 <\/p>\n

When we watch a video on the platform, we can usually appreciate that, despite finding videos in 1080p resolution, the compression applied by the platform is too aggressive. This causes the final quality of the video we are watching to differ greatly from that of the original file. The codec that YouTube uses is H.264 \/ MPEG-4 AVC, using various profiles or \u201clevels\u201d that specify the maximum resolution, frames per second and maximum bitrate of each quality.<\/p>\n

\"\"<\/a><\/p>\n

We have analyzed a few videos, and we have taken a fairly representative one that is available on both Vimeo and YouTube to see how both platforms compress the videos. In addition, we have seen the maximum and minimum bitrate that each video can have according to the YouTube Help page for each resolution. The audio, as we discussed in summer, reaches 128 Kbps, leaving 320 Kbps only for YouTube Red users.<\/p>\n

What sound quality (bitrate) do YouTube videos have?<\/p>\n

The bitrate for 1080p videos is too low: 4K is the way to go
\nThe bitrates that YouTube says it assigns to each video are the following, with the profile level in parentheses:<\/p>\n

4K \/ 2160p
\n60 fps: Between 20,000 and 51,000 Kbps (L5.2)
\n30 fps: Between 13,000 and 34,000 Kbps (L5.1)
\n1440p
\n60 fps: Between 9,000 and 18,000 Kbps (L5.1)
\n30 fps: Between 6,000 and 13,000 Kbps (L5.0)
\n1080p
\n60 fps: Between 4,500 and 9,000 Kbps (L4.2)
\n30 fps: Between 3,000 and 6,000 Kbps (L4.1)
\n720p
\n60 fps: Between 2,250 and 6,000 Kbps.
\n30 fps: Between 1,500 and 4,000 Kbps.
\n480p: Between 500 and 2,000 Kbps.
\n360p: Between 400 and 1,000 Kbps.
\n240p: Between 300 and 700 Kbps.<\/p>\n

\"\"<\/a><\/p>\n

In our tests, the bitrates we obtained for the previous video were the following:<\/p>\n

4K at 30 fps
\nVimeo: 19.4 Mbps (file size: 943 MB) (capture)
\nYouTube: 17 Mbps (file size: 821 MB) (capture)
\n1080p at 30 fps
\nVimeo: 4.31 Mbps (file size: 219 MB) (capture)
\nYouTube: 3.2 Mbps (file size: 160 MB) (capture)
\nvimeo vs youtube compression<\/p>\n

As we see, Vimeo files occupy more not only because of the lower compression of the videos, whose quality is superior to the naked eye, but that Vimeo’s sound quality doubles that of YouTube, since it reaches 256 Kbps by 128 Kbps from YouTube. So that you can see the difference in image quality, you can open the same New Zealand Ascending video on YouTube and Vimeo, and we have also left four captures at the same moment of each video so you can save them and see comfortably the video difference.<\/p>\n","protected":false},"excerpt":{"rendered":"
