Preview

The tabs above the preview set the view. Original shows the clip as it is. Result shows the clip with your settings. Split divides the picture at a line that you drag. Side shows the two next to each other.

Hold the backtick key (`) to see the original, and release it to go back to your view.

Scroll over the preview to zoom. Drag to move the picture. The zoom button shows Fit or the zoom level. Press it to fit the picture, or double-click the picture to return to the default zoom.

Default preview zoom in Settings sets that zoom. When it is Fit, a double-click fits the picture too.

Playback resolution sets the size of the preview: Auto, Full, 1/2 or 1/4. A lower size plays more smoothly. Turn off Preview in the right-click menu of the picture to hide the preview.

Preview memory in Settings sets how much memory the preview can use.

Save frame, or Ctrl Shift E, saves the picture in the preview as a PNG file next to the source clip. A note appears with Copy file and Show in folder.

Press Transform to show the transform box of the selected clip. The box moves, scales and crops the clip on the canvas.

Double-click the box to reset it.

Drag the box to move the clip. The arrow keys move it by 1 pixel, and by 10 with Shift.

Drag a corner to scale the clip around its center. The plus and minus keys scale it by 5 percent.

Drag the handle on an edge to crop that side.

Shift drag the handle on an edge to stretch the clip on that axis instead of cropping it.
