Export the right deliverable
Use a separate subtitle file when your destination accepts a caption track. Export it from the same final edit as the video, then check both together in the destination player.

Your video looks finished in the editor. Then someone asks for an SRT file, and the captions you carefully styled are suddenly a different delivery task.
A separate subtitle track carries words and timings. The caption design you see over the picture may not travel with it. Before exporting, you need to know whether the destination wants a timed track or words rendered into the video.
Here we work through that decision, a small subtitle-file example, and the checks that catch a track exported from the wrong revision. Start with the final video and the destination’s accepted formats; those two details prevent a lot of unnecessary rework.
Start with the destination
A subtitle file and a video with visible text solve different publishing needs. If your destination accepts a separate caption track, export a timed file. If you need words permanently visible in the image, use a video-caption workflow instead. Decide this before exporting.
Choose the subtitle output
Descript supports separate SRT and VTT subtitle files. In the export workflow, choose the subtitle output and select the format accepted by the destination. The settings include speaker labels, a maximum character count per line, and a maximum number of lines per card. Set these for your reading context rather than treating the defaults as a universal standard.
Check the actual file
Keep the subtitle file beside the final video. Import both into the destination and watch a section with fast speech, speaker changes, and a cut. For a practical check, compare the first and last captions with the recording; a mismatched video edit can make an otherwise valid file drift.
If you expected styled text
A subtitle export is not a guarantee that the destination will reproduce your caption appearance. Test the final player. Keep an editable source so you can change line breaks without rebuilding the entire project.
Prepare the final recording first
Export the video and subtitle track from the same finished edit. A subtitle file describes when words appear; it does not follow a video automatically when you shorten the introduction or remove a sentence afterward. Keep a simple delivery folder containing the final video, its subtitle track, and a note identifying the language and revision.
A useful naming convention is interview-final-en-v2.mp4 alongside interview-final-en-v2.srt. This is an organizational suggestion, not a required Descript setting. Matching names make it easier to notice when a colleague uploads yesterday's captions beside today's video.
Choose the deliverable by destination
| Your destination | What to confirm before exporting |
|---|---|
| A platform with a subtitle upload field | Check its accepted formats and upload a separate subtitle file. |
| A social video that must show words everywhere | Check whether captions need to be rendered into the video image. |
| A website video player | Check the player's track format and language configuration. |
| A reviewer who needs readable text | Ask whether they need a transcript rather than timed subtitles. |
Inspect a small export before handing it off
The following original sample shows the structure you should be able to recognize in an SRT export. It is deliberately short so you can compare the words and timing by eye.
1
00:00:01,000 --> 00:00:03,000
Welcome to the interview.
2
00:00:03,200 --> 00:00:05,800
Today we discuss better captions.Each block has a number, a start and end time, and displayed text. The first sample remains on screen for two seconds. The second begins after a short gap. An SRT file is a text-based delivery format; the example does not contain video, a branded font, or animated text effects.
Review three points, then review the whole video
- Opening: check the first spoken phrase. An introduction added after export can shift every caption.
- Middle: check a phrase after a substantial edit. A mismatch that starts here suggests an older track or an edit made after the subtitle export.
- Ending: check the last sentence. A growing mismatch needs a different investigation from a fixed offset.
- Full playback: watch the final upload with its caption track enabled. Spot checks help locate problems but do not prove the entire track is correct.
What a subtitle file will not preserve
If your design depends on word-by-word animation, outline colors, or a specific placement, do not assume an SRT export will reproduce that appearance. Test the destination player. Keep the distinction between the words and timings in a separate track and the visual caption design rendered in the video.
Common delivery mistakes
- Sending a transcript document when the recipient asked for timed subtitles.
- Using captions generated before the final edit.
- Uploading the correct track with the wrong language label.
- Checking the editor preview but never checking the delivered file.
- Changing the filename extension instead of exporting the required format.
