This open-source, R-based web application allows the conversion of video captions (subtitles) from the Web Video Text Tracks (WebVTT) Format into plain texts. For this purpose, users upload a WebVTT file with the extension .vtt or .txt (examples available here and here). Automatically, metadata such as timestamps are removed, and the text is formatted into a paragraph. The result is displayed on the website, and can be downloaded as .docx and .txt documents. Overall, this application serves to improve the accessibility of video captions.

Code details

The core of the application is in the index.Rmd script, which uses ‘regular expressions’ to process the VTT file. In turn, that script draws on another one to enable the download of .docx documents. Last, the latter script in turn uses a Word template.
