When checked, makes the background transparent (useful if the clip with the effect is superimposed). To access this option
from the Applied Effects panel, click the Setup button to the right of the effect name.
Clip (Windows only)
The Clip effect trims rows of pixels off the edges of a clip and replaces the trimmed areas with a specified background color. If you want Adobe
Premiere Elements to automatically resize the trimmed clip to its original dimensions, use the Crop effect instead of the Clip effect
Crops each edge of the clip separately.
Specifies the color that replaces the trimmed areas. The default color is black.
Sets the units specified by the sliders, either in pixels or the percentage of the frames. Click the Setup button at the right of the effect name
to set units.
Crop
The Crop effect trims rows of pixels from the edges of a clip and, if you select the Zoom option, automatically resizes the trimmed clip to its
original dimensions. Use the slider controls to crop each edge of the clip separately. You can crop by pixels or clip percentage.
Edge Feather
The Edge Feather effect adds a darkened, soft-focused bevel to the edges of a clip. To adjust the width of the feather, drag the Amount slider left
or right.
Horizontal Flip
The Horizontal Flip effect reverses each frame in a clip from left to right; however, the clip still plays in a forward direction.
Horizontal Hold (Windows only)
The Horizontal Hold effect skews the frames to the left or to the right; the effect is similar to the horizontal hold setting on a TV. Drag the slider to
control the clip’s slant.
Roll
The Roll effect rolls a clip to the left or to the right, or up or down, as if the clip were on a cylinder.
Vertical Flip
The Vertical Flip effect flips a clip upside down. You cannot apply keyframes to this effect.
