Adjacent
Adjacent creates a sliding sequence. Each image is reused with the next image.
1+2
2+3
3+4
4+5
5+6
Frame Pair to Video uses two source images for each video: a start frame and an end frame. The pair logic controls how uploaded images are grouped into those start/end pairs.
Adjacent creates a sliding sequence. Each image is reused with the next image.
Grouped creates separate pairs. Each image is used once.
Use Adjacent when your images are a continuous sequence and you want each step animated into the next.
Use Grouped when every two images are a separate start/end pair.
In Grouped mode, an odd final image has no partner, so it is ignored. For example, 5 uploaded images produce 1+2 and 3+4; image 5 is left unused.
