What text can you remove from a video?

Start with the position and movement of the words. Separate SRT or VTT subtitle tracks can be disabled or removed directly; they do not need AI pixel reconstruction. The types below describe selection workflows, with recorded examples where available.

Burned-in captions and subtitles

Select the entire caption band, including outlines and shadows. Watch the tutorial comparison for two-line captions and bouncing word highlights.

Titles and headlines

Use a bounded selection for a fixed title. The city street example covers both headline lines; inspect the partly hidden sign and window edges. Edit source text layers directly when available.

Promotional and price text

Separate an upper offer label from changing lower copy. The UGC product example uses two regions on the same clip.

Dates and timestamps

A fixed corner date or recording timer fits a single box. Include the full footprint of every digit as it changes. The lab security-cam example uses an opaque OSD box over soft background.

How to remove text from a video in 4 steps

Confirm that the words are part of the picture, work from the best authorized source available, and review the complete result before publishing.

  1. 01

    Confirm the text is hardcoded

    Turn subtitles off in the player. If the words disappear, remove or replace the subtitle track; if they remain, they are part of the video pixels.

  2. 02

    Upload the best source available

    Use an owned, licensed, or explicitly authorized source with as little prior compression as possible. More real source detail gives reconstruction a stronger reference. Sign in to process and preview your upload.

  3. 03

    Choose the text removal scope

    Use sel_area (Box Select) for one stable caption band, multi_area (Multi-Box) for up to three non-overlapping boxes, or all_area (Full Frame) when text changes positions. Include outlines, shadows and the full bounce of highlighted words; check the estimate before processing.

  4. 04

    Preview, compare and download

    Watch the complete preview alongside the source. Scrub through caption changes, scene cuts and moving text. Check for residue, flicker and softened detail; adjust your selection if needed, then download. Output keeps the original audio and original resolution.

Real examples: remove text from video before and after

Compare six cases: tutorial captions, product copy, vertical creator captions, title text, a sticker label and a security-cam timestamp. Each 12-second comparison keeps the input and actual API output synchronized.

Demo overlays added to licensed footage; outputs come from the real API with no manual cleanup. These are examples, not a quality or speed guarantee.

AI caption remover for burned-in captions and subtitles

First check whether the words are burned into the pixels or stored in a subtitle track. Burned-in text can use one box, up to three non-overlapping boxes, or full-frame processing; removable SRT or VTT tracks do not need AI reconstruction.

Hardcoded captions are encoded into the picture. SRT, VTT, and other switchable subtitle tracks are separate data and should be removed or replaced without reconstructing the video.

Turn subtitles off first

If the words disappear in the player, edit the subtitle track instead of spending points on video cleanup.

Use a box for stable text

A fixed caption band, timestamp, or lower third usually needs only a tight region around its letters, outline, and shadow.

Treat moving text as a harder case

Animated words, scene cuts, and text crossing faces or fine detail require closer full-clip review.

Can I remove two-line, word-highlight captions from a video?

Yes, burned-in two-line captions with an active-word highlight can be processed like other video text. Cover the entire animated word area, including both lines, the active word’s bounce and outline. The 12-second tutorial and vertical creator examples below show actual API results. Check every word change for remnants and flicker; separate subtitle tracks should be removed directly.

Choose the cleanup scope before processing

The editor exposes three scopes instead of forcing every clip through the same workflow. It also shows the point estimate before the task starts.

  • Box Select — Target one predictable caption band, timestamp, or label. The standard web rate is 5 points per started 30 seconds.
  • Multi-Box — Mark up to three separate, non-overlapping text regions. The standard web rate is 10 points per started 30 seconds.
  • Full Frame — Process the complete frame when a bounded selection is not suitable. The standard web rate is 10 points per started 30 seconds.

Rates can change; check current point usage

Prepare a clean source master for the next edit

Text removal is most useful when it unlocks a specific revision. Keep required notices and ownership marks, and remove only the copy approved for replacement.

  • Replace burned-in captions — Clean an old caption band before adding corrected or translated subtitles.
  • Refresh campaign copy — Update an expired offer, product label, lower third, or approved sponsor line when the source project is unavailable.
  • Clean owned screen recordings — Remove temporary meeting labels, timers, notifications, or review notes from recordings you control.

