align & straighten

Align & Straighten is a plug-in available on iMovie that's specifically designed for post-processing clips that were filmed with the camera at an angle. Its intended use is to adjust the clip slightly so that vertical lines are vertical again. During configuration, Align & Straighten provides additional cues to help you align the clip. It doesn't just rotate the clip, but allows you to zoom and crop it as well as move it slightly along the horizontal and vertical axis.

The plug-in is perfect for straightening out footage that requires slight realignment after being filmed with a camera that's set up at an angle. Here are key features of Align & Straighten:

- Grey crosshair grid: This visual aid helps you align the clip with horizontal or vertical lines. They will not show up in the processed clip.
- Background color: When you crop and/or rotate the clip, everything outside the 'area of effect' will be set to this color.
- Rotation: This slider controls the amount of rotation required to make vertical or horizontal lines appear correct. Use the hairline grid as a reference.
- Zoom: When you rotate the clip, the result will no longer fit into the frame. For some parts that fall off, other parts around the corner will reveal the background. Use this slider to slightly zoom in, pushing out those parts that reveal the background.
- Horizontal shift / vertical shift: These sliders allow you to move the clip up/down or left/right, allowing you to re-align the center.

Overall, Align & Straighten is an exceptional plug-in that helps users to align their clips with ease. Its features and user-friendly interface make it a must-have editing tool for those in the world of video production.
