About manual cropping

When the provided media content does not match any of the provided aspect ratio presets, it is advised to use manual mode instead.

In order to do know how many lines need to be cropped, calculate how large the area is that has black bars.

For example, the Cinemascope 2.37:1 format distributed on a regular Blu-ray disc will have 200 lines on the Top and Bottom area that will need to be cropped out.

How to perform manual cropping
  1. Select one of the four sides where black bars are visible.

    Tip: As black horizontal bars are the most common occurrence in the world of media (when compared to vertical bars), it is advised to start cropping with the Top area and then the Bottom area. Only if no perfect fit frame can be reached, crop the side areas.
  2. Enter the number of lines that will need to be cropped out and confirm.
  3. Repeat for each side where black bars are visible, until a complete picture is formed on screen.

    Tip: If the provided content has subtitles hard coded into the black bars region, manually crop the picture to cut out as much as possible while retaining the area with subtitles.

    For example, crop out the entire top black bar, and crop out just enough lines from the bottom black bar to make sure the subtitles are still readable.
