What is an SRT file and why it matters
An SRT file is a plain-text subtitle file that contains time codes and the text shown on screen. It helps viewers follow dialogue and makes video content accessible. You can create an SRT file from audio or video by starting with a transcript or an existing subtitle file, then refining the text to match the spoken content and timing.
Two practical paths: transcribing from audio/video vs translating an existing subtitle
Many creators begin with a transcription from the raw audio or video track. The transcription becomes the basis for an SRT file, which can then be timed to screen captions. If you already have a subtitle file in another language, you can translate it into SRT for your target language and adjust timing as needed. The goal is a clean, readable subtitle track that lines up with what’s spoken on screen.
How to build an SRT file in a simple workflow
- Start from a transcript or existing subtitle: either generate a transcript from the audio/video or use a file you’ve already created.
- Break the text into subtitle blocks: keep lines short, usually two lines max per block, and limit each line to around 35-42 characters. Short blocks improve readability.
- Check the timing: an automatic transcript already gives each block start and end times. Adjust blocks that appear too early or too late, especially around pauses and speaker changes.
- Review for accuracy: compare the SRT text with the audio, fix typos, and ensure names and numbers are correct. Adjust timing if subtitles run too fast or slow.
- Export as an SRT file: save your work with the .srt extension so it can be used with most video players and platforms.
Tips for accuracy and accessibility
- Use a clear, natural transcription style with punctuation that helps readers, like commas and periods, to guide reading pace.
- When multiple speakers appear, label speakers if your project requires it, then reflect those cues in the timing.
- If you’re translating subtitles, start from a clean source file and re-check every line after translation so meaning stays intact.
- Keep consistent formatting (line breaks, punctuation, capitalization) across the file for a professional look.
Working with Aivently: supported workflow and how to export
Aivently transcribes audio and video files up to 3 hours long into a timed transcript, so every line already has start and end times. You see the exact credit cost before the job runs. In the editor you can correct the text while the video preview follows the active line, and warnings flag overlaps, gaps, long lines and fast reading speed. Cue times stay as transcribed; the editor changes text only. Export SRT directly, or VTT, ASS, TXT or JSON. If you need the subtitles in another language, translate the SRT in the same workflow.
Troubleshooting common issues
- Timing drift: minor tweaks to start and end times can bring subtitles back in sync with speech.
- Unclear words: review unclear terms by listening closely and consulting context. If needed, ask for clarification or annotate for revision.
- Long lines: split long phrases into shorter blocks to maintain readability.
Next steps and practical examples
If you’re creating content for a global audience, translating to SRT in the new language may attract more viewers while keeping the original timing intact. Start by transcribing or translating, then refine, review, and export to SRT.
