How to crop the face cam cleanly out of a stream recording
Ask Vizard Agent to measure the face-cam box on a full-resolution frame instead of estimating its coordinates. It extracts a frame, finds the true edges of the webcam panel, tests the crop on a single clip, and only then rebuilds the whole batch, because a crop that is twenty pixels out repeats the same fault in every export.
What do you type into Vizard Agent?
Ask Vizard Agent for a measurement and a test render, in those words. Between them they save the whole batch, because the alternative is discovering that the crop was slightly wrong only after six clips have already been exported, reviewed and sent on.
Prompt
What does Vizard Agent actually do?
Coordinates estimated from a contact sheet are always a little wrong, because the sheet is scaled down, and a little wrong at source resolution becomes a visible band in the output. So Vizard Agent measures on a full-resolution frame and settles the crop on one rendered test clip before it builds the batch. In the session behind this article it:
- Downloaded the stream recording, inspected its layout and built a contact sheet to see the composition.
- Isolated the face-cam area roughly, then extracted one full-resolution frame to measure the box and set the crop from it.
- Built a test clip with the split-screen layout, found a strip of gameplay left in the top panel and tightened the crop to the true border edge. The crop was adjusted three times, each time from a rendered panel.
- Confirmed the top panel was entirely webcam, then rebuilt the whole batch of six vertical clips with the corrected crop.
- Checked the gameplay panel for leftover overlay strips.
- Sampled several moments to verify the webcam was live, since a low-motion webcam looks frozen to an automatic check.
When does this not work well?
A face cam that moves, resizes, or disappears mid-stream cannot be handled by one fixed crop. Overlays that sit on top of the webcam panel are a separate removal job, and a webcam recorded at low resolution will look soft when it is blown up to fill half a vertical frame.
Common questions
Why not just crop by eye? Because preview-scale accuracy becomes a visible band at source resolution, which is why Vizard Agent measures.
Can it follow a moving face cam? Not with one crop. Vizard Agent will tell you when the box moves.
Can I give it the coordinates? Yes, and Vizard Agent will still verify them on a frame.
