Or, also in Chrome, the WebCodecs team not having talked to the Media Team, seemingly (?) before starting work on what kind of buffer gets returned to the user, and what the semnatics of its color are. Which Chrome then assumes is 709 based off the res. Or in Chrome, the MediaRecorder API will create HD H.264 streams that are untagged, and are 601. You can see this, for example in Firefox's image pipeline which seems to assume everything is 601 (because JPEG), and this means 709 AVIFs won't render correctly (and are thus off by default currently). It's been my experience that part of the reason browsers get stuff wrong even when it's clear what to do, is that entirely different teams work on parts of the browser that all need a poper color pipeline, and while one team will learn and do it correctly, the new team working on the diffrent part has to go through the same process again. Honestly I would rather issue warnings in these cases rather than silently guess. Fwiw Firefox generally does follow Chrome in inferring unmarked bt601/709 based on size. Unfortunately, if you don't mark the videos, that's on you though. There's no good reason for any 601- or 709-marked content to display incorrectly in the year 2021. I hope we can move that needle back towards "implement the specs". There are definitely cases where it's clear what we (as browsers) are supposed to do, but some implementations have chosen to err on the side of user preference rather than correctness. both Firefox and Chrome have issues with full-range videos displaying incorrectly, just with different videos), and also with various implementations deviating from standards to "do the right thing" (though this is also a central dilemma of hdr display/tone-mapping). we know what it should display, but browsers get it wrong still) There are both outstanding issues with browsers being accidentally wrong/incomplete (e.g. I would say that much of it is actually solved in theory, just not in practice. Your browser and my browser see different colors (SF Video 2020, by the author of this post). This is a small sample size, but these are all talks just from a local SF Video meetup and the Demuxed conference, and the speakers work at YouTube, Vimeo, Mux, and a fruit company.Įarly Experiments in Color Vision and Their Applications to Modern Color Theory (SF Video 2017) - Ī Jaunt Through Color Technology in Video (Demuxed 2017). Color theory is one of those areas that people working directly with it see it as a completely unsolved problem, and everyone else largely takes it for granted. Probably unsurprisingly, the (honestly absurd world of) color is a pretty consistent topic among video engineers.
