Getting started

Quick start

Create your first AI subtitles: upload a video, review the transcript, adjust the style, and export the result.

Reading time: 5 min

1. Open the editor

Open the Captions Space editor. Sign in or create an account if prompted.

2. Upload a file

Drop a video onto the upload area or click it to select a file.
Keep the tab open until the upload finishes.
Processing starts automatically after the upload.

3. Wait for processing

Captions Space transcribes the speech, aligns individual words, analyzes the frames, and prepares the initial subtitle design. The current stage is shown in the editor.

Do not upload the same file again while processing is in progress.
Processing time depends on video length and current service load.

4. Review the subtitles

Watch the video from beginning to end. Correct names, numbers, terminology, and speech obscured by background audio. Adjust cue text and timing where necessary.

Editing a word in the Scenes tab. Russian interface shown. Open the image to view it at full size.

5. Adjust the design

Choose a preset or configure the font, colors, outline, background, position, and animation. Check readability on both light and dark scenes.

6. Save changes

Click the disk icon in the top bar or press Ctrl+S (⌘S on Mac). The indicator marks unsaved changes. Wait for saving and subtitle rebuilding to finish; if saving fails, retry before closing the page.

7. Export

Choose MP4, MOV, H.265 or WebM for a finished video, or SRT, VTT or ASS for a separate subtitle track. Wait for preparation and click Download. Keep the tab open until you download a browser-generated MP4.
