SRT can be imported as subtitle track and subtitle track can be exported as SRT,
The subtitle track can be converted to graphic text after version 23.1,
but it cannot be converted back. So it is one-way conversion.
The graphics panel in the text window can export the graphics text on the timeline to TXT and CSV only,
However, you cannot import the exported txt or CSV files back to Premiere,
And the txt timeline does not have a number like the SRT,
So How to use this function?
