How to cut a bad moment out of a clip and still fill the same amount of time
Tell Vizard Agent roughly where the fault is and that the shot has to stay the same length. It examines the frames around that moment to find where the fault actually begins, trims the clip there, and loops the clean portion back on itself with a crossfade so the slot stays full.
What do you type into Vizard Agent?
Describe the fault in ordinary words. You don't need the frame number: finding it is part of the job, and a description like "a weird step" is enough to tell Vizard Agent what kind of wrongness it's looking for. Do say the length is fixed, or shortening the shot is the fix it will reach for first.
Prompt
What does Vizard Agent actually do?
Most of the work is locating the fault, because a fault located approximately gets trimmed approximately and shows up again two frames later. A strip of consecutive frames shows which one is the first bad frame, and that's the frame Vizard Agent cuts on. In the session behind this article it:
- Inspected a clip of a walking figure that glitched two thirds of the way through, pulling the frame before the fault, the faulty frame and two after.
- Built a motion strip of the region, probed the durations and confirmed the last clean frame before the fault began.
- Grabbed the opening frame to plan the loop blend, since a loop joins the end of the clip to its own beginning.
- Trimmed at the fault, crossfade-looped the clean take, rebuilt the background around the trimmed looping clip and composited the type and audio back onto the fixed cut.
- Extracted frames at each loop blend and reviewed the motion across the whole ending, blend by blend.
When does this not work well?
A loop needs something loopable. Motion that goes somewhere, like a camera push, a subject crossing frame or a reveal, cannot repeat without obviously repeating, and a clip whose fault is at the start has nothing clean to loop from. Speech or music in the clip loops audibly, and a blend across a lighting change shows.
Common questions
How exact does my timing need to be? Not very. Vizard Agent finds the frame from your estimate.
Will the loop be visible? Not if the motion suits it. Vizard Agent tells you when it will not work.
What if the audio loops too? Say so. Vizard Agent can keep the audio running and loop the picture only.
