Underword is a visual editor for subtitles in the WebVTT (.vtt) and SubRip (.srt) file formats.
To unlock the full potential of Underword, select a video to show alongside the editor. If you can open the video in QuickTime, you can open it in Underword. The subtitles will be visualized in real time on top of it. (The WebVTT format is interpreted differently by various internet browsers and video players. Please see the WebVTT help topic to learn how they are displayed in Underword.)
You can start creating subtitles from scratch, or by importing text (e.g. from a film script) that will be divided into subtitles which can then be adjusted.
The timeline view allows you to resize and rearrange subtitles with intuitive gestures. Dragged subtitle boundaries automatically snap to the timeline cursor and at a distance of 2 empty frames to other subtitles. Menu commands with keyboard shortcuts let you set the start or end time of the selected subtitle to the current video time. When setting the end time of the selected subtitle, the next subtitle is selected automatically, allowing you to adjust as many subtitles as you need in a single run.
Precisely control all the subtitle settings with manual text input. Toggle bold, italics and underline for the selected text range, or split the subtitle into two subtitles at the text cursor position. For an in-depth explanation of how the timeline, list view and video player work together, see Editing tools.
I created Underword because that‘s what I was searching for when creating subtitles for my own videos, but couldn‘t find an app that was easy to use, affordable and up to date. If you have any problem to report or a suggestion for a new feature, I’m always happy to help!
