### QA checks for captions



To further improve the quality of your subtitle translations, consider using the following QA checks:



- [Line Count Check](https://store.crowdin.com/line-count-check): Ensures that your translations maintain a controlled number of lines.



- [Maximum Reading Speed (WPM) Check](https://store.crowdin.com/maximum-reading-speed-check): Checks the words per minute in your translations to ensure captions are readable.



- [Characters Per Second (CPS) Check](https://store.crowdin.com/characters-per-second-check): Maintains a controlled number of characters per second to improve the readability of subtitles.



These QA checks are particularly useful for integration as CaptionHub controls these limits to ensure your subtitles meet the required standards for line count, WPM and CPS.



### Previewing video in the Editor

Consider using the [Video Preview](https://store.crowdin.com/preview-video) application to embed the video that's being translated directly into the editor to improve the translator's experience and the expected quality of translations.
