Some effect subtitles are delayed during transcoding playback

[mouxiaohao 1]

When the movie is transcoded and played, some special effects subtitles, such as pgssub, those that float in the air, have colors, or are like lyrics, will experience stuttering and delayed disappearance, causing the subsequent subtitles to appear very slowly. However, after the special effects subtitles disappear, the originally delayed subtitles will accelerate back to the normal time axis until other special effects subtitles appear again, at which point they will delay once more. This is likely due to the problem of transcoding and compressing the special effects subtitles, resulting in an asynchronization with the video time axis. It should be ensured that the subtitle time axis is accurate through frame skipping or other methods.

It feels like the duration of the special effects subtitles has at least increased five to six times.
