About SubCaptioner's Editor
To get started in the editor, upload your audio or media file to play alongside the text. Then, begin reviewing the text block-by-block to check for any spelling mistakes or words that the ASR technology may have misinterpreted. To make edits easier, the SubCaptioner editor provides a color coded system to show where errors may have occurred.
Once you're done editing, simply publish the new, edited version and download your files on the projects page.

We understand that your file and payment safety is incredibly important. We use a secured payment system through Stripe to ensure that your payment information is secure and encrypted. Media files processed by SubCaptioner are deleted once your caption or transcription files have been created and are never seen by anyone other than the ASR technology.
Yes, a minimum charge of $1 US (or equivalent) applies to all transactions – the equivalent of 4 minutes. If you have media files under 4 minutes, we recommend uploading multiple videos to the same cart before checkout.
When checking out, you will be given prices in US Dollars ($), Euros (€), or British Pounds (£) depending on your location.
SubCaptioner supports MP3, WAV, MP4, WMV, and MPEG1 as input files. For output files, we provide SRT and WebVTT subtitle/caption files as well as TXT transcript files.
Our maximum input file size is 1GB with a maximum duration of 120 minutes. If your video is over 1GB but less than 120 minutes long, we recommend you convert the file into an mp3 prior to upload.

Try out SubCaptioner for FREE with a US$10 free credit (equivalent to 40 minutes of free transcription/captions) when you create a new account. No payment card is required to access this free credit. To use the credit, simply upload any media file up to 40 minutes long (or multiple files adding up to the equivalent length). Adding translated subtitles will deduct the free credit total at an additional $0.25/minute. Your free credit never expires, but cannot be used as a part payment for larger files.
There have been cases of users not being able to log in to their SubCaptioner account due to Bitdefender blocking their access. We recommend deleting Bitdefender from your computer if this problem occurs and using a different cybersecurity software.
How SubCaptioner creates up to 99% accurate captions and transcripts
An SRT file (caption file) breaks down the speech into time stamped caption boxes. When added to a video file, these captions display text as it coordinates with the speech. A text transcript file simply breaks down the speech into text blocks based on speaker changes or pauses/utterances. SubCaptioner also provides the option to translate these captions and transcripts into a foreign language.
Although SubCaptioner's ASR technology can achieve up to 99% accuracy, small errors may occur when the audio contains loud background noises, multiple speakers talking at one time, or speakers with strong accents or mumbled speech. SubCaptioner's editor gives users the opportunity to quickly make edits to their text files in order to easily fix minor errors and improve the accuracy of their captions and transcripts.
