Where do you see 4k?

[goldensun87]

Hmm, well that's unfortunate. I was hoping it had 4K, because it's in the title, and the Youtube upload has 4K. Apparently, Vevo doesn't have 4K yet, but the Youtube upload proves that the source video was 4K. I'm curious what bitrate Vevo would use for their 4K encodes, if and when they start uploading 4K videos.

[jaimeMF]

Closing since from what you say Vevo doesn't provide 4k video.

[b1he]

Looks like VEVO now actually supports 4k videos. youtube-dl also detects and downloads them correctly too.

@b1he1 Thanks, I had downloaded a more recent 4K upload, which was a Noah Cyrus video, and I did not expect Vevo to upload a 4K copy of an older video. Although, Youtube's 4K videos are actually usually higher bitrate than Vevo's. Which is ironic, because Youtube's 1080p has been getting compressed a lot more ever since they started using DASH video, and as far as I know, 720p and 1080p videos on Youtube get further compressed as time passes. This is why I try to download a 1080p video on Youtube as soon as it is uploaded, because the initial stream file gets replaced by a smaller size file over time.

[b1he]

@goldensun87 Really? Do they re-compress videos to a lower bitrate over time with the same codec? I thought after they started using DASH, their other strategy of saving bandwidth is to make vp9 versions.

[goldensun87]

Yup, they re-compress videos to a lower bitrate over time. I'm still not sure about the VP9 thing though. At first, I thought Youtube replaced H.264 with VP9 for 4K videos, but this is not the case. It seems to me, the H.264 vs VP9 for 4K videos on Youtube, is user-specific. Meaning, perhaps the codec is VP9 when the uploader is uploading, and Youtube is retaining that codec instead of converting the 4K video to H.264. That is just my assessment, I do not know for sure.

[b1he]

@goldensun87 YouTube seems to upload a VP9 version of a video only if it gets popular enough, or if someone uploads a 4K60/8K60 and/or HDR video since YouTube won't encode a H.264 version of these.
