BoxCast gives you the ability to have automated captions appear on your live broadcast giving your viewers the opportunity to use watch with captions both during the live broadcast and once it is archived.

Be aware that live captions are not available on all plans. If you do not have this feature on your current plan and would like to add it, please reach out to your client manager or email CM@boxcast.com.

Step 4

Once the broadcast has ended you can review & edit the created captions. Simply click the text to change what you want it to say. Play using the player on the right, and watch as the blue line tracks through and highlights the caption that is currently being played. This is the best way to review an entire broadcast. Click the Play button on each line to skip to that part of the broadcast.

Review Warnings

From our automated caption creation, we are able to understand where there was uncertainty about whether the generated words are correct or not. The captions with higher uncertainty are shown as a warning in red. We recommend that you review every line, but if you are limited on time start by editing only the captions with higher uncertainty first. You can filter to only show these by clicking the settings icon in the top right corner then selecting "Review Warning Only" of the editing tool. Please do note that there

Find and Replace

Within the settings, you will also see a Find and Replace Tool. We recommend using this for names and other proper nouns or other uncommon words. When captioning our own Webinars, we often have to change "Box cars" to "BoxCast."

Edit Timestamp

This allows you to control when a caption shows up on the screen.

Add a Caption

You can add a new line at the end of the list of captions by selecting Insert Cue.

Step 5
When you are finished editing, you can click Publish. It will take a few minutes for those captions to process be live for your viewers in the BoxCast Player. Feel free to leave the page. No further action is required to push those captions live.

Common Questions

Can viewers turn on/off the captions?
Yes. There is a CC toggle to enable/disable captions in the player.

How can I improve the quality of the automatically generated captions?
The quality of the captions is determined by the quality and clarity of the audio input. A single speaker with a good microphone will perform well, but a crowded room with multiple speakers and on-camera audio will be much harder for the automated caption tool to pick out the right words. You can also add custom vocabulary (IE: the name of your organization or city.)

Do the captions show up on the BoxCast.tv App for Apple TV, Roku & FireTV?
Yes!

Can I edit the captions?
You cannot edit the captions during the live event, but you are able to edit the captions after the broadcast with our caption editing tool.

Can I add Captions Automatically to a recorded broadcast?

Yes! Check out this article to learn more
