lostdistance has just created a new issue for https://github.com/w3c/webvtt: == Please define the presumed video frame rate == I often play media which does not include audio tracks or subtitles in my preferred language. My solution is to acquire standalone subtitle files from external sources. However, one omission from the SRT file format (used as the basis for WebVTT) is the presumed video frame rate. Without this, rendering software is provided no mechanism to automatically adjust timestamps as needed. Such a need arises when a subtitle file authored for one frame rate (for example, 24 fps) is to be rendered with media that has undergone standards conversion to another frame rate (for example, 25 fps). Without adjustment, the subtitles will progressively lose synchronization with the media. WebVTT defines timestamps but does not define the presumed video frame rate required to automatically adjust timestamps as needed. Please define the presumed video frame rate.
