• Do they have to slow down HD to get all the data to a non-HD player?

    Playback a court video on Youtube and the cop sounded like he was on
    drugs. Then I noticed everyone else sounded a little sleepy too. I
    checked playback speed and it was set to Custom 0.7, and I could appear
    to change that but it never did change, except for the embedded
    adverstisement https://youtu.be/M4Pi9O5myWM "Audit the Court" which is
    a series and I've watched 1 or 2 others from that series without
    noticing anything strange. Badge on settings that says HD. I don't
    remember others being HD. Do they have to slow down HD to get all the
    data to play in a non-HD player? Is my 4 yo. PC a non-HD player?

    Is this a common thing? Is there a reason behind it?

    Do you have any significant bandwidth limitations ?

    Right click the playing pane, and bring up the Nerd Stats.

    The video is VP9 and is incoming at 640x360 resolution.
    The connection speed has helped provided 53 seconds of pre-buffer.

    Using YT-DLP, you can list the available formats and
    download the "best format" without selecting anything.
    It might say in the YT-DLP listing of formats, whether
    any actual full HD 1920x1080 content is available.

    The "248" and "251", you should see those in the list of formats
    available as possible streams to play for that content. When
    the "Best" format is played by default, a video stream and
    an audio stream are downloaded, and FFMPEG stitches them
    together to make an output video file.

    I think it is selecting a low-res VP9 and upscaling it,
    for my screen presentation.

    When a player can not cope with the video speed, like having too many
    frames per second of too high resolution, what it does is skip frames.
    Maybe there are players that instead play slower but display all frames.

    Here, the automatic resolution I get is 480p, not HD.

    Changing the "pace" of playback, is not triggered by bandwidth.
    A video player could adjust the resolution selection of
    a stream, if the pre-buffer period measures poor performance.

    Usually, playback speed is a setting somewhere, but in Youtube
    I don't see a control for that. Sometimes the issue is a
    handling issue with the CODEC. Maybe doing the wrong thing
    with an audio sampling rate. Maybe the audio hardware
    is reporting incorrect metadata. But if that were the
    case, you might also lose lip-sync.

    Right-clicking the pane of the video while it is playing,
    and accessing the Nerd stats, should give some info so
    you can identify which exact streams are involved.
    Using YT-DLP, you can capture the same streams and
    play the video in VLC to see if the player there
    does a better job of it.

    I see Playback Speed under Settings on any YT video.
