Quick answers for the most common format-decision questions.
Can I convert DOCX to VTT?
Yes, but a valid VTT file needs timestamps and cue formatting. A DOCX transcript gives you the words, not the timing by itself.
When is VTT better than DOCX?
VTT is better when the transcript needs to appear as captions in a web video player. DOCX is better for editing and review.
Can I use DOCX as captions without converting it?
No. Video players need a timed caption file such as VTT or SRT, not a Word document.
