Currently, there are 2 mechanisms to associate captions with your media file (check here what media file types Windows Media Player supports):
1. Associate a SAMI file with your media file: learn here how to associate the SMI file with your media file. This is the most common method for captioning Windows Media. NOTE (2017): This method no longer works in some recent releases of Windows 10 + Windows Media Player 12. We recommend using VLC, along with a .srt file, to watch captions.
2. Open caption your media file: embed the caption file in an MP4/M4V media file. Since the latest versions of the Windows Media Player will play .mp4/.m4v files (not with closed captions, though), you just need to use our Video Encoding feature, and choose Open captions as the Encoding option.
With the first method described above, please note that captions must be enabled by the end user in the Windows Media Player:
- Make sure Windows Media Player is running in its own window, and not in the IE Media bar. To force Windows Media Player to use a new window, right-click the link and select Open in new window.
- Within the Player, choose the Play menu, then the Lyrics, captions and subtitles option, and make sure On if Available is selected.
- In Windows Media Version 10 and greater, you'll also need to open the Tools/Options menu, select the Security tab, and then:
- Check Show local captions when present. Click Apply.
- Exit the Player and relaunch for the changes to take effect.
Also, ensure the user is on the Now Playing mode, as opposed to the Library mode:
