AI subtitle tools can get you most of the way there, but a few manual tweaks ensure that your captions are flawless, readable, and on-brand. Follow this workflow to polish AI-generated subtitles:
- choose the right tool for editing
pick a subtitle generator with an in-browser editor, such as Capsai Auto Subtitle Generator, which lets you review and adjust text and timing immediately after transcription
link: https://capsai.co/auto-subtitle-generator - download your draft subtitle file
export the AI output as an SRT or VTT file so you can work in any subtitle editor or text tool of your choice - open the file in a subtitle editor
use free editors like Aegisub or Subtitle Edit for detailed control, or online editors built into tools like Kapwing for a simpler interface - correct misheard words and punctuation
play back each segment and compare the text; fix homonyms, industry terms, foreign names, and add commas, question marks or exclamation points for clarity - adjust timing and line lengths
ensure subtitles appear long enough for viewers to read but not linger so long they overlap; split long lines at natural pauses and keep each caption under two lines - apply consistent styling
choose a legible font size, color, and position; add a semi-transparent background bar if your videos have busy scenes - handle speaker changes and sound effects
add speaker labels (for example “Narrator:” or “Host:”) and caption essential sounds like [applause], [music], or [door creaks] for accessibility - perform a final quality check
watch the video with captions on mute and verify that every line matches the audio, timing feels natural, and there are no typos - export the finalized subtitle file or burn in captions
save your cleaned SRT/VTT for platforms that support subtitles or choose a burned-in render if you need captions embedded directly into the video - upload and test on your platform
on YouTube Studio, Instagram Reels, or any hosting service, add your subtitle file and preview the result to make sure formatting and timing remain intact
by combining AI speed with these manual editing steps, you’ll deliver perfectly accurate, accessible, and professional subtitles that boost viewer engagement and retention.
