  • how to repeat this ffmpeg effect

    5 septembre 2018, par Vladislav Korobeinikov

    I looking for solution - how to repeat effects :

    1. Zoom on central bottom part at start, with no zoom effect ;
    2. Moving from bottom to top and from left to right ;
    3. Zoom out.

    In this video with ffmpeg filters.

    I read documentation (filters and zoompan filter) from official site, found some information from "ffmpeg basics" written by Frantisek Korbel - but I didn’t find any useful information that solve my problem.

    Also I thought that it could be made with another software.
