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

STEP 1:

Open the channel and add a new video source.

STEP 2:

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.

STEP 3:

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.

STEP 4:

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

STEP 5:

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

STEP 6:

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

STEP 7:

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

STEP 8:

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

STEP 9:

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

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.
