Once you’ve downloaded your closed caption file, you can easily upload this file alongside your video to any platform that you use for video publishing. On Youtube, for example, just look for the menu tab “subtitles” and you’ll be able to easily upload your SRT file here.

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.

Many video players (such as VLC) allow you to preview your video with captions from an SRT file such as that created by SubCaptioner. If you spot an error then the SRT file can be easily modified in any text editor. For more advanced editing and/or longer media files, we recommend a caption/subtitle editing software such as WinCaps.

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.

SubCaptioner is supported on the latest desktop versions of Chrome, Edge, Firefox, and Vivaldi. File upload capabilities may not be available on other web browsers such as Safari Mac OS. The use of mobile devices is not currently recommended.
