Frequently Asked Questions
What is CPS and why does it matter?
CPS (Characters Per Second) measures how fast text appears on screen. Industry standards like Netflix require a maximum of 20 CPS to ensure viewers can comfortably read subtitles. Our analyzer flags any entries that exceed this threshold.
What is the maximum line length for subtitles?
Netflix and most broadcast standards recommend a maximum of 42 characters per line. Longer lines may be cut off on smaller screens or look cramped. Our tool flags entries exceeding this limit.
How is the quality score calculated?
The quality score starts at 100 and deductions are applied for issues: too-fast CPS entries, overlapping timings, lines exceeding 42 characters, and empty subtitle entries. A score of 80+ is considered good quality.
What are overlapping subtitles?
Overlapping subtitles occur when one entry's start time is before the previous entry's end time. This causes both subtitles to appear simultaneously, which is usually unintended and confusing for viewers.
