FAB Subtitler BCAST/XCD can detect text inserts in the video and can then automatically apply a vertical offset to subtitles so that the subtitles do not cover the text insert in the video.

Configuration of video source

FAB Subtitler BCAST/XCD requires a video source, for example SDI for Decklink card input or live video stream received over udp. The configuration of live video source is described on this page this page.

Configuration of vertical offset

The configuration is available in Options / System / System settings:

• “0 lines from bottom” means that no vertical offset will be applied when a text insert is not detected.
• “Not more than 7 lines” means that when a text insert is detected a vertical offset will be applied so that the subtitle will not cover the text insert, but the offset will not be more than 7 lines.
