You have corrected the captions, and the video is ready for YouTube. Now the job is to pair the right text track with the right upload—not to generate everything again.
A small version mistake can undo a careful proofreading pass. If you shortened the opening after making the captions, the old file may no longer match. If you have only a transcript, it may still need timings before it can serve as a caption track.
This guide helps you prepare the file, locate the upload workflow, and check what viewers will actually see. Keep the final video and caption file together, and use YouTube’s linked instructions if the interface differs from the steps described here.
Prepare the file first
Check the spoken words against the recording, correct names, and ensure the timestamps match your final video. A caption file made for an earlier edit may drift after an introduction is trimmed or a section is removed.
Use a supported format. Our SRT guide explains the basic file structure; consult YouTube’s supported-format documentation for platform requirements.
Add the caption track
In YouTube Studio, locate the video through the Subtitles area, add or select the intended language, and choose the option to upload a caption file. Use the timed-file option for a file that already includes timestamps. Save the track, then check its availability and playback.
The exact controls can change. Follow the official YouTube instructions for the current sequence.
What if you only have a transcript?
A transcript without timestamps needs alignment. Do not rename a text document to .srt and assume it will become a timed caption track. Choose an available synchronization workflow, or create a properly timed file before importing.
Review the viewer experience
Watch the beginning, a middle section, and the ending. Check sync, spelling, and the selected language. Then review the full track for errors. Confirm you uploaded the caption file for this video rather than a similar recording.
When a separate tool may help
If you publish across several platforms, need editable transcripts, or want to reuse a recording as written content, a dedicated tool may be useful. Start with your required output and compare the export options before paying. See our workflow comparison.
You do not need to buy a tool simply to follow the upload workflow. Correct source text and a compatible file matter more than the brand used to create it.
