Compared with embedded subtitles, inserted subtitles do much less harm to video quality. Plug-ins refer to subtitle files that run independently outside the video, which have little or no damage to the resolution of the video itself.
Embedding literally means re-recording a video with subtitles with proprietary recording software to become a new video; Although this method solves the problems of large video volume and player incompatibility, it will unconsciously destroy the code rate of the original video during the re-recording, making the resolution of the re-recorded video much worse than that of the original video. Therefore, when choosing plug-in and embedded subtitles, we should consider the video requirements according to our own situation.
