How to add subtitles to Instagram Reels.

Start with the same video.

Keep the original video you own or have permission to edit. Match it to the public Reel you transcribed: the same speech, clip order, opening silence, and playback speed. A Reel with a shortened introduction will have different cue times from your longer camera file. Finish major cuts before aligning subtitles.

If the Reel is already public, use its direct link in the transcript tool, review the result, and download SRT when available. The transcript download guide covers that step. Timed export depends on the segments returned by the transcription provider; timestamps are not guaranteed. When SRT is disabled, keep the TXT as a wording reference and create timing in your editor.

Trying to copy words that are already on a Reel? First identify whether you need the post caption, text on screen, or spoken audio in the guide to copying text from Instagram Reels.

Read one cue before importing.

Each SRT cue has a number, a start and end time, and the words to display. A blank line separates cues. In the example below, the first sentence starts half a second into the source video and ends at 2.3 seconds. Commas separate milliseconds in SRT timecodes.

1
00:00:00,500 --> 00:00:02,300
Keep the original video.

2
00:00:02,600 --> 00:00:04,600
Match each line to the voice.

3
00:00:05,000 --> 00:00:07,400
Watch the final export on your phone.

These lines and times were written for this guide. They are not a real Reel transcript or a claim about transcription accuracy. Download the sample to inspect its format; it will not match your video.

A plain transcript renamed from .txt to .srt is still missing the cue structure. Keep an untouched copy of a working SRT before editing it, and save text files as UTF-8 so accented characters and non-Latin scripts remain readable.

Import your SRT into the editor.

Create a project with your matching source video first. The routes below follow the linked official documentation, checked September 12, 2026; they are not a claim that we tested every editor version or account.

CapCut Desktop or Web

On Desktop, open Captions → Add Captions and select the SRT. On Web, open the left-hand Captions area and upload the caption file; its documented import format is SRT, not TXT. Imported cues become editable timeline text blocks. Select a block to adjust words, timing, and appearance. Follow the CapCut subtitle import instructions if your interface differs.

CapCut's current help page does not support direct SRT import on Mobile. Start this workflow on Desktop or Web. Do not assume that a file in your phone's Downloads folder can be opened as an editable caption track.

Adobe Premiere

Import the SRT as project media. Drag it from the Project panel into your sequence; Premiere creates a caption track. Align it with the matching footage and review the text. See Adobe's caption import guide for the documented process.

Fix the cause of a timing mismatch.

Play the first spoken sentence, a sentence in the middle, and the final sentence. This separates a constant offset from timing that drifts through the clip. An imported file can be structurally valid and still be out of sync with the video you selected.

Every line arrives equally late or early

Check the starting position of the subtitle track. For example, if the exported Reel omitted two seconds of silence that remain in your original file, move the entire subtitle track two seconds later. Confirm that the same adjustment fixes the beginning and end before moving individual cues.

The beginning fits, but later lines drift

Look for a speed change, removed section, or a different edit of the video. A single track shift cannot repair this pattern. Use the matching cut or retime the affected sections. Recheck everything after any further video edits.

Only one sentence looks wrong

Listen again and adjust that cue's in and out points. Split a long sentence at a natural phrase break instead of shrinking all the text. Check the next cue for accidental overlap or a gap that cuts off the thought.

Proofread names, numbers, negations, and words masked by music against the audio. Preserve what was said; do not silently replace an uncertain phrase with a guess. Speech transcription can omit useful non-speech information. If that information matters to understanding, add appropriate sound or speaker labels during your caption review.

Export the words into the picture.

Choose a readable type size and strong contrast, then preview over both bright and dark footage. Keep captions away from faces, important objects, and the outer edges where playback controls can cover them. Use short phrase groups that can be read while watching the action. A pleasing still frame is not enough: watch every transition at normal speed.

For this workflow, export a video with the subtitle text visibly rendered into its frames, often called burned-in or hard subtitles. Exporting only another SRT leaves you with a separate text file. Open the finished video outside the editor and confirm the words remain visible without loading any subtitle file.

Transfer that rendered video to your phone and review it at normal viewing size, with sound and muted. You can then use your usual Instagram posting process. Keep the project and SRT for corrections: once text is rendered into video frames, changing it requires another export. This process creates a new video file; it does not update an already published Reel.

Check the file you will actually use.
