How to Add Subtitles to a Video:Three Methods Compared

Quick answer: choose the subtitle format first

Burned-in subtitles are part of the picture and cannot be toggled off in the player. A separate subtitle file is loaded by the platform or player. Exact support varies by destination.

Method 1: Generate subtitles from speech

1. Import the video and choose the current transcription/automatic subtitle feature.
2. Generate subtitle text and timestamps.
3. Review each line against the audio, especially names, brands, numbers, specialist terms, and accented speech.
4. Adjust line breaks, size, color, position, and other available styling.
5. Preview subtitle timing with the picture and sound.
6. Export a subtitled video or obtain a separate subtitle text/file, depending on the destination.

Automatic recognition creates a draft; proper nouns and difficult recordings may be wrong. Review each line before publishing.

Method 2: Upload a separate subtitle file

A separate subtitle file generally contains text and timing information and is loaded by a platform or player. It can suit toggled captions, multiple language versions, or content that may be revised after publishing.

Check the destination’s current accepted file types and timecode requirements before export. A plain transcript may not contain subtitle timing. If the platform requires a specific format, use a tool that supports it and review synchronization after upload.

Method 3: Add subtitles by hand

Manual entry can work for a short clip, designed title cards, or a small number of corrections after automatic transcription. Typing a long video line by line makes omissions and timing errors more likely. You can create a draft automatically, then correct or reorganize it.

Burned in or separate?

Check what the destination actually requires. Do not assume one platform supports the same formats or display workflow as another.

Make subtitles readable on a phone

• Preview at the target phone size, not only on a desktop monitor.
• Place text where it does not cover the subject or platform controls.
• Break text into readable phrases and avoid too many lines at once.
• Make sure text contrasts with the background.
• Check that each subtitle appears and disappears with the speech.

Safe areas and design rules vary by platform and aspect ratio; preview on the destination before publishing.

Add subtitles in the tool you already use

For a third-party editor, check the current official help to confirm whether speech recognition, timeline editing, subtitle styling, and export formats are available in your version or plan. Exact menus and limits can change across platforms and plans.

In Aixcut, imported video can be transcribed into time-coded captions and reviewed line by line in the text panel. The text and style can be adjusted. Hiding the subtitle track produces an export without subtitles. Subtitle text can be copied or downloaded as TXT; users can request SRT/VTT in the chat and receive a download link. Subtitle translation supports any language.

Translate subtitles into another language

Review the source-language subtitles first, then translate the lines. Check names, brands, and context; sentence length can change in another language and affect reading time. Preview the translated video again and adjust timing or line breaks. Check the destination’s current rules to see whether multiple subtitle tracks are supported or separate video versions are needed.

Common mistakes

1. Publishing automatic subtitles without review. Check names, numbers, and specialist terms first.
2. Covering the picture or platform controls. Review on the target device and destination.
3. Treating a plain TXT file as a timed subtitle file. Confirm the output includes the required timing and format.
4. Skipping the exported version. Check visibility, synchronization, and cropping.
5. Translating before correcting the source subtitles. Fix the source text first to avoid carrying errors across.
6. Not reviewing timing after editing. After changing duration or clip order, preview the subtitles with the video.

Frequently asked questions

How can I add subtitles to a video?

Import the video and generate or enter the subtitle text, review its wording and timing, adjust the style, then either burn subtitles into the video or export a separate subtitle file as required by the platform. Preview the video and subtitles together before publishing.

Where can I get subtitles for a video for free?

Check the current caption tools on the publishing platform or a subtitle product with a free tier or trial. Free access, export formats, video limits, and commercial terms vary; consult the specific product’s latest official information.

How do I add subtitles to a video on my phone?

Use an editing or subtitle app that currently supports video on your phone. Select the video, generate or enter subtitles, review timing, and check the export. Follow the app’s latest official guidance for controls, formats, and plan limits.

How do I add subtitles to a video that doesn’t have any?

If the video has no subtitles, use automatic transcription in a tool that accepts video input to create a draft, then review each line and export it. You can also enter subtitles manually. Confirm whether the tool provides editable transcript text, a timed subtitle file, or a video with burned-in subtitles.
