How to Edit SRT Timings in a Caption Editor (2026)

Editing SRT timings in a caption editor means moving the in and out of a cue until the words sit on the speech. A text box can fix a name. It cannot fix a line that shows up a second late.

Direct answer

1. Open the SRT next to the video, not in a notes app.
2. Play until a cue is early, late, or still on screen after the sentence ended.
3. Change that cue's start or end. Leave the rest alone.
4. Split a cue that covers two sentences. Merge a fragment that flashes.
5. Export SRT or VTT and spot-check one minute in the middle.

Three different timing bugs

People lose an hour by "fixing sync" on a file that only drifted in the middle. Auto captions do that. The open is fine. The section after the music sting is not.

Where to edit

In File Transcribe, signed-in Subtitles is the cue list, the video, and a timeline. Each cue has a start time and an end time. You can type either time, or drag the cue on the timeline. Drag the body to move it. Drag an edge to change the in or the out.

The row also has split (at the text cursor or the playhead), merge with the next cue, add, and delete. A cue needs at least two words to split. If there is no gap for a new cue, move an edge or split an existing one.

The no-signup subtitle editor edits cue text. It will not fix a late cue. If the bug is time, use Subtitles.

Importing an SRT does not transcribe the video. Uploading a video onto that caption file is playback only. The times you imported stay until you change them.

Export. SRT and VTT are on Pro, about $19/month, and Plus, about $49/month. Free is about 50 minutes a month, TXT or PDF. Confirm on /pricing.

Step 1: Find the first cue that is actually wrong

Play from a spot you know, not always from 00:00. Interviews go wrong after a pause, a laugh, or a cut.

Click the cue. You should land at its start. If the voice is already mid-word, the start is late. If the line is sitting on silence, the start is early or the previous cue ended late.

Step 2: Move one edge

Type a new start or end, or drag that edge. Arrow keys on the timeline cue nudge by a small step. Shift plus an arrow is a larger step.

Do not drag the whole cue unless the words are right and the whole line is simply shifted. Stretching both edges by accident makes a three-second sentence last six.

If two cues overlap, the editor keeps them from stacking on the same instant. Shorten one before you push the next.

Step 3: Split lines people cannot read in time

A cue that stays up for seven seconds of speech is usually two cues. Put the cursor where the sentence breaks, or park the playhead there, and split.

House defaults in the editor, which you can treat as a warning light and not a law:

• About 42 characters per line
• Two lines
• About 17 characters per second
• A cue shorter than half a second or longer than about 7 seconds

An amber mark on the row means one of those. The more useful version of the character rule is how many characters per line in subtitles.

Step 4: Merge flashes

A one-word cue that blinks is worse than a slightly long line. Merge it into the next cue when they are the same sentence. Read it once. If the merged line is now a paragraph, split at a better word.

Delete a cue only when the words should not be on screen: a false start you do not want captioned, or a duplicate the import created. Deleting dialogue because the time was hard is how captions go silent.

Step 5: Mark what you checked

The check on the row marks that cue reviewed. It does not change the time. Use it so a second pass does not re-edit the open. Unreviewed is the default after you change text or time, which is what you want. A time change means you should hear it again.

Step 6: Export and listen to the middle

Export SRT or VTT. Play one minute around the middle in a player that loads external subtitles, or upload to YouTube Studio and watch that minute on the video.

If the middle is late and the open was fine, you still have a drift, not a global offset. Go back to the first bad cue. Do not "nudge everything 200 milliseconds" and hope.

Studio is the right place for a two-line fix on a video that is already public. It is a poor place to rebuild timings for a long interview. That choice is caption editor vs YouTube Studio.

What a timing pass will not fix

A noisy mic, two people talking at once, or a name the draft spelled wrong. Those are text and audio problems. Moving the cue does not invent the missing word.

If the video also has to be readable inside a course player, the YouTube track does not travel with it. Students hitting a Canvas embed need the file or the player's own transcript: how to download a transcript from a Canvas embedded video.

FAQ

How do I edit SRT timings?

Open the SRT beside the video, change the start or end of the cue that is early or late, and export a new SRT. In File Transcribe that screen is Subtitles.

Should I offset the entire SRT?

Only if every cue, including the first, is off by the same amount. If the open is right and a later section is late, edit the later cues. A global shift will break the part that was already correct.

Can I fix timings without an account?

Not in the text-only subtitle editor. That tool changes words. Timings need the signed-in editor with video.

What does the amber mark mean?

The cue is outside the house limits: line length, characters per second, or duration. Read it out loud. If a person can read it before it vanishes, you can leave a mild warning. If they cannot, split or extend the cue.

Does editing the SRT change the YouTube video by itself?

No. Upload the new file in Studio, or replace the track that is already there. The editor does not publish to your channel.

Open Subtitles on File Transcribe, fix the cue you can hear is wrong, and export when the plan includes SRT or VTT.
