated the window and want it back? Click Dock Preview Window at its top right and it snaps home.
Zoom the Preview
Click the magnifying glass to scale the preview image up or down, which is handy when you're lining up a title or checking a mask edge. Hovering over the preview and scrolling with Ctrl held down does the same thing without leaving the mouse.
Choose a Preview Quality
Under the menu icon, Preview Quality sets the resolution PowerDirector renders the preview at. Higher settings look sharper but ask more of your computer, so HD suits most machines. If yours has room to spare, push it up for a clearer picture while you work.
Keep an Eye on the Volume Meter
In the same menu, Preview Volume Meter puts a live level meter beside the preview so you can see how loud your audio actually is instead of guessing.
Stay out of the red. Levels that sit in the red band for any length of time clip the audio, and that distortion is baked into your export. Pull the volume down until the meter peaks below it.
Render Preview When Playback Stutters
If the preview keeps hitching on a busy stretch of timeline, that's your computer struggling to build every frame on the fly. Click Render Preview and PowerDirector renders that section once into a temporary file, so playback runs smoothly from then on.
Take a Snapshot
Spotted a frame you want as a still, maybe for a thumbnail? Park the playhead on it and click the camera icon, then choose where to save. The image also lands in My Media, so you can drag it straight back onto the timeline without hunting for the file.
Haven't got PowerDirector yet? Play, step a single frame, set the aspect ratio, grab a still. These are the controls you reach for in your first hour of editing.

The Media Library Preview Window plays one clip you've selected in the library, on its own. The Project Preview Window plays your timeline, with every track, title, and effect combined the way they will export.
No. Preview resolution only affects what you see while editing. What gets exported is decided by your export settings, so a lower preview quality is a safe way to keep editing smooth on a slower machine.
You choose the folder when you save one. The same image is also added to My Media, so it's ready to drop onto the timeline without importing it again.
