In this article you will learn how to set up the subtitle preset and optimise spotting rules for subtitling square video. The configuration of subtitle presets is available for users with account owner or production admin priviledges.
By default, the subtitling and spotting rules used by Limecraft Flow are optimised for creating subtitles on horizontal videos (16:9). In this article you will learn how to optimise the subtitle settings and spotting rules for subtitling so that they fit on vertical videos.
A vertical video is a video created either by a camera or computer that is intended for viewing in portrait mode, producing an image that is taller than it is wide. Because of this tall image, you need to adjust the settings to ensure a good readability. You need to have less characters on one line and have more lines visible on the screen.
We recommend creating a dedicated Subtitle Preset for vertical videos.
Note that the cell resolution settings discussed below are only visible when you export subtitles in EBU-TT-D format.
Below you find our recommendations for the subtitle preset settings for vertical video (aspect ratio 9/16).
To begin, go to the production settings, subtitle editor and create a new subtitle preset for vertical videos.
Preview Aspect Ratio
The black box that you can see in the Region Configuration settings is your preview window. Change the aspect ratio of the preview in the lower right corner of the box.
Adapt the region settings to determine where on the screen your subtitles are shown.
There you’ll see “Bottom Region” and “Top Region”. We recommend using, 80% width and 13-15% height (for both) and to try if these fit your content. You can drag the Bottom region and top region position to a desired position in the preview window.
3. Characters on a line and number of lines
Lower on the page, you will find the Automatic Subtitler Spotting Rules section.
It is recommended to change the Character limits according to below:
The amount of characters on a line: at most 25 characters (hard limit 29 characters)
The number of lines: 3 lines (hard limit 4 lines)
