Hands-on guides for creators, editors and educators: making subtitles, fixing them and getting them to look right on every platform.
· srt
Step-by-step guide to splitting an SRT file at a timestamp, merging several SRT parts into one, and combining two subtitle tracks — with the offset and renumbering rules that keep everything in sync.
· burn-in
The difference between hardcoded (burned-in) and soft subtitles, when to use each, and step-by-step ways to burn SRT or ASS captions into a video with FFmpeg, HandBrake or your video editor.
· vertical video
Best practices for captioning vertical short-form video: how many words per caption, reading speed, where to place captions to avoid app UI, and how to style them so they're readable on a phone.
· timing
Diagnose why subtitles are out of sync and fix them properly: shift all cues by a constant offset, stretch timing to correct frame-rate drift, and re-time individual sections after edits.
· subtitle formats
What SRT, WebVTT and ASS subtitle files are, how their syntax differs, what each supports for styling and positioning, and which one to use for YouTube, the web, video editors and burned-in captions.
· auto subtitles
A practical workflow for auto-generating subtitles from speech: preparing audio, choosing a speech-to-text tool, exporting SRT, and the editing pass that turns a rough transcript into readable captions.
