2. What is PGS and SRT subtitles?

PGS subtitles – The .sup file extension stands for subtitle bitmap image extracted from a Blu-ray movie; it contains subtitle text graphics that are displayed during movie playback. The .sup subtitles are encoded with PGS codec, and sometimes known as PGS subtitles. Blu-ray PGS subtitles is not so widely supported by HD media players as DVD subtitles and usually need to be converted to more common subtitle format like SRT, SSA, IDX, ASS, etc. When a Blu-ray is ripped into .m2ts streams, the .sup subtitles can be extracted by demuxing the M2TS using tsMuxer. SRT subtitles – The .srt is primarily associated to DivX, DVD and some other video formats (e.g. MKV) as external subtitle format. SRT files are text files used in video playback. Therefore, they do not contain any video data, but they include the time each subtitle should be displayed followed by the text of the subtitle.
