Burned-in captions and closed captions are different deliverables.
Burned-in captions become part of the video image and are always visible. Closed captions stay as timed text that a compatible player can show, hide, and sometimes restyle. That structural difference matters more than what either option looks like in a preview.

The short answer
Choose burned-in captions when every viewer must see the same designed words in the same place. Choose a separate caption track when viewers need control, the platform accepts timed text, or the text must remain reusable for accessibility, search, correction, or translation. Export both when one video must work in a social feed and in a player with caption controls.
What burned-in captions are
Burned-in captions are rendered into the video pixels. They are also called open, hardcoded, baked-in, or hard subtitles. They survive reposting because there is no separate file to lose, and they can use precise typography, animated emphasis, and placement. The cost is permanence: viewers cannot turn them off, enlarge them independently, or replace them with another language without a new render.
What closed captions are
Closed captions are delivered separately from the picture, through a file or timed-text track the player understands. The viewer can normally enable or disable them. Depending on the player, a viewer may also adjust size, color, background, or language. Captions commonly include relevant non-speech information such as speaker identification, music, and sound effects, but a filename alone does not guarantee that editorial detail is present.
Why burned-in text is not a closed-caption track
A label in an editor does not change the delivery. Once text is painted into every frame, it cannot be toggled by the player and no longer exists as a machine-readable caption track. The FCC describes open captions as an integral part of the picture and closed captions as hidden until decoded. The modern web implementation differs from television signals, but the viewer-control distinction still holds.
Accessibility and the two-layer mistake
Always-visible text can help people watching silently, but it does not automatically replace a proper caption track. A separate track gives viewers control and preserves text for assistive and platform features. Publishing both on top of each other can also create duplicate overlapping lines when closed captions are enabled, so test the real player rather than assuming more caption layers are always better.
Choose by destination
A short social clip often benefits from burned-in text because the design remains visible during autoplay and after reposting. YouTube, course platforms, and web players can benefit from SRT or VTT because the player handles the track. Client review may use a captioned MP4 for visual approval and a sidecar file for final delivery. Ask what the destination accepts before doing the final render.
What Auto Subtitle Generator produces
The same reviewed project can export a watermark-free captioned MP4 and separate SRT, VTT, or TXT files. The MP4 is the burned-in route. SRT and VTT are timed-text routes for compatible platforms and players. TXT is a transcript without cue timing. An account is required to download, and free video export supports Clean Minimal and Documentary rather than every previewable premium effect.
When this tool is not enough
This product does not certify legal accessibility compliance, author broadcast caption formats, or verify a destination's ingestion rules. It also does not translate the transcript as part of this workflow. For regulated delivery, follow the receiving organization's specification and use a qualified captioning or quality-assurance process where required.
Frequently asked questions
Can viewers turn off burned-in captions?+
No. The words are part of the video image. Removing or changing them requires editing the source project or producing a new render.
Are SRT and VTT always closed captions?+
They are timed-text file formats that can carry subtitles or captions. Whether the content qualifies as captions depends on what the text includes and how the receiving player exposes the track.
Are burned-in captions accessible?+
They can make speech visible, but they remove viewer control and may not satisfy the requirements of a platform, institution, or law. Do not treat a burned-in MP4 as automatic compliance.
Should I deliver both MP4 and SRT?+
Deliver both when the designed always-visible version and a selectable text track serve different destinations. Avoid displaying both simultaneously if that creates duplicate overlapping captions.
Can burned-in captions be translated later?+
Not as text. You need the original transcript or a sidecar file, then translate, review, and render another version. Keep SRT or VTT as a reusable master when future languages are possible.
Does caption styling survive in SRT?+
Usually not. Basic SRT carries cue numbers, timing, and text, while receiving platforms choose how to display it. Burned-in output preserves the design because it is in the pixels.
