Subly goes beyond basic auto-captions by ensuring complete accessibility and compliance with standards like EAA, WCAG, ADA, and ACA. It provides tools to edit and enhance captions and subtitles, customize their appearance, and translate them for a global audience. Subly supports detailed closed captions, including non-speech elements like sounds and actions, giving users ultimate control over their content. Additionally, Subly enables audio descriptions and color contrast adjustments, making it a versatile solution for companies aiming to cater to diverse needs. The platform's ability to generate detailed transcripts also aids in documentation, SEO, and content repurposing, making it an ideal choice for ensuring comprehensive accessibility in company calls, recordings, meetings, and events.

Auto-captions from Microsoft, Google, and Zoom are generated in real-time using their speech recognition technology during meetings, video calls, and webinars, providing basic accessibility features. However, these auto-captions often lack accuracy and control, potentially causing embarrassment to brands and individuals. They also fail to provide the detailed closed captions required by the deaf and hard of hearing, as they only capture speech and miss other important sounds like [door opening] or [dog barking]. In contrast, Subly offers a comprehensive solution by allowing users to upload or connect recordings from these platforms to generate complete transcripts, add and customize subtitles and captions, create audio descriptions, and translate content into multiple languages. Subly's AI-generated transcriptions and easy-to-use editor require no technical expertise, and users can collaborate with their team for improved accuracy or utilize Subly Human Services for professional assistance.

Subly offers transcription, translation and subtitle translation in 255 languages.

Once you've finished editing your video or audio file, simply click the download button in the top right and select the sizes and formats you require. You can download for use as open captions or closed captions by selecting MP4, SRT, VTT, TTML, or XML file formats. We also support TXT and DOCX files if you want to download the transcription only. Then, click download, and your files will download to your device.

Use Subly to merge SRT with MP4 online. If you already have an SRT file, you can add this to a video (.MOV or MP4) that you have uploaded to Subly.  Once uploaded you can edit if needed, or just use it as it is.  Just look for the tool icon in the editor screen to find the option to upload your own SRT file.
Once you download your video, it will have your SRT file burned into it unless you choose a different download option. Learn more about Subly's caption generator.

You can change the timestamps in the subtitle editor or on the video timeline. Easily add, edit or delete timestamps too whilst keeping them in sync.

We currently support .mp4 or .mov for video and any audio files. You can even upload your audio file, add an image to it and turn it into a powerful .mp4 file with subtitles. If your file format doesn’t match, you can use a free 3rd party converter. Learn more about converting audio to video.

Transcription accuracy depends on many factors. Our transcription is supported by Artificial intelligence (AI). Although AI technology has made huge advances in recent years, it is not optimal in every situation. The greatest factor of accuracy is the quality of the recording. If your audio has a lot of background noise the accuracy is likely to suffer. If there is little background noise, you use a professional mic for clear audio and one person speaks at a time, your transcription will be much more accurate.
