Quick answer: To subtitle a video with AI, upload the video, choose the spoken language, generate a subtitle draft, review the wording and timing, then export a captioned video or a separate subtitle file. AI gives you a starting point; reviewing the result is part of the workflow.
How an AI subtitle generator works
Speech recognition turns spoken audio into text and aligns it with the video timeline. This reduces the need to type every sentence and time every subtitle manually. It does not guarantee that every name, accent or sentence will be recognized correctly. Background music, overlapping voices and unclear recordings can all make the draft harder to review.
See the automatic subtitle generator for generation, editing and export options.
How to subtitle a video with EasySub
- Start a subtitle project. Sign in to the subtitle workspace and upload a video you own or have permission to process. You can also use the YouTube URL import option for a supported, authorized source. If URL import fails, use an authorized local file instead; not every link can be imported.
- Choose the spoken language and generate. Set the language heard in the recording. If you also need translated subtitles, enable Add translation and choose the target language before generation. Leave translation off for same-language subtitles.
- Review the subtitle draft. Listen while reading the text. Correct names, numbers, punctuation and missing words, then check that each subtitle begins and ends with the speech. If translation is enabled, review both the original text and the translation.
- Choose your delivery format. Adjust subtitle styling and export a captioned video when the words should remain visible. Download a separate subtitle file when the destination supports an optional subtitle track.
What to check before publishing
- Meaning: Check negatives, names, amounts and technical terms. An illustrative example: “do not disconnect” and “disconnect” give opposite instructions. This is a proofreading example, not a measured EasySub result.
- Timing: Replay short phrases and pauses. A correct sentence is still difficult to follow if it appears too early or disappears too quickly.
- Readability: Preview the text against bright and dark scenes. Keep line breaks natural and avoid covering faces, important on-screen text or mobile interface controls.
- Accessibility: Review speaker identification and meaningful sounds where needed. Speech transcription alone does not guarantee complete accessibility captions.
Captioned video, subtitle file or plain transcript?
- Captioned video: Use embedded subtitles when the text should remain visible during playback, including on platforms without a separate subtitle track.
- SRT or VTT: Download timed text for a compatible player, editor or publishing platform. Check the destination’s accepted format before uploading.
- ASS: Choose this format for a compatible workflow that needs subtitle styling. Check how the receiving application renders it.
- TXT: Choose plain text for notes or a reusable transcript. This export does not include subtitle timing or styling.
When AI subtitles are useful—and where review still matters
AI can help creators prepare a first subtitle draft for interviews, lessons, tutorials and social videos. The useful outcome is an editable draft you can check and deliver, not a promise of perfect recognition or guaranteed audience growth. Start with a clear recording and review the exported result before publishing it.
