Videolinq is the first streaming service that support live stream of video with closed captioning from pre-recorded files. Watch a webinar about this feature (11 min.)

Feature Service Explained:

The video source for a channel must be MP4 files. You can stream single, or multiple files listed in a playlist. Add closed captioning to the file(s) by preparing a WebVTT (.VTT) file, uploading it, and associating each caption file with a media file. Use this tool to convert your captions file to VTT format. All Videolinq plans include a 5 GB free storage. Contact us to increase capacity.

Important: for closed captioning to work over the video, the MP4 and VTT files must use the same name during the upload process.

  • This will work - myfile.mp4, myfile.vtt

  • This will not work - myfile.mp4, filename.vtt


Open the channel and add a new video source.


Give the source a name, check the file source, and upload a file from your computer. Only MP4 and VTT files are allowed, at a maximum of 4 GB size, per file. Buy more storage space.


After the file(s) are uploaded, click on the Source icon on the left navigation bar and enter the Media Files and Playlists section.

In the Media Files & Playlists section you can:

  • Upload and rename files.

  • Drag and drop files to re-arrange their order.

  • Click on the + sign to associate a VTT file with a MP4 file.

  • Click on the file checkboxes to create and label a playlist.

  • Re-sort the order of files in a playlist.


This is how a closed captioning file will show association to a media file.


To create a playlist, check file records, type a name and click "Save".


Playlists will appear on the right side. Expand the playlist to rename it or re-arrange the order of files on the list.


To assign a file or a playlist to the video source go back and click on the 3 dots.


Select from the drop down a playlist or file and click on "Update".


Remember to enable the video source, and click "Go Live".

STEP 10:

Your channel is now active. Add new destinations or create a player.

Tips & Tricks: Automate the start and stop time of your live broadcast by using the Scheduler. If you are not using a scheduled broadcast, stop the broadcast manually when it end. Live streams from a single file, or a playlist, will continue streaming in a loop until stopped.
