Questions
Frequently asked questions
Does TXT to SRT detect speech timing?
No. It assigns the duration you choose to each line; align the draft to audio in an editor.
What should each text line contain?
Use one short, readable subtitle per line for the cleanest draft.
Can I change the generated SRT later?
Yes. SRT is plain text and can be edited in subtitle software or a text editor.
