How To
How to Export Video Captions as an SRT File
Export your captions as a standard SRT file for YouTube, Vimeo, and any platform that supports external subtitles.
Step-by-Step Instructions
- 1
Transcribe your video with AI
Upload your video to VideoCaptions.AI and run cloud AI transcription. The AI generates word-level timestamps for every spoken word — this precision is what makes the exported SRT file highly accurate.
- 2
Review and edit the transcript
Check every caption for accuracy before exporting. Fix typos, proper nouns, and misheard words. Adjust the grouping of words per caption block if needed. A clean transcript produces a clean SRT file.
Tip: SRT files are read by viewers more carefully than burned-in captions since they tend to watch longer-form content. Invest the extra minute to review every line.

Export as SRT from the export dialog
Open the export dialog and select SRT file format. The tool generates a standard SRT file with accurate timing codes for each caption block. Download the file and upload it to YouTube, Vimeo, Wistia, or any platform that supports external subtitle files.
01
SRT Files: What They Are and When to Use Them
SRT (SubRip Text) is the most widely supported subtitle file format in the world. It is a plain text file containing numbered subtitle blocks, each with a start time, end time, and caption text. The format is simple by design: it was created in 1997 and has remained the standard ever since because its simplicity makes it compatible with virtually every video platform and player. An SRT file looks like this in plain text: each block starts with a number, followed by a timing line like 00:00:01,500 to 00:00:03,200, followed by the caption text, then a blank line before the next block. When should you use SRT instead of burned-in captions? Use SRT when you are uploading to a platform that renders subtitles server-side and gives you styling control, like YouTube's subtitle manager or Vimeo. Use SRT when your content will be translated into multiple languages and you want separate SRT files per language. Use SRT when accessibility compliance requires toggleable captions that viewers can enable or disable. Use burned-in MP4 when you are posting to social media platforms that do not support SRT upload, when you want full control over visual styling, or when you need the same caption look across every platform without relying on the platform's subtitle renderer.

SRT vs. VTT vs. SBV: Understanding Subtitle File Formats
SRT is the most universal format, but several others exist and are required by specific platforms. VTT (Web Video Text Tracks) is the standard format for HTML5 video players and is used by Wistia, JW Player, and some streaming platforms. VTT supports basic styling tags that SRT does not, including color, position, and alignment. SBV (SubViewer) is the format required by YouTube's legacy subtitle upload system. YouTube now accepts SRT, VTT, and several other formats, so SBV is rarely needed. ASS and SSA are advanced subtitle formats used in anime fansub communities that support complex styling, but they are not widely supported by mainstream platforms. For most creators, SRT covers 95% of use cases. If a specific platform requires a different format, most online tools can convert SRT to VTT or SBV in seconds. VideoCaptions.AI exports standard SRT files with millisecond-accurate timing derived from word-level AI timestamps, making the exported file compatible with YouTube's subtitle manager, Vimeo, Wistia, and any other platform that accepts the SRT standard.

SRT (SubRip Text) is a plain text subtitle file containing numbered caption blocks with start/end timestamps and text. It is the most widely supported subtitle format and can be uploaded to YouTube, Vimeo, Wistia, and most video platforms. SRT captions are separate from the video and can be toggled on or off by viewers.
In YouTube Studio, open your video, click Subtitles in the left menu, select Add language, click Add under Subtitles, and choose Upload file. Select your SRT file and YouTube will parse the timing and text automatically. The subtitles appear in your video's subtitle track once saved.
Both work on YouTube. Burned-in captions look exactly as designed — your custom fonts, colors, and animations are preserved. SRT files use YouTube's default caption styling but are toggleable by viewers and can be translated. For creator-branded content, burned-in captions give better visual control. For accessibility and multilingual audiences, SRT is more flexible.
Yes. Vimeo accepts SRT files uploaded through the video settings panel under Subtitles and Captions. The timing from VideoCaptions.AI's word-level transcription produces highly accurate SRT files that align precisely with the spoken audio on Vimeo.