After cleanup, continue with video translation

Caption replacement and localization. Prepare a source master for corrected captions, a new language, or a different subtitle style.

What makes video text removal easier or harder?

Text or sceneSelection approachWhat to inspect
Static text on a stable backgroundA tight sel_area boxLetter edges, shadows and repeated texture
Two-line or word-highlight captionsInclude both lines and the full animation footprintEach highlighted word and caption change
Separated labels and promo copymulti_area for up to three non-overlapping regionsEvery region, especially near hands and product contours

Faces, hair, fabric or fine patternsKeep the selection as small as practicalSoft detail, invented texture and altered contours
Camera motion, scene cuts or occlusionReview the complete processed intervalFlicker, smearing and texture that moves differently

Cropping changes the composition, while blur or mosaic leaves a visible patch. Inpainting attempts to reconstruct the selected pixels, but the result still needs review because hidden detail cannot always be recovered reliably.

Check the result before publishing

  • Play the complete clip at normal speed, then scrub through word changes and cuts.
  • Look for residual letters, shadows and outlines at the selection edges.
  • Check for blur-like softness, smearing, repeated texture and invented detail.
  • Watch for flicker, texture drift or a repaired area that lags behind the scene.
  • Compare faces, hands, hair, clothing and product contours with the source.
  • Check that text outside your approved cleanup scope remains present.
  • Listen to the original audio and confirm the downloaded video has the original resolution.

Frequently asked questions

How do I remove text from a video online for free?

Sign in to start with 10 free points. Upload an authorized video, choose Box Select, Multi-Box or Full Frame, check the point estimate, process and compare the preview before downloading. Processing and preview require login.

Can I remove text from a video without cropping it?

Often, yes. Box Select, Multi-Box, and Full Frame keep the existing frame dimensions while AI reconstructs the processed area. Review the full preview because motion, compression, and hidden detail affect the result.

Do I need AI to remove an SRT or VTT subtitle track?

No. If subtitles are stored as a separate SRT, VTT, or player track, disable or replace that track. AI cleanup is for words already burned into the video pixels.

What makes video text removal harder?

Fast motion, scene cuts, large text, heavy compression, flashing light, and text over faces or fine patterns leave less reliable background information. Use a tight selection and inspect the entire interval where the text appears.

What should I check before publishing the cleaned video?

Watch the full result at normal speed and scrub through every caption change and scene cut. Compare the selected area with the source for residue, flicker, repeated texture, soft edges, or changes near faces and objects.

What text should not be removed?

Keep attribution, provenance, ownership marks, safety labels, evidence, and legally required notices. Process only footage you own, license, or have explicit permission to edit.

What kinds of text can this video text remover process?

Burned-in captions, titles, lower thirds, date stamps, promotional copy, labels and sticker text can be selected for reconstruction. Use a region that covers the whole text footprint. The recorded examples show tutorial captions, promotional copy, vertical captions, titles, sticker labels and a security-cam timestamp.

Can it remove moving text or captions that change position?

The 12-second vertical creator example uses all_area for captions that move from the lower band to the upper band after eight seconds. Where possible, use a bounded region covering the text path. Review every position change and any text you want to keep.

Can I remove text from only one part of the frame?

Yes. sel_area targets one region, and multi_area supports up to three non-overlapping boxes. Use all_area for full-frame text removal when a bounded selection is unsuitable. Compare the whole result before downloading.

How long does it take, and how much does it cost?

Recorded 12-second API runs include USD 0.045–0.09 charges (caption and promo cases) and USD 0.05625 for later title, sticker and timestamp cases (15 billable seconds each). Processing times vary by clip. These are measured runs, not guaranteed turnaround times. Web points are separate: Box Select costs 5 points per started 30 seconds, Multi-Box and Full Frame cost 10. Check the pricing page and task estimate.

Will the video quality or audio change?

Output keeps the original audio and original resolution. AI reconstructs the selected pixels, so fine texture, motion and hidden details can still show artifacts. Compare the complete preview with the source before publishing.

Can I remove text from TikTok, Instagram Reels or YouTube Shorts videos?

Use an uploaded video you own, license or have explicit permission to edit. The vertical creator example demonstrates two-line highlighted captions for a Reels, TikTok or Shorts editing workflow. Inspect the complete result before adding replacement captions.
