Occlusion and Foreground Guide

Video Inpainting When Objects Cross the Mask

Published August 3, 2026 ยท Reviewed against Wipe AI product facts

Direct answer: An occlusion occurs when one object passes in front of another. If a foreground subject crosses a watermark mask, the repair must preserve that subject while also estimating the hidden background, making motion boundaries and identity details critical review points.

Find every crossing

Scrub the complete marked range and flag frames where faces, hands, hair, products, text, or vehicles enter the selection. A mask that is harmless over a wall can become destructive during a crossing.

Split time ranges or reduce the mask when the mark disappears. Do not sacrifice meaningful foreground detail simply to maintain one permanent rectangle.

Inspect boundaries and identity

Research on occlusion-aware video inpainting emphasizes shape, appearance, and motion-boundary consistency. In delivery review, watch for missing fingers, warped facial edges, duplicated texture, or an object that changes shape.

Treat labels, scores, prices, license plates, and safety information as semantic content. Do not approve generated details as factual recovery.

Choose a safer alternative when needed

A clean source, alternate angle, tracked patch, or deliberate replacement graphic can be safer than synthesis across a complex crossing. Sometimes leaving the mark is the most honest choice.

Document which frames were changed and why. Keep the original so reviewers can distinguish recorded content from reconstruction.

Recommended workflow

  1. Locate all foreground crossings through the mask.
  2. Classify whether identity or factual detail is at risk.
  3. Use the narrowest time-specific selection.
  4. Review motion boundaries frame by frame.
  5. Reject misleading reconstruction and preserve the original.
Source-first alternatives: Use an alternate take, clean plate, source project, tracked patch, intentional cover graphic, crop, or no edit.

Sources and further reading

Document the finished edit

Keep the untouched source, decision notes, and approved export together. Record why the edit was authorized, which time ranges changed, and which source-first options were checked. The intended task for this page is: Informational: evaluate occlusion and foreground crossings during video inpainting.

Before delivery, verify duration, aspect ratio, audio sync, and every repaired boundary in the real viewing environment. Wipe AI accepts MP4, MOV, WebM, AVI, and MKV, then exports H.264 MP4 up to 1080p. It processes one video at a time; results depend on overlay size, motion, and background complexity, and output may be re-encoded.

Frequently asked questions

What is an occlusion?

It is a visual overlap where one object hides part of another.

Why are hands and faces high risk?

Small shape or identity errors are noticeable and can change meaning.

Should one mask cover the whole clip?

Only if its footprint remains necessary and safe across every frame.

Can inpainting recover factual hidden detail?

No. It produces estimates, not evidence.
