Adding captions (subtitles) to your videos significantly increases audience reach, and means your video complies with international accessibility guidelines.
9 out of 10 videos views online happen with the sound turned off. That's 90% of your potential viewers that are likely to ignore any video that does not have captions. Adding captions means that they can receive your message and continue watching your video with the sound off.
Complying with international accessibility guidelines also ensures that your video messages can also be watched and understood by people who are deaf or hard of hearing.
How to add captions to your video
1. In Brivvio review-mode, tap the 'Add Captions' button at the top of the view. This button looks like a speech bubble with a '+' symbol inside.
2. In the panel that appears tap the 'Generate Captions' button.
3. A pop up will advise you how long caption generation is estimated to take. You can close this pop up and continue to edit your brand preset or video format while captions generation takes place.
While captions are being generated, the 'Captions' button will contain a spinning wheel instead of the '+' symbol.
When your captions have been generated, a second pop up will notify you, and the 'Captions' button will contain two rows of broken lines (representing captions).
After captions have been generated, they will appear across the bottom of the video, in time with any spoken word in the video.
How to edit captions
Automatic captions generation is usually about 90% accurate, depending on audio quality, background noise, and clarity of speech. There is often a little editing to be done to get them 100% accurate.
To edit your captions:
1. Tap the 'Edit Captions' button (after captions have been generated)
2. Then tap the 'Edit Captions' link. This will open the Brivvio Captions Editor.
3. Scroll up and down the text of your captions, tap to place the cursor and edit using the on-screen keyboard.
4. When you are finished editing, tap the 'Save' link and playback your video to see your edited captions on the video in real-time.
Useful Tips: You can split a caption in two, by placing the cursor where you want to split it and tapping 'Return' on the keyboard. You can join two captions by placing the cursor at the start of the second caption and tapping 'Backspace' on the keyboard.
Best practices guidelines
Avoid splitting lines where you have added new words to the start or end of a caption.
Brivvio keeps the time-stamp for each caption line, so if you start adding words at the start or end of a caption, and then split the line on words that have been added, the new added words may display incorrectly because they don't have any time-stamp associated with them.
