Users will be able to understand and find your video more easily if you add captions or subtitles to each video file you've uploaded. To add captions or subtitles to one of your videos, log in to your Video Status page and click "Add Captions/Subtitles" in the "Actions" column for the selected video.
We currently support a simple subtitle format that is compatible with the formats known as SubViewer (*.SUB) and SubRip (*.SRT). Although you can upload your captions/subtitles in any format, only supported formats will be displayed properly on the playback page.
The supported format consists of text divided into separate caption (or subtitle) segments, in chronological order. Each caption must have three parts: a timecode, the caption text, and a blank line.
- Timecode: Specifies when the caption should be shown, and for how long. Time is measured from the start of the video in these units:
- HH - Hours starting at
00 - MM - Minutes (
00-59) - SS - Seconds (
00-59) - FS - Fractional Seconds (
0-999)
HH:MM:SS.FS,HH:MM:SS.FS- Caption display starts at the first time, and stops at the second time. This is compatible with the SubViewer format.HH:MM:SS,FS --> HH:MM:SS,FS- Caption display starts at the first time, and stops at the second time. For complete compatibility with the SubRip format, a "subtitle number" can also precede this timecode.HH:MM:SS.FS- Caption display starts at this time, but no stop time is defined. We'll try to figure an appropriate stop time.
- HH - Hours starting at
- Caption text: One or more lines of text. This text must be UTF-8 encoded so that any language can be supported.
- Blank line: a blank line is used to mark the end of each caption.
0:01:23.000,0:01:25.000
Text shown at 1 minute 23 seconds into the video, for 2 seconds
0:02:20.250,0:02:23.8
Text shown at 2 min 20.25 sec, until 2 min 23.8 sec
0:03:14.159
Text shown at 3 min 14.159 sec for an undefined length of time.
If your uploaded captions/subtitles are not available for online playback after a few hours, they may be in a format we don't support, or there may be something wrong with your encoding.
