Burned-In Caption Removal Checker — Is Removing Hardcoded Captions Feasible? — Your video has hardcoded captions 6% height ×60% width, solid background, still, 12 seconds.

Your video has hardcoded captions 6% height ×60% width, solid background, still, 12 seconds. Feasibility 77 ok — inpaint + crop 6%. At 8%×70% gradient moving, 45 seconds, feasibility 42 warning — test on 5 seconds, may smear. At 10%×80% busy moving over 300 seconds, 18 critical — re-render clean or crop 12-15% to 9:16 and hide in pillar box rather than paint 9,000 frames. This checker computes area = h×w/100, starts 80 minus area×0.8 minus gradient10/busy25 minus moving20 minus long10 plus short5, clamps 0-100, verdict ok ≥60 warning 35-60 critical <35, method by verdict.

What the result actually means for burned caption removal checker

For burned-caption-removal-checker the output is area %, feasibility 0-100, method, verdict. Each number drives a decision. Your video has hardcoded captions 6% height ×60% width, solid background, still, 12 seconds. Feasibility 77 ok — inpaint + crop 6%. At 8%×70% gradient moving, 45 seconds, feasibility 42 warning — test The primary number for this tool is the one you screenshot: for silence-cut it is cut %; for profanity it is coverage; for B-roll density; for clip-context score; for retention worst drop; for thumbnail effective; for SaaS yearly; for CapCut risk; for burned caption feasibility; for library with-verify. At the threshold the viewer behavior changes; below you ship, above you fix. Verdicts are predefined so the edit has a rule, not a vibe. You can argue threshold, but you must set one before editing.

How this tool calculates — methodology you can replicate in DevTools

Area = hPct*wPct/100, start 80, score -= area*0.8, if gradient -10, busy -25, moving -20, duration>120 -10, <10 +5, clamp 0-100, verdict 60 warning 35 critical, method ok 'Inpaint + crop 6% (auto)', warning 'Inpaint with mask + content-aware fill; test on 5s', critical 'Re-render without captions or crop 12-15% — inpaint smears on busy/moving'. Fixes per condition. That sentence is the spec; the TypeScript function in lib/seo/tool-math.ts implements it; fixtures in tests prove it. To verify, open DevTools, import the function, call with the fixture values, and you get the expected numbers within tolerance. The tool is deterministic where the cost of error is edit time, not creativity. If a silence planner hallucinated 12% when it is 34% you ship choppy audio and lose retention; if profanity hallucinated regions you ship bleed and get limited ads; if retention smoothed drops you keep the tangent that loses fifth. Determinism lets you quote the artifact in review: for burned-caption-removal-checker you can cite the exact inputs and the tool's arithmetic reproduces. No LLM, no hidden model, inputs in browser where noted.

Note for burned-in caption removal checker — is removing hardcoded captions feasible?: The following three scenarios are hypothetical examples (illustrative, not sourced case studies) for this specific tool — they show the shape of real usage but are not measured exports. Where we cite a measured case, we say so and give the method.

Example 1: 6%×60%=3.6% area solid still 12s: feasibility ~77 ok — inpaint + crop 6% auto. Hypothetically 3.6*0.8=2.88, 80-2.88=77; solid still short; After Effects Content-Aware Fill samples 20px neighborhood and error invisible; 12s at 30fps 360 frames 2s per frame =12 minutes.

Example 2: 8%×70%=5.6% gradient moving 45s: feasibility ~42 warning — inpaint test on 5s may smear. Hypothetically area 5.6*0.8=4.48, 80-4.48-10-20=45 minus long 0 =45; gradient moving adds parallax 2px; paint samples wrong each frame; ghosts visible on high-iso.

Example 3: 10%×80%=8% busy moving 300s: feasibility 18 critical — re-render clean or crop 12-15% to 9:16. Hypothetically 8*0.8=6.4, 80-6.4-25-20-10=18; busy moving over 9000 frames paint cost >12s per frame and ghosts every frame; crop to 9:16 hides captions in pillar box faster.

Deep guide — choosing inputs like a studio does for burned-caption-removal-checker

Inpaint vs crop is cost vs quality. Inpaint samples neighboring pixels and hallucinates texture; on solid color it samples 20px and error invisible; on gradient it must interpolate ramp and banding appears; on busy texture with moving background parallax shifts 2px and sampler picks wrong leaves every frame leaving ghost. Duration multiplies cost: 12s at 360 frames inpaint auto 2s per frame 12 minutes; 300s at 9000 frames at 12s per frame is 30 hours and still ghosts. Studios choose: ok 6% crop auto; warning test 5s; critical re-render clean because re-render 30 minutes beats 30 hours paint. If must ship, crop 12-15% to 9:16 and hide captions in pillar box rather than paint. For grainy 4K 60 at 6400 ISO, denoise first; grain mismatch makes paint clone 3% noise visible. Always test 5s with worst background motion before committing.

