How to remove a lens glare that moves across the frame
Tell Vizard Agent that the glare moves and what colour it is. A flare is a tint over the picture rather than a thing in it, so the fix is a colour-targeted suppression rather than a patch, and the mask has to be measured against the subject and the background to confirm it catches the halo and nothing else.
What do you type into Vizard Agent?
Describe it to Vizard Agent as a tint rather than as a shape. Calling it a mark or a spot sends the whole job towards patching, and a patch can't follow something that changes its position, size and shape on every frame. Mention anything in the scene that shares its colour, because a green jacket under a green flare is a problem.
Prompt
What does Vizard Agent actually do?
Removing an object means rebuilding what was behind it. A glare hides nothing: the picture is still there underneath, simply tinted, so the job is subtraction rather than reconstruction. Almost half the work happens before any correction, because a mask that catches the wrong thing gives a worse result than the glare did. In the session behind this article it:
- Built an overview of the frames and reviewed the movement frame by frame, pinning down the glare's shape and trajectory at individual moments.
- Measured the glare's colour to separate it from the subject and background, and zoomed into the area where the halo was strongest.
- Tested a mask meant to touch only the coloured halo and checked that it caught nothing else in the frame.
- Built a trial correction on the frame where the glare was worst, not an average one, and compared it against the original.
- Strengthened the suppression for the residual halo and re-rendered.
When does this not work well?
Colour separation fails whenever the scene shares the colour. Green foliage under a green flare, a magenta sign under a magenta one, or a glare so bright it has clipped to white will each defeat the method, and Vizard Agent will say so before wasting a render. Flares across a face shift skin tones, and heavy compression makes the colour edges blocky.
Common questions
Why not just patch it? Because it moves and changes shape, and the picture under it is fine. Vizard Agent untints instead.
What if something else is that colour? Then the mask catches it too. Vizard Agent checks for that before correcting.
What if the flare is white? Much harder. Vizard Agent has no colour to target, and often no detail underneath.
