Start with the cleanest source
Keep the untouched file and note its duration, frame rate, and audio layout. Avoid unnecessary trims or frame-rate conversion during cleanup. FFmpeg documents that timestamp and frame-rate handling can duplicate, drop, or pass frames, which is why delivery QA must cover the full timeline.
Keep an untouched master before making any change. A project re-export, original camera file, removable subtitle track, or clean licensed asset preserves real pixels; inpainting only estimates pixels that are no longer available in a flattened frame. Document why you are allowed to edit the material and do not remove attribution or disclosure that must remain.

Plan a precise repair
Choose sync landmarks: a clap, lip closure, door impact, title cut, or beat. Record one early, one central, and one late event. If the video contains variable frame rate or previous phone edits, add more checkpoints around those transitions.
Scrub the complete clip, not just the first frame. Record when the visible element appears, moves, fades, or crosses a cut. Select the smallest region that fully contains its edge, shadow, and antialiasing. Split the work into separate time ranges when position or size changes; a permanently oversized region asks the model to invent unnecessary detail.
Review the difficult frames
Play through real speakers and headphones, then step through visible speech or impact frames. Distinguish constant offset from progressive drift: a constant offset is wrong everywhere, while drift grows over time and often signals timestamp or frame-rate handling.
Confirm duration, start and end points, channel audibility, and sync in the target browser or platform before replacing the original asset. Wipe AI accepts MP4, MOV, WebM, AVI, and MKV inputs and returns an H.264 MP4 up to 1080p. It processes one video at a time, and the result depends on the selected area, motion, compression, and background complexity. Watch the result at normal speed and frame by frame around cuts, foreground crossings, fast motion, and texture changes. Reject a repair that invents meaningful evidence, alters faces or captions that should remain, or creates a misleading impression of the source.
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 guide: verify and troubleshoot audio-video synchronization after authorized video cleanup.
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
Use visible and audible landmarks near the start, middle, and end. Matching only the first seconds cannot detect progressive drift.
No. It creates a plausible reconstruction from visible spatial and temporal context; it cannot reveal the exact covered image.
The current product output is H.264 MP4 up to 1080p, and processing can involve re-encoding.
No. Ownership, licensing, attribution, disclosure, privacy, and platform obligations still apply.

How the workflow works
Start with the original project when it is available. If reconstruction is needed, use the smallest area and shortest time range that contains the visible element.
What affects quality?
Camera movement, compression, scene cuts, detailed textures and subjects crossing the selected area all affect temporal consistency.
When should you use another method?
A clean re-export, source edit, crop, tracked patch or clean-plate composite may be more accurate depending on the shot.
AI reconstruction creates a plausible replacement from visible context. It does not recover pixels that were never visible in the source.
