Step 1 - Save Caption File
Once you have processed your video through SyncWords, open the Project Page and scroll down to the Select Output File Types section and check off and download a caption file. Vimeo supports the following captions and subtitles file formats: SRT, WebVTT, DFXP/TTML, SCC, and SAMI files, but Vimeo recommends using WebVTT whenever possible. Vimeo also recommends encoding your caption files in UTF-8 format. (Read how to change it here) Otherwise, captions that contain special characters may not display properly during playback.
See the Create a New Project and How to Output Captions on how to upload your media, customize your caption style, and save files to your local disc.

At this point, you can turn on any caption file you want to be available in the video.
