WebVTT (.vtt) Files

The WebVTT format (Web Video Text Tracks) is a format intended for marking up external text track resources. HTML5 standard uses it to display captions in synchronization with a video or audio material in the user's web browser.

WebVTT exported from EZTitles support vertical subtitles and ruby characters.

Although, by specifications, WebVTT shall be delivered as Unicode UTF-8 encoded files, you can change the output's file code page:


Allows you to Recut/Offset the subtitles during the export. This may be required for subtitle projects that do not start from 00:00:00:00, they are offset by an hour or more. Most video players assume the video always plays from 00:00:00:00 which creates synch issues with subtitles that are offset.

From the drop-down menu you can choose between the following options:

None - doesn't recut or offset the subtitles and they will be exported with their original timing.

Manual - allows you manually specify the offset for the recut.

Auto - automatically offsets the timing using the first subtitle's In-cue. All timecodes are offset backward with the first subtitle's In-cue rounded down to the closes hour. For example if the first subtitle originally starts at 10:00:32:21 after applying the recut it's start time will become 00:00:32:21.

Programme Start TC - automatically subtracts the value of the Programme Start TimeCode metadata parameter if available in the input file. Note that this parameter is supported for EBU STL, EBU-TT, EZT or EZTXML file formats only.

Video Start TC - automatically gets video's start time from the input EZT or EZTXML file and uses it to recut/offset the subtitles.

Horizontal position

Activating this option saves the exact horizontal position of the text using the "align" and "position" attributes.

Vertical position

WebVTT specifications allow vertical position to be represented in two different ways- by specifying the display line from the bottom or top of the picture or by setting the exact offset in percent.

Escape Right-to-Left and Left-to-Right marks

Right-to-Left and Left-to-Right marks can be "escaped" by inserting their hexadecimal codes according to the selected Unicode (UTF-8, UTF-16)  code-page: LRM and RLM.

If non-Unicode code-page is selected, then the default "&lrm" and "&rlm" escape codes will be used.

Write subtitle numbers as cue identifiers

Saves subtitle numbers in the output WebVTT file as cue identifiers. Indexes (1a, 2c, 3b, etc) will be discarded and the output will be renumbered automatically.

Export in Bold

Exports all subtitles text as bold.

Export CSS Style

Saves color information inline, as CSS style, into the exported WebVTT file's header.

Export Comments

By clicking this option the comments you have added to your subtitles will also be exported in the output file.

Export Zero Subtitle

Click it if you want to include the zero subtitle in the exported file.

Note: Background color will be exported automatically as long as the Background color is configured. Subtitles with box effect applied are not considered as subtitles with background.
