The author says they don't believe that a lighter version has been shown to reduce engagement. I, on the other hand, fully believe that. The recommended lite-youtube-embed project page has a demo of both lite and regular players [0], and the lite version takes noticeably longer to start playing the video. Every additional millisecond of load time will reduce engagement, and here the difference is more on the order of hundreds of milliseconds or more.

I don't think the point of this is to replace highly critical videos. It's to replace videos like installation instructions which may only be needed by 10% of your users. Not only that but 250ms is the average reaction time of a human, you don't notice an extra 5 milliseconds. If a video is required on your website for engagement you probably shouldn't be hosting it on YouTube anyways.

  >Not only that but 250ms is the average reaction time of a human, you don't notice an extra 5 milliseconds. If this is true, then why are online first person shooters noticeably worse when playing with a 250ms ping connection compared to a 5ms ping? 250ms ping is basically unplayable. If I recall correctly. I stopped playing video games many years ago, because my college’s internet connection didn’t offer low enough latency to be able to play.
  - thfuran 2y ago
    The difference between 5 ms and 250 ms is a lot more than 5 ms, so there's no contradiction.
    - lotsofpulp 2y ago
      Oops, yes I misinterpreted that. I was thinking how can 250ms be the average reaction time when it’s too slow of latency to play a video game, wouldn’t average reaction time have to be lower since people do notice lag at 250ms pings?
      - Filligree 2y ago
        Humans can notice and characterise much smaller intervals, down to somewhere around five milliseconds. We still aren’t capable of reacting faster than about 250. However, if you have latency of 250ms then your total reaction time isn’t 250, it’s 500.
        LocalH 2y ago
        With aids, we can perceive and notice even smaller intervals. I play a lot of Fortnite Festival, which is the Rock Band-style mode added near the end of the year. This game, unlike any previous game in the genre, has "perfect" judgements for note hits. The window for a perfect judgement is something around 20 or 30ms. The game also gives you an average offset from "dead on" for each song, measured in milliseconds. Since the perfect judgement is immediate feedback, it enables players to perceive when they are just a few milliseconds off and correct for it. I regularly get average offset results of +/- 3ms or better, including plenty of 0ms average offsets (this is of course averaged across all notes in a song, which I am playing on a plastic guitar on Expert difficulty). I'm nowhere close to the best player either, there's one player who recently got one of the most impressive full combos of the Metallica song One that could ever be done - they hit all notes without mistake, they got 100% perfect judgements, and they got the #1 leaderboard score, meaning that not only did they hit all notes within the 20-30ms "perfect" window, but they also "squeezed" overdrive activations within that window to activate and hit the first note as late as possible, and hit the first note after that overdrive activation would end as early as possible to still get it under the extra 2x score multiplier that overdrive brings. The game genre also overcomes the relatively huge (in the context) human reaction time by providing you gems to read before the strikeline (or "now bar"), so that you can basically internally correct for your reaction time, similar to how people reading sheet music can perform in lockstep rhythm when everyone is skilled. It's amazing what different forms of augmentation can do to help paper over the inherent shortcomings in our senses.

  > Not only that but 250ms is the average reaction time of a human, you don't notice an extra 5 milliseconds. Please stop repeating this sort of thing as a simple fact. Time and latency are difficult things to reason about and simple explanations sound particularly convincing when one lacks an intuitive understanding of the subject. Perceived latency is not the same thing as "reaction time". What reaction was measured? How? From what stimulus? Your reaction time number does not support your claim that humans can't notice a 5ms difference in lag. In any case, you are misunderstanding and misrepresenting the comment you replied to. When you are talking about an organisation like Youtube (size, money, mercenary, malicious, etc.) and discussing metrics like this, individual milliseconds is not an unreasonable unit to use. Consider the volume of the data. Nobody is saying that if something takes 5ms longer to load that no single human being will be capable of waiting for it anymore. Further, your 250ms is perfectly in the range of the parent comment's order of magnitude of hundreds of milliseconds.
nnf 2y ago
I would much rather wait a few hundred milliseconds for a video to start during the few times I decide to watch an embedded video than to wait for the full video player to load every single time I visit a page with an embedded video that I'm never going to watch. Similarly, I would much rather have every stoplight I approach be green for me rather than having every light be red but for not very long.

Does the potential lesser engagement with videos matter in the face of those videos causing a delay in loading the page that displays them? You'd need to check per-video engagement drop against people not bothering to engage with the site in the first place.

  This is an example of the tragedy of the commons: the watch time effect is tracked by YouTube, which maximises for it, but the drop off of visitors to the site is something YouTube doesn't "care" about (doesn't track it directly, doesn't optimize for it, etc.).

I'm not seeing such a difference, but it is there. I'd be surprised if it was as high as 100ms. Obviously different computer environments[0] will have an impact here. I would be much less likely to notice it as "slow" if it didn't show me a spinny-spin. It's advertising that it's slow!

I suspect you’re right, but on the other hand, I think it’s useful to think critically about whether starting the video faster is worth it if it makes the web page that it’s embedded in load slower. The “every millisecond counts” argument applies to the web page too. If the user bounces off the web page, they won’t get to the video anyway. Also, maybe it’s fine if people don’t want to play the video? Personally, I appreciate it when a web page includes a summary, so that I can avoid watching a video. (I prefer not using YouTube for anything other than listening to music or occasionally watching a movie.) Video can be a useful tool, but consider whose interest it’s in for you to encourage your audience to watch more TV. Is it really serving your users? Even when I do want to watch a video, it’s selective. One thing I find rather frustrating about YouTube’s redesign (on desktop) is that it devotes so much screen real estate to promoting videos other than the one you’re actually there to watch. I’d prefer fewer distractions.

- marcosdumay 2y ago
  It used to be that if your network was bad, you could just play the video once without watching, and then you could play it again and watch it without it locking. Nowadays, if your network is bad, you can just forget it. Every single media site seem to have migrated into this format at around the same time. It's obviously to stop downloaders, what it evidently didn't, but it will never change back.
  - ric2b 2y ago
    Is it to stop downloaders? I doubt it since they work just fine, it's probably just a way to reduce resource usage on more constrained platforms like low end mobile phones or smart tvs. There is probably a lot of code sharing among all platforms such that companies don't want to support two different buffering flows.

> Every additional millisecond of load time will reduce engagement LOL! What's engagement?! Half the embeds I see don't work because the content is censored or rotted. For content that plays, the rush for my attention includes an overwhelming dynamic of at least three parties with vested commercial interested in the occupation of my mind cramming unrequested and unwanted advertorial content into my nervous system. Blocking unrequested content and keeping a healthy distance from tracking adds many seconds of delay to access of requested content, and the requested content typically has a cognitive half-life of a few seconds to minutes. And the requested content itself typically contains order 10,000x milliseconds of insipid attention mgmt jingles and branding setup. Then to finish it off. Even the most high-minded productions waste minutes of egress begging for "likes, subscribe, comments," reading off lists of sponsors with silly handles, admonishments for upsells, and cappers to "hit the bell, it's so, so, important", immediately following which the player bot resets to cramming a new unrelated vid into my sockets.

Presumably, the person clicking the video has a desire to watch it and thus can stand that the video takes an extra 300ms to load.

So from those metrics, it's pretty easy to tell those two divisions apart.

I thought we were past the era of counting in milliseconds for load time now that half the web insists on using cloudflare security checks
