It's possible that some tasks with videos have no manifest. There are
several reasons for that, including manual playback speed manipulation
attepts. CVAT will generate no manifest for such videos, but the
chapters functionality will try to read the chapters from the manifest
regardless. It's technically possible to ignore bad keyframes, but it
can lead to invalid chapters.
