Jack . . .


. . . of all trades. . .


Master of very few.

One of the most difficult things about being an independent artist, or maybe I should say LOTS of the most difficult things about being an independent artist, are those THINGS other than making the music.

I mean now we've got (and have had) YouTube which, don't get me wrong, is a wonderful thing but . . . . . .

"Recommended bitrates, codecs, and resolutions, and more
Container: .mp4

    No Edit Lists (or you may lose AV sync)
    moov atom at the front of the file (Fast Start)

Audio Codec: AAC-LC

    Channels: Stereo or Stereo + 5.1
    Sample rate 96khz or 48 khz

Video Codec: H.264

    Progressive scan (no interlacing)
    High Profile
    2 consecutive B frames
    Closed GOP. GOP of half the frame rate.
    CABAC
    Variable bitrate. No bitrate limit required, though we offer recommended bit rates below for reference
    Color Space: 4.2.0

Frame rates
Frame rates should match the source material. For example, content shot in 24fps should be encoded and uploaded at 24fps. Content recorded at 30fps should be uploaded at 30fps. Content shot in 720p60, should be uploaded at 720p60. Content at 1080i 60, should be deinterlaced, going from 60 interlaced fields per second to 30 progressive frames per second before uploading.

Resolutions

YouTube uses 16:9 aspect ratio players. If you are uploading a non-16:9 file, it will be processed and displayed correctly as well, with pillar boxes (black bars on the left and right) or letter boxes (black bars at the top and bottom) provided by the player. If you want to fit the player perfectly, encode at these resolutions:

    2160p: 3840x2160
    1440p: 2560x1440
    1080p: 1920x1080
    720p: 1280x720
    480p: 854x480
    360p: 640x360
    240p: 426x240

The YouTube player automatically adds black bars so that videos are displayed correctly without cropping or stretching, no matter the size of the video or the player.

For example, the player will automatically add pillarboxing to 4:3 videos in the new 16:9 widescreen player size. If the player is re-sized (i.e. when embedded on another website), the same process takes place so that 16:9 videos are letterboxed when the player is sized to 4:3. Similarly, anamorphic videos will be automatically letterboxed when shown in either 16:9 or 4:3 sized players. The player can only do this if the native aspect ratio of the video is maintained.

You can adjust the fit of your video in our player after uploading your video by using formatting tags.

If letterboxing is added to a video before it is uploaded (i.e. in the case of creating a 4:3 video from a 16:9 master), the widescreen player will add pillarbox bars too, resulting in black bars all around the video (windowboxing) and a bad viewing experience (see the diagram below). . .
