Hi. I'd like to share with you a site that talks about captioning. If someone is interested in creating a movie or a short film, you should read this blog: Subtitle Editor Currently there is only one official version of SE for Windows, however, for the various platforms there are also several quite interesting alternatives that you can use. See here on our site how to download Subtitle editor for Windows, Mac, Linux, Android or IOS. Find the links on our download page.
