Maybe they're not telling about some of the detail (and they've clearly given it plenty of thought!) but it seems wasteful to fully process all frames when in several cases many of them will never be selected. eg if it fails due to poor Visual Metadata (such as strong motion blur or very low brightness) you'd want to abandon all frames like that before running the other processing.
- mkl 8y agoThey probably do, for efficiency. You have to process a frame to some extent to detect motion blur or darkness (how else could you possibly know?), but that doesn't mean you can't abort the processing as soon as you detect the frame is totally unsuitable. I expect whole groups of frames may be able to be discarded more-or-less together, e.g. a dark key frame followed by frames with minimal difference, or where the video encoding's motion estimation says there's a lot moving.
