About SUB_MICRODVD
MicroDVD is a frame-based subtitle format, which means its timings are based on video frame numbers rather than timestamps. For example, a line might be defined to appear from frame 1000 to frame 1050. This can be very precise, but it also means the subtitle file is tied to a specific video file with a specific frame rate. If the frame rate changes, the subtitle timing will be incorrect.
About VTT
WebVTT (Web Video Text Tracks) is the modern standard for displaying subtitles on the web, designed specifically for use with HTML5 video. It's similar to SRT but includes added features for styling (using CSS), positioning, and metadata. This allows for more dynamic, accessible, and richly formatted captions and subtitles directly in the browser.

Frequently Asked Questions
Why use frame numbers instead of time?
Frame-based timing can be very useful for video editors who work on a frame-by-frame basis. However, for general distribution and playback, time-based formats like SRT are much more flexible and reliable, as they are not dependent on the video's frame rate.
What happens if I use a MicroDVD file with the wrong frame rate video?
The subtitles will go out of sync. For example, if the subtitle file was created for a 25 fps video, but you play it with a 29.97 fps video, the subtitles will appear progressively earlier or later as the video plays.
How is VTT different from SRT?
The main differences are that VTT supports styling, positioning, and metadata, while SRT does not. VTT also has a slightly different timestamp format (using a period instead of a comma for milliseconds) and requires a 'WEBVTT' header. VTT is the standard for modern web video.
Can I use HTML tags in a VTT file?
You can use certain HTML-like tags within VTT cues for basic formatting, such as <b> for bold, <i> for italic, and <u> for underline. You can also define more complex styles in an external CSS file linked to the video player.
