There are two main ways to add subtitles to a video: burn them into the image ("hardcode"), or display them as a live layer over the player. Each approach has clear advantages. Here's how to choose.
Burned-in (hardcoded) subtitles
Here the subtitles become part of the image itself. The advantage: they'll work in any player, on any device, with no dependency on a separate file. The downside: you can't turn them off, change size or color, or fix a mistake without re-encoding the entire video.
Live subtitles as a layer
In this approach the subtitle stays separate from the video and is shown over it in real time. The advantage: full control — size, color, position, sync, and even switching language on the fly. You can fix a line instantly, and the fix improves next time. This is the approach that suits viewing and learning.
When each one fits
Burned-in subtitles suit cases where you need a single file that works everywhere — for example, sharing. Live subtitles suit daily viewing, language learning, and any situation where you want flexibility and quick fixes.
Pangea Player's approach
Pangea Player focuses on live translation: a subtitle you can adjust, sync, and correct — so the viewing is fully under your control, in natural language.
