This API allows a transition between two video sequences with the choice of the FPS. The transition takes place over 1 second: the total time of the video obtained is therefore the sum of the two videos minus 1 second.to choose: - the transition mode (circle, horizontal slide, vertical slide,...)- the FPS value: 1 for 8 FPS, 2 for 16 FPS, 3 for 24 FPS, 4 for 30 FPS, 5 for 60 FPS.Be careful with videos that are loaded too long or have too many frames!Duration: generally less than 3 minutes (example tested: 2 minutes and 10 seconds to link two videos, one of which is 25 s and the other 30 s, each in 30 FPS, keeping the 30 FPS for the output video of 54 s)
