Corner-mount a talking head after both plates are keepers
create_ugc_video_overlay puts a required-position PiP on a single base video. Overlaying two maybes, or PiP before picture lock, composites a reaction to a take you will replace.
create_ugc_video_overlay is the classic reaction layout: one base (gameplay, screen, product), one talking-head or reaction clip in a defined corner. position is required. No free-form pixels. remove_black_background only strips black on the overlay. A different overlay backdrop needs a real key first. compose_video_with_overlay is the fuller mixed-media cousin. This tool is the direct PiP. Direct is not early.
Add picture-in-picture to a video is the job. Standard composite billing. estimate_cost on a long base. The UGC generator is how many talking overlays are born.
Two files, two locks
The base has to be the base. The face has to be the face. A new gameplay take and a new reaction take do not inherit the old corner composite. You will PiP again. Doing it first is how you fall in love with a layout of two files you will delete.
Key the overlay on a locked talking clip if it needs a matte, then corner-mount onto a locked base. Keying a maybe, then PiP onto a maybe, is the background-removal leak plus this one.
If you needed several bases plus an overlay, this is the wrong tool. Compose, later, with keepers.
Order
- Sign the base. Sign the overlay performance.
- Key the overlay only if the backdrop demands it and only if that overlay is the overlay.
- PiP with a corner you meant.
- Caption the composite if the face is speaking. Captions on the overlay file alone will sit in the wrong rectangle.
Do not treat PiP as a way to hide a weak base with a funny face. The face is small. The base is the shot.
FAQ
Can I move the PiP by a few pixels?
No. Corners. If the product is in that corner, pick another corner, on a keeper whose product is not in all four.
Should I resize the base to 9:16 before PiP?
Reframe the destination first so the corner is the corner the phone will show. PiP on 16:9 then crop to 9:16 is how the head gets clipped. Crop the keeper base, then mount.
Is a black-matte overlay enough to skip keying?
If it is truly black, remove_black_background on this tool may suffice. If it is a room, key properly, later, on the signed overlay.
Why is this later than generating UGC?
Because UGC generation is sampling. PiP is a composite of two samples that have graduated.
