You send the final captions, then hear back that every line arrives a little late. The words are correct. The problem is that your recipient paired them with a video that has a longer introduction.

Subtitle delivery is partly a version-control task. Matching filenames, a short delivery note, and a check in the destination player help prevent a good track being attached to the wrong recording.

This checklist starts before the export and ends after the upload. Use it when handing files to an editor, a client, or a teammate who was not there when the captions were made.

Agree on the delivery requirements

Ask the recipient which file format their player accepts, which language label they expect, and whether they need a separate track or captions rendered into the picture. Ask whether there are specific accessibility or style requirements. Do not assume that a subtitle file will carry the fonts and animations visible in your editor.

Freeze the video revision

Finish the picture and audio edit before making the final subtitle export. Record the video filename and runtime in a delivery note. If the video changes later, reopen the caption review rather than treating the old track as automatically valid. Even a short added title sequence can move the entire caption track.

Use a delivery folder

interview-v3.mp4
interview-v3-en.srt
delivery-notes.txt

This is a suggested naming example. In the delivery note, identify the language, video revision, subtitle format, reviewer, and any unresolved issue. Keep obsolete drafts out of the folder sent to the recipient. A clear folder is easier to audit than a message containing several files called “final.”

Check timing at meaningful points

  1. Check the first spoken words after the opening.
  2. Check a phrase immediately after an edited section.
  3. Check a passage near the middle.
  4. Check the last spoken sentence.
  5. Watch the entire delivered video with captions enabled.

Use the spot checks to identify where a mismatch begins. If every checked phrase has the same offset, compare opening sequences. If captions agree initially and fail after one edit, compare revisions around that edit. If the difference grows, compare the exact media file and runtime before applying a correction.

Review readability separately from spelling

Watch at the size viewers will actually use. Look for a caption disappearing before you can read it, a long phrase covering an important visual, or a line break that separates a name or tightly connected phrase. Rework the segmentation where needed while preserving meaning. Any numerical line or speed targets should come from the destination's current requirements.

Make acceptance explicit

CheckPass condition
PairingVideo and subtitle belong to the same revision.
LanguageThe track's text and platform language label agree.
ContentReviewed names, numbers, and final corrections are present.
TimingThe full destination playback has been reviewed.
AppearanceCaptions remain readable without obstructing key content.

After upload

Check the uploaded video through the viewer-facing player. Confirm that the caption selector exposes the correct track and that the first and last phrases appear correctly. A local preview does not prove that a platform accepted or enabled the uploaded track. Record who performed the final check and retain the delivered files.

Continue with Descript subtitle export, Happy Scribe subtitle export, or the SRT format guide.