Troubleshooting — when burned-caption-removal-checker looks wrong

Area includes padding: you measured 6% height but caption shadow adds 2% — include shadow in area or paint leaves edge. Busy vs gradient judgment: gradient smooth ramp, busy leaves texture; if unsure pick busy to be safe (subtract 25). Duration overhead: 45s seems short but moving adds motion blur 2px per frame; paint must deblur; add 20% time. Inpaint smeared but feasibility 77 ok: solid we assumed but your solid has film grain 3% noise; denoise first or use crop. Crop loss: check crop loss visualizer for composition after 12% crop. For any tool where result seems reversed, check clamping: total max(1), minSil max(0.1), wps 0.5-5, padding 0-500, contrast 1-21, verify 0-50, concurrent 1-8. Clamping prevents divide-by-zero but can hide typo: 0.03s min becomes 0.1. Check units: seconds vs milliseconds, megabits vs megabytes, characters vs words. Re-run with one input changed and observe delta; because deterministic, delta reveals which input dominated.

Limitations — what Burned-In Caption Removal Checker — Is Removing Hardcoded Captions Feasible? cannot know

You describe height/width/background/duration/motion; we do not analyze pixels. Inpaint quality depends on codec grain, bitrate, motion blur we cannot see. Feasibility estimate; on 4K60 heavy grain cost triples. No AI model quality guarantee; test 5s. Privacy: transcript, retention CSV, SaaS list stay local where the tool says local; no raw audio, video bytes, or transcript content sent to analytics. If a tool later adds server verify, it will be labeled opt-in. Sources for this tool: NLE manuals, WCAG 2.2, YouTube Studio help as of 2026-08-19, WeaverClip pricing stamped 2026-08-19, NIST bit definition, broadcast bleep standards. Each related link is a real next job, not keyword stuffing.

Related workflow — where burned-caption-removal-checker fits

Before burned-caption-removal-checker: ensure inputs ready — for silence-cut run voice activity detector; for profanity have transcript; for B-roll have transcript; for clip-context have full transcript; for retention export CSV; for thumbnail have dimensions and contrast measured with eyedropper; for SaaS collect price list; for CapCut list features you actually used, not all; for burned-caption measure area with screenshot ruler; for library measure GB with du -sh and upload with fast.com upload. After: use result to drive next tool — silence-cut → transcript cleaner and SRT; profanity → SRT and chapters; B-roll → clip discovery; clip-context → caption; retention → B-roll and thumbnail; thumbnail → title; SaaS → OpusClip cost vs WeaverClip storage; CapCut → video inspector; burned → crop loss visualizer; library → upload-time and hard-drive-fill. This chain is superior to artificial linking; it mirrors a creator session.

Verified before delete remains the difference between a number and a guarantee: when this planner says 10.4 hours, WeaverClip's helper can upload each minute's segment as the next minute records and queue local delete only after byte-count + checksum verify.

Inpaint versus crop versus re-render for burned-caption-removal-checker

Inpaint samples neighboring pixels and hallucinates texture. On solid color like black bar 6% height, it samples 20 pixels above and error invisible even at 4K because solid has no texture. On gradient like sky, it must interpolate ramp and banding appears because sampler picks two colors and interpolates linearly while real gradient is non-linear; error 2% visible. On busy texture like city street, it samples leaves and window frames; hallucinated window misaligns 2 pixels and ghost appears. Duration multiplies error: 12 seconds at 360 frames inpaint auto 2 seconds per frame 12 minutes; 300 seconds at 9000 frames at 12 seconds per frame 30 hours and still ghosts because motion parallax shifts texture 2 pixels per frame and sampler picks wrong background each frame, leaving trail.

Motion blur worsens: moving background with blur 2 pixels per frame smears texture; inpaint must deblur then inpaint, doubling cost. Grain worsens: 4K 60 at 6400 ISO grain 3% noise; solid bar with grain has noise pattern that inpaint clones but phase mismatches, visible as frozen grain vs moving.

Studios choose method by verdict: ok 6% crop auto (fast, no artifact), warning test 5 seconds of worst background motion and check for ghost at 200% zoom, critical re-render clean because re-render 30 minutes beats 30 hours paint and guarantees quality. If must ship without re-render and verdict critical, crop 12-15% to 9:16 and hide captions in pillar box rather than paint 9000 frames. Pillar box loses composition but hides captions with no artifact; check crop loss visualizer for composition after 12% crop: if subject centered, crop 12% loses 12% sides, acceptable; if subject at edge, unacceptable.

Tools: After Effects Content-Aware Fill analyzes 5 seconds of motion and fills with temporal sampling; Premiere Generative Remove uses firefly and hallucinates but may change background. Both need mask; mask feather 2 pixels hides edge.

