Captions & Subtitles
Subtitle formats, timing rules, styling, accessibility compliance, and workflows for managing captions across multiple languages.
Subtitles fail for reasons that are specific and measurable, which makes them one of the few parts of video production where the right answer can be checked rather than argued about. These eight articles cover that ground. Two are about the file: what SRT, VTT and ASS can each express, what disappears when you convert between them, and the separate question of whether captions should be rendered into the picture or delivered alongside it — a choice that decides who controls their appearance, how many exports a language costs, and whether the text can be read by anything other than an eye. Two are about the numbers: reading speed, minimum duration, line length and where to break a line, and the styling techniques that keep text legible against footage you cannot predict. Two are about the work: a systematic method for repairing automatic captions, with an error taxonomy and a correction order, and the naming, locking and quality-assurance sequence that keeps eight language versions from drifting apart. The remaining two handle the choices people make by imitation — when word-level kinetic captions help and when they actively hurt comprehension, and what published accessibility standards actually ask a caption to contain, which is more than the dialogue. The articles describe standards and practices rather than giving legal advice. Throughout, the emphasis is on what a reader can verify: character counts, durations, contrast, cue boundaries, and the specific places automatic systems get things wrong. If you read one first, make it the timing article — reading speed is the measurement almost nobody checks and the one viewers feel most.

Managing Subtitles in Eight Languages Without Losing Track
One language is a task and eight is a system. The failures at scale are version drift, unlabelled files and timings that stopped fitting after translation — none of which are translation problems.
Captions and Accessibility: What Compliance Requires
The published accessibility standards do not ask for a transcript pasted under a video. They describe an equivalent experience, which changes what a caption has to include and how accurate it has to be.
Word-Level and Line-Level Captions: When Each Wins
One style reveals words as they are spoken, the other presents a complete phrase and holds it. They suit opposite viewing situations, and using the wrong one is a comprehension problem rather than a taste problem.
A Systematic Way to Fix Bad Auto-Captions
Automatic captions are wrong in specific places rather than randomly, which means they can be repaired methodically instead of read end to end. This is the error taxonomy and the correction order that goes with it.
Caption Styling That Stays Legible on Every Background
Caption legibility is not a font choice, it is a separation problem: the text has to survive whatever the footage does behind it. Four techniques, when each is the right one, and how to size type against the canvas rather than your monitor.
Burned-In Captions vs Soft Subtitles: The Real Trade-Off
Open captions are pixels and closed captions are data, and that single difference decides who controls the appearance, how many exports you need, and whether the text can be read by anything other than an eye.
Caption Timing Rules That Make Subtitles Readable
Subtitles fail on timing far more often than on translation or styling. This covers the reading-speed budget, minimum and maximum durations, where to break a line, and what to do at a shot change.
SRT vs VTT vs ASS: Which Subtitle Format to Use
SRT, VTT and ASS are not three quality tiers of the same thing. They are three different answers to the question of who decides how the text looks, and the answer determines where the file will work.
