Video Position Presets:
One of the great benefits of using Zoom Player is its ability to position the video anywhere on the screen while providing a color background (usually black to prevent brightness bleeds). This allows you to cut down on the usual overscan you get when outputting video to a CRT TV set (if you're not aware of overscan is, read this article).
To position the video area, use the Shift+Arrow keys to change the top and left positions of the video. Using the ALT+Arrow keys you can resize the width and height of the video area.
Using the +/- keys (optionally with Ctrl and Alt held to control a specific Axis) you can Zoom the video area IN/OUT.
You can further automate this process by using the Resize Navigator (Shift+"S").
After your video has been positioned to your specification, you can save a Video Position Preset that would allow you to restore this video position at a future time. Saving a video position preset is done by pressing Ctrl+"0..9", where "0..9" means a number between 0 and 9 in which to save the preset to. To restore a video position preset, simply press the number (again, 0 to 9). You can also modify video position presets through the "Advanced Options/Playback/Video/Presets" dialog.
To switch between windowed mode and fullscreen without losing the video position, press "Z" instead of Alt+"Enter".
Video Blanking Presets:
Video blanking is a feature that allows you to blank-out the left/right/top/bottom sections of the screen. It is mainly used to blank-out badly encoded DVDs where part of a widescreen video was encoded with gray borders instead of black. To activate a blanking preset, simply press Shift+"0..9". You can also modify video blanking presets through the "Advanced Options/Playback/Video/Presets" dialog.
Custom Aspect Ratio Presets:
Zoom Player has several aspect ratio modes, one of them is the "Custom" aspect ratio mode. Custom Aspect Ratio Presets allow you to specify different values for the "Custom" aspect ratio mode. You can modify custom aspect ratio presets through the "Advanced Options/Playback/Video/Presets" dialog. To activate a custom aspect ratio preset, simply press Alt+Shift+"0..9".
Color Control Presets:
Zoom Player allows you to save up to 10 different color (Brightness/Contrast/Saturation/Hue/Gamma) presets. You can modify color presets through the "Advanced Options/Playback/Video/Presets" dialog.
