When creating images for video, you can load a set of video actions (included with Photoshop) that automate certain tasks—such as scaling
images to fit video pixel dimensions and setting the pixel aspect ratio.
Load video actions
For video images, actions automate tasks such as constraining the luminance range and saturation levels to comply with broadcast standards,
resizing and converting to nonsquare pixels for use in DVD slide shows (NTSC and PAL, standard and widescreen aspect ratios), creating an
alpha channel from all currently visible layers, adjusting image areas (especially thin lines) that are likely to cause interlace flicker, and generating
a title-safe overlay.
1. Choose Window > Actions to display the Actions panel.
2. Click the triangle in the upper right corner of the panel, and choose Video Actions from the menu.
