How to stop your face looking wider and narrower from one shot to the next
Tell Vizard Agent where your face seems to change shape. It first proves the picture is not stretched, then compares source and export at the same moments. When the cause is a wide phone lens at different distances, made worse by slow digital zooms, it takes the zooms out and hides the moments the camera gets very close.
What do you type into Vizard Agent?
Describe the symptom in your own words. "My face looks slimmer and then fatter" sounds like a scaling bug, and the quick fix for that is the wrong one if nothing is actually stretched. Letting Vizard Agent find the cause matters, because the cause decides the fix.
Don't change my appearance or voice. My face is slimming and fattening in a weird way. Fix that.
What does Vizard Agent actually do?
It separates three causes that look alike: a wrong aspect ratio, a zoom, and lens perspective. A phone's wide lens makes a face wider in the middle the closer it gets, so cutting between a full-body shot and a close one, or zooming in slowly, changes the face's shape. In the session behind this article it:
- Ruled out stretching: both sources and the export had square pixels and the same scale in both directions.
- Built a board of matching source and export frames at seven moments, then had the change analysed specifically for warping versus camera perspective.
- Found two moments that stood out: a cut from a full-body shot to a close three-quarter view, and the camera's own walk-in to a close-up.
- Saw that slow digital push-ins on every segment were adding to the effect, and set the zoom back to none everywhere.
- Moved one segment to the other camera, cut the walk-in short and covered the camera's approach with a cutaway, then wrote the no-zoom rule into the saved template.
When does this not work well?
When the close-up is the only take of an important line. Perspective from a phone held close is baked into the picture, and no edit can undo it, so the choices are a cutaway, the other camera angle, or living with it. Next time, film from a little further back.
Common questions
Is my video stretched? Vizard Agent checks the pixel shape and scale first.
Why does my face change between shots? A wide lens at different distances. Vizard Agent avoids the closest shots.
Do zooms make it worse? Yes, on close phone shots. Vizard Agent can remove them.
