This guide addresses how to add closed captions to previously recorded video files. This walkthrough assumes that you have already successfully uploaded video content. If you need help adding video files to your DaCast account, though, please read our VOD Walkthrough.
First, to add subtitles, click on the video file you wish to modify. Go to the PUBLISH SETTINGS tab, which will give you a view like below:
Right below Autoplay is the "VOD Subtitles" option. This displays all current subtitles on the video file, and gives you the ability to add subtitle files. To do this, click the button. You will need to find WEBVTT (aka VTT files) or SRT files to upload.
If you don't already have them, these files are easy to create in a simple text editor.
Here are two examples for WEBVTT and SRT files:
WEBVTT Subtitle File Example:
VTT files are very easy to create using Notepad or any other plain text editor program. Below is an example of what a cue looks like for a VTT file. The first number is when the subtitle is supposed to appear. The second time stamp is when the subtitle is supposed to disappear.
00:00:06,000 –> 00:00:11,000
I hear there is a motion in the wind.
00:00:12,500 –> 00:00:16,500
Yes, I have heard it as well. Like a soft breeze of change.
00:00:18,500 –> 00:00:24,000
Isn't this example a little too poetic for subtitle creation?
00:00:25,500 –> 00:00:34,000
Very, but it still gets the point across.
If you want to use languages other than English, the VTT files must be saved using UTF8 encoding to have characters displayed properly.
SRT Subtitle Example:
Below is an SRT example. It functions similar to the time stamp method of the VTT files.
StartTime –> EndTime
00:15:25.000 –> 00:15:29.000
This is a test subtitle A
00:15:29.000 –> 00:15:32.000
This is a test subtitle B
The example above would make the first subtitle (test subtitle A) appear at 15 minutes, 25 seconds in video playback. It would disappear at 5 minute, 29 seconds exactly. The second subtitle (test subtitle B) would appear at 15 minutes and 29 seconds, and then disappear at 15 minute and 32 seconds exactly.
