Caption limits
Captions often have a technical specification, which is especially stringent in the broadcast and film industries. CaptionHub has a real-time QC feature: it continually checks that your captions meet the specifications that you define.
CaptionHub has the ability to store a default set of specifications for your Team, so you can set it once and then forget about it. The default limits are fine for most web applications.
By using limits, and as part of CaptionHub's real-time QC, we can identify whether each caption:
- Exceeds the number of permitted lines
- Lasts for long enough on screen
- Lasts for too long on screen
- Exceeds the number of permitted characters
- Maintains a specified distance (in frames) from its neighbours
- Exceeds the reading speed (measured as either Characters Per Second, or Words Per Minute)
To adjust the default settings, please click the Team menu in the sidebar and choose Team settings. The default limits can be adjusted in the Caption settings section.
Here you can make your caption limit selections. You can also disable all validation alerts for the second caption track, preventing errors and warnings from appearing for those captions by selecting Apply limits to T1 only. This prevents errors and warnings from appearing for the second track. If you want validation to run for both caption tracks, select Apply limits to T1 & T2.
In the caption editor, click on the caption limit exceptions filter to view all captions with issues:
