Requirements for High Quality / HD

(12 posts)

    What settings must your video have to be HD or high quality on YouTube? Your trusty hotfornerds investigates. These are my findings: If your video meets the specs for "watch in HD," you will get that link. If it doesn't, but meets the "watch in high quality" specs, it will get that link instead. If it doesn't meet any of those, it will be plain old normal quality.

    For "watch in HD," the video must be at least 1280x720 (in width and height), and minimally have a video bitrate of (about) 1000kbps or higher (but you probably want it at 2-4000 at such a high resolution), and a framerate of at least 23.976.

    For "watch in high quality," the video must be at least 480x360 (in width and height), have a video bitrate of (about) 1000kbps or higher, and a framerate of at least 23.976.

    If you're not sure how to get that information on your video, see my blog entry on How the Heck Do I Find the Bitrate of My Video?.

    My audio is skipping. My last two videos (Gorby and Shabby) skipped.. Gorby was REALLY bad at a minute on: http://www.youtube.com/watch?v=Jq07qaox-L0&fmt=22

    I encoded at AAC 256... should I do it at 192?

    First off, I'm sorry to hear about Gorby!

    I'm downloading it now and will analyze it soon, but have you done anything different than with your other HD videos? If not, it could be a glitch on their end. Wild guess; I know VBR audio can sometimes be a problem. In the mean time, you could try leaving it uncompressed if there's an option for that (or perhaps lossless compression if it lets you). The increased file size isn't a huge deal; it amounts to around 1500kbps and you'll get better quality because then it's only compressed once by YT, skipping extra compression by you.

    The normal quality version's MP3 plays fine with no problems. The AAC from the HD version definitely has problems. Conclusion: it's a glitch on YT's end (and not the first audio problem either). The question is: did you do anything differently than last time, or did this glitch appear from nowhere?

    And be sure to describe the problem in the community forum for Bug Reports and Issues. YT has taken notice in the past.

    @Marina,
    the short answer; yes try MP3 at 192 kb/s audio

    Possible glitch:
    When I watched the Gorby video on the HFW site (embedded video),
    the video file in my cache was totally different than the other videos.

    Here is a comparison:
    ---------------------------------------------------------------------
    "Gorby" video (embedded HFW) shows:
    __Video: Flash Video1 320x180 (Video)
    __Audio: MPEG Audio Layer 3 22050Hz mono 64Kbps (Audio)

    The previous video, "Subcribe" (embedded HFW) shows:
    __Video: MPEG4 Video (H264) 480x270 ((C) 2007 Google Inc. v08.13.2007.)
    __Audio: AAC 44100Hz stereo 137Kbps ((C) 2007 Google Inc. v08.13.2007.)

    As you can see, the "Gorby" video specs are totally weird. (file in my cache)

    Either you tweaked something in the embedded code, or the video
    upload YT encoder got confused as can happen from time to time.

    Those are the usual specs for a widescreen video in normal quality (320x180 flash) and a "watch in high quality" version (480x270 flash).

    The 320x180 of Gorby plays fine. However, the "watch in HD" (&fmt=22) version (1280x720 AVC/AAC) is the one with the problem. I downloaded it to confirm; and that AAC definitely has issues. I'm pretty sure this is a problem with the file on YT's server, and not an embedding issue.

    One of my viewers had the same issue, and we successfully resolved it:

    I changed the Audio Settings from AAC to Apple Lossless and the sound is incredible now. Wither this problem was peculiar to my screen capture software (Screenflow for mac) or not I'm not sure. Anyways all is sweet atm. Thanks!!

    So it looks like lossless is the way to go - and you'll get better audio too.

    Cool NerdWithNoLife..I'm going to try the lossless...

    Compressor on the Mac doesn't allow mp3 (recommended by YouTube) with Video... so Lossless.. here I come!!!

    Hi,
    Looked at all YT HD forum posts because my iMac FlatPanel was having a hard time playing even SD. Interesting. Anyway my comment is about YT's practice when it generates FLV. I gave up and only use uncompressed audio. The only exception is .H264 which is m4a or acc. Just my 2-cents worth. I usually send my video to video.google or video.yahoo -- downside is both are not "The YouTube".

    Footnote: the G1 phone plays all HFW video quite well via the youtube app. Must use MPEG Streamclip to convert iTunes downloads or video player app chokes.

    Done for now.

    Things have changed again, so here's an update.

    YT has significantly increased the quality of normal videos, making the "watch in high quality" link less relevant. What I think happens is: YouTube creates a high and low quality video. If after the conversion, the high quality video isn't much different, you get a normal video. If for some reason they are really different, you'll get a link for high quality.

    The beefed up normal quality video is now the same size as the player - 480x360 for 4:3 and 640x360 for widescreen. This is very good, because there used to be a huge difference if you didn't get the video in high quality because it was a much smaller (320x240 or 320x180) video scaled up to the player size. Now you can save all that aggravation. The normal quality videos aren't actually that bad.

    So I recommend focusing on producing better looking higher quality videos, rather than worrying too much about YouTube and its settings. They're starting to handle videos in a much better way.

    The HD videos work same as they used to. If you have a fast computer and fast connection, they are great. If not, they'll be so laggy as to be unwatchable. It will take time for technology to reach the point where HD can be done with ease, especially HD on the internet. "HD on the internet? That's crazy talk," I would have said a couple years ago.

    This is interesting. I had the cable, and that worked great. I then went with the 256 phone line whatcha ma call it, could not watch anything on the computer so had to upgrade. Gotta start with a good connection or no go on jack.
