About
In Kaltura's Video Portal, you can upload caption files for any media that you own or have editing privileges to. The Video Portal supports SRT, DFXP, or VTT file types. You can add multiple captions files to each entry, for example, subtitle captions in multiple languages, and label each language.
For media files that don't already have captions, learn about generating captions in our article Order captions and enrichment services for media.
