Video Playback Aspect Ratio
Overview
Media Center offers several features for customizing the aspect ratio of video playback. These features are useful in several scenarios, including:
- You wish to crop black bars baked into a video
- A video has an incorrect aspect ratio due to incorrect encoding
- You use an anamorphic lens on your projector
- A television broadcast has artifacts encoded into the very edges of the video
Changing Settings
Aspect ratio controls are available from the right-click menu on a playing video under 'Window'.
It is also possible to toggle between several common aspect ratio configurations by using the 'Aspect Ratio' portion of the OSD.
Aspect Ratio Mode
The program will use one of the following modes:
Preserve Aspect Ratio: makes no changes to the aspect ratio, and shows black bars when necessary (the default mode) Crop: fills the screen with video by cropping away the portion of the video that doesn't fit Stretch: fills the screen with video by stretching, so the aspect ratio can be distorted Anamorphic: compresses the picture horizontally for expansion later by an anamorphic lens
Crop Black Bars
It is common for black bars to be encoded into a video. If you tell Media Center about these bars using this option, it can better deal with these videos.
Crop Black Bars preserves the aspect ratio. It zooms into the good / non-black-bar region of the movie.
The option 'Crop Sides of Video to Fill Screen' determines if it should zoom in until the black bars at the top and bottom are totally gone, even if it means losing a little of the sides of the video.
Crop Edges
This crops a little bit of the edges of the video. It is useful for HDTV broadcasts that contain visual artifacts at the very edge of the screen. This is common with ATSC broadcasts in the United States.
The amount of edge cropping can be configured in Options > Video and defaults to 2%.
Override Aspect Ratio
Sometimes a video may display with an incorrect aspect ratio. This can happen for a variety of reasons like a bad encoding, a display that stretches unexpectedly, etc.
In these cases, you can tell the program to force the aspect ratio to a particular value. If the option names don't make sense, just try each aspect ratio until one makes the video look better.