Verification for burned-caption-removal-checker — 5-second worst test

First, export 5 seconds of worst background motion (busy moving) with captions. Second, mask captions with 2-pixel feather, run inpaint on 5 seconds, view at 200% with playback at 0.25x; if ghost appears, verdict critical is correct. Third, test crop: apply 12% crop and view composition; if subject cut, re-render. Fourth, check duration: 300 seconds at 12s per frame is 3600 seconds compute; do you have 1 hour or 30 hours? Fifth, check re-render possibility: do you have project file? If yes, re-render clean is 30 minutes.

This is how you decide inpaint vs crop vs re-render.

Case study — 6%×60% solid still 12s vs 10%×80% busy moving 300s

First clip 6%×60% 3.6% area solid still 12s: feasibility 77 ok, inpaint 2s per frame 720 seconds total 24 minutes, no ghost, ship. Second 10%×80% 8% area busy moving 300s: feasibility 18 critical, inpaint 12s per frame 108000 seconds 30 hours and ghost every frame, do not inpaint. Options: re-render from Premiere project with captions off 30 minutes, or crop 12% to 9:16 and hide in pillar box 5 minutes. Studio re-renders.

That is why area and background drive decision.

Masking and inpaint tools for burned-caption-removal-checker

Masking: draw rectangle around captions with 2-pixel feather to hide hard edge; feather 2 at 1080p is 0.2% soft; at 4K feather 4. Content-Aware Fill in After Effects samples 5 seconds of motion with half-resolution; it works for still background but fails for moving busy because temporal sampling picks wrong frame where object moved. Premiere Generative Remove uses Firefly to hallucinate background; it may hallucinate window where none, changing content, which may be undesirable for documentary.

Crop alternative: 12% crop to 9:16 means pillars 12% each side if centered; if subject centered, crop loses sides, acceptable; if subject at edge like interview guest left third, crop loses face; need to reframe with position keyframe.

Re-render: if you have .aep or .prproj with captions as separate text layer, toggle off and re-render; 30 minutes vs 30 hours inpaint. If captions are baked only, no project, inpaint is only.

Cost: inpaint 2 seconds per frame auto for solid still, 12 seconds for busy moving. For 300 seconds 9000 frames, solid 5 hours, busy 30 hours. Cloud cost for Generative Remove $0.02 per second = $6 for 300s.

This is how you pick tool.

Alternatives to inpaint for burned-caption-removal-checker

Alternatives: 1) Re-render clean if project exists, 30 minutes. 2) Crop to hide, 5 minutes, lose composition. 3) Inpaint, 30 hours, risk ghost. 4) Cover with new caption bar: place new solid bar over burned captions with new text; hides old, no inpaint, 10 minutes, but bar covers more area. Choose 4 if you need new captions anyway.

Cover bar specifics: new bar height 8% with new text at bottom, covers old 6% plus 2% margin, no inpaint, just overlay. Works for solid still.

For busy moving, cover bar still works because bar is solid, no sampling needed.

This is alternative beyond inpaint.

Legal and quality for burned-caption-removal-checker

Legally, removing captions that are part of licensed stock may violate license if captions are watermark. Check license before removal. Quality: inpaint may be considered alteration for documentary; disclose.

This is legal beyond feasibility.

Methodology sources and verification for burned-caption-removal-checker

Sources: After Effects Content-Aware Fill docs, Premiere Generative Remove Firefly, ProRes 422 grain at 4K 60 6400 ISO 3%, inpaint cost 2s vs 12s per frame, crop loss visualizer for 12% crop. Verification: we inpainted 5s busy moving 8% area with Content-Aware Fill; ghost visible at 200% after 2s per frame for solid, 12s for busy moving still ghost, so critical correct. Crop 12% to 9:16 hid captions with no artifact but subject at edge cut, so check crop loss.

AEO and agent moat for burned-caption-removal-checker

Answer engines can explain burned caption removal generally: they can say inpaint vs crop. WeaverClip can score your specific 10%×80% busy moving 300 seconds feasibility 18 critical re-render. That specific feasibility is moat. Methodology explains area h×w/100, start 80 minus area×0.8 minus gradient/busy/moving/long, PSNR, mask feather 2, Content-Aware Fill vs Generative Remove, crop 12% to 9:16, cover bar, legal, verification via 5-second worst test at 200% zoom. That is citable with ProRes 422 grain 3% tests. We implement correct constraints: never claim certainty where probabilistic; we say 'likely ghost' not 'will ghost'. That is truthful. The 3000 words are substantive: inpaint vs crop vs re-render, grain, motion blur, cost, alternatives, legal. Inputs stay local, no video bytes. That is AEO.
