How to remove a fly that crosses the shot for a split second
Tell Vizard Agent there is a fly to remove. It steps through the clip frame by frame to find every frame the fly is in, including blurred passes a quick review misses, then covers each one with background taken from the nearest clean frame, aligned and colour-matched, on that frame only.
What do you type into Vizard Agent?
Say roughly when you saw it, but ask for every appearance. A fly is on screen for a few frames at a time, often as a blurred streak, and the pass you didn't notice is usually the one left in the finished video. Vizard Agent treats finding every frame as the main job.
Remove the fly that flies through the video. Check the whole clip, not just the first time it appears.
What does Vizard Agent actually do?
It uses the neighbouring frames as the clean background, because a fly has moved on by the next frame. The hard part is finding every frame it touches, since a sampled review can easily step over it. In the session behind this article it:
- Had the six-second clip reviewed for insects, which found one pass at about 1.5 seconds, then pulled every frame around it at full resolution.
- Asked for a full frame-by-frame review, which still reported one pass, then stepped through the end of the clip itself and found a second, motion-blurred pass on three frames near 5.2 seconds.
- Patched all eleven affected frames from the nearest clean frame, aligned on a seam in the floor by template matching and colour-matched around the patch, each on its single frame only.
- Compared before and after strips, found a faint trace left on one frame, and widened that patch.
- Confirmed the audio was unchanged and had the floor reviewed again at both moments: clean, with no patches flashing.
When does this not work well?
When the fly lands on something that moves, like a face or a hand. The next frame then shows a different background behind it, so there is no clean patch to borrow, and the fix needs a generated repair or simply cutting those few frames.
Common questions
Why did a quick check miss it? It was a blur for three frames. Vizard Agent steps through every frame.
Does it touch the rest of the video? No. Vizard Agent patches only the frames with the fly.
What about other insects? Vizard Agent removes them the same way, if clean background exists.
