How to Write Subtitle Guidelines for Your Team: A Practical Template

If your team produces video content regularly, you need subtitle guidelines. Without them, every editor makes different decisions about spelling, punctuation, speaker labels, and timing, resulting in inconsistent quality that reflects poorly on your brand. Well-written guidelines ensure that every subtitle file meets the same standards, regardless of who created it. This article walks you through the process of writing guidelines that your team will actually follow.

Why subtitle guidelines matter

Subtitle guidelines serve several important functions. First, they ensure consistency across all your video content, so viewers do not notice jarring differences in style or accuracy between videos. Second, they speed up the review process, because reviewers know exactly what to look for rather than evaluating each subtitle file on an ad hoc basis. Third, they make training new team members much easier, since the guidelines serve as a reference document that explains your team's standards. Finally, they reduce the back and forth between editors and reviewers, since everyone is working from the same rule book.

Key sections every guideline should cover

Your subtitle guidelines should cover several essential areas. Start with tone and voice, explaining how formal or casual the subtitles should be, and how to handle slang, idioms, and colloquialisms. Next, define spelling and grammar standards, including whether to use British or American English, how to handle numbers and dates, and when to add punctuation. Include speaker identification rules, specifying how many speakers you label and how you format those labels. Add timing and reading speed requirements, setting maximum characters per line and minimum display duration. Finally, include styling specifications covering font, colour, positioning, and background treatment if you produce ASS files.

Dealing with non-speech audio

Non-speech audio like music, door slams, and car horns are crucial for accessibility, but including them in subtitles can be subjective. Your guidelines should specify which sounds to include and how to format them. Generally, include music that is thematically important or sets the mood, but skip brief background music that is not meaningful. Use square brackets or parentheses to set off sound descriptions, and keep them short and action-oriented. For example, [door slams] or [crowd cheers]. Be consistent with the level of detail, and err on the side of inclusion rather than omission, since missing important audio cues can confuse viewers.

Quality control and review process

Even with guidelines in place, human review is essential. Your guidelines should specify a clear review process with defined roles. One team member should generate the subtitles, a second reviews them against the guidelines, and a third does a final quality pass. Use a checklist approach, with reviewers verifying that each guideline has been followed. Document common mistakes that your team keeps making, and update the guidelines to address them explicitly. This iterative process means your guidelines improve over time, becoming more precise and easier to follow as issues are identified and resolved.

Template for your own guidelines

When writing your own subtitle guidelines, start with these core sections and adapt them to your team's needs. Define your tone and voice standards, set technical specifications for line length and timing, establish speaker identification and non-speech audio conventions, and create a review checklist. Keep the document concise enough that team members will actually read it, but detailed enough that it eliminates ambiguity. Review and update the guidelines every few months based on feedback from your team.

Getting started

To create consistent subtitles, upload your video to Subify and let automatic processing convert the spoken content to text. Review and edit the generated subtitles, then download your SRT or ASS file. The Free plan includes 10 minutes of processing per month, which is enough to test your workflow and refine your guidelines. For ASS files with full styling control, upgrade to a paid plan.
