#VIDEOJS FRAMEBYFRAME UPDATE#
It is not enough for frame-accuracy: 25fps means an update every 40ms. It might seem marginal, but the post production industry needs frame accuracy.ĭue to browser limitations, timeupdate (event fired when the playing position of a video has changed) is fired every 150-250 milliseconds. Subtitles in the fixed video disappear right before the change of plan: Problem is that default HTML5 video's refresh rate is too low: subtitles appear and disappear too late creating a poor viewer's experience (and a non-broadcast compliant one).Įxample below higlights the issue. Subtitles follow the same rule : in and out timecodes are frame accurate (ex: 00:00:23:22 -> 23 seconds and 22 images).īrowsers process videos with millisecond timestamps, that's why subtitles have to be converted based on video framerate: for video at 25 images per second the previous timecode would look like 00:00:23.880 in milliseconds format ( 1000/25 * 22 = 880).įrame accuracy is really important : subtitles need to disappear right before the next cut and appear right after the previous one. In the post-production and broadcast industry videos are processed frame by frame.
