8. Zoom Control
madVR Explained: These settings are used primarily with projector set-ups using Constant Image Height (CIH) projection. The projector device and screen size should first be defined in the devices section of the madVR control panel before adjusting these settings.
disable scaling if image size changes by only
If the resolution needs scaling by the number of pixels set or less, image upscaling is disabled and black pixels are instead added to the right and/or bottom of the image.
move subtitles
This is important when removing black bars. Otherwise, it is possible to display subtitles outside the visible screen area.
automatically detect hard coded black bars
This setting works in combination with a number of options as described below.
Black bar detection detects black bars added to fit video content to an aspect ratio other than the source or the small black bars left from imprecise analog captures. An example of imprecise analog captures includes 16:9 video with black bars on the top and bottom encoded as 4:3 video, or the few blank pixels on the left and right of a VHS capture. madVR can detect black bars on all sides.
if black bars change pick one zoom factor
Set to avoid changing the zoom or crop factor when the size of black bars changes frequently during playback. When set to which doesn't lose any image content, madVR will not zoom or crop a 16:9 portion of a 4:3 film . However, when set to which doesn't show any black bars, it will zoom or crop all of the 4:3 footage the amount needed to remove the black bars from 16:9 sections.
if black bars quickly change back and forth
This can be used in place of if black bars change pick one zoom factor. This option allows a limit on how often madVR can change the zoom or crop during playback to remove black bars as they are detected. Without either of these options, madVR will always change the crop or zoom to remove all black bars.
notify media player about cropped black bars
Define how often the media player is notified of changes in the black bars.
always shift the image
Determine whether the top or bottom of the video is cropped when zooming.
keep bars visible if they contain subtitles
Disable zooming or cropping of black bars when subtitles are detected as part of the black bar. Black bars can remain visible permanently or for a set period of time.
cleanup image borders by cropping
Crop additional pixels on the edges of black bars or on all edges. When set to crop all edges, pixels are cropped even when no black bars are detected.
if there are big black bars
Defines a specific cropping for large black bars.
zoom small black bars away
This removes black bars by zooming the video slightly. This usually results in cropping a small amount of video information from one edge to maintain the original aspect ratio and resizing to the original display resolution. For example, the bottom is cropped to remove small black bars on the left and right and the video upscaled to the original resolution.
crop black bars
Crop black bars to change the display aspect ratio and resolution. Cropping black bars increases performance as the pixels no longer need to be processed. Profile rules referencing resolution will use the post-crop resolution.
