You can right click any video on YT and click "stats for nerds" to show bitrate and codec, just click around on different videos and you'll notice a difference. What I have observed personally is: If you upload >1080p, youtube encodes that and also the 1080p version with vp9.
- Encoding Cost and Bandwidth Savings
- AV1 For Multiple Million View Counts
- VP9 For Multiple Thousand View Counts
- H.264 For The Great Unwashed
- The Bottom Line
In terms of cost/quality tradeoffs, the last time I looked, AV1 (libaom-AV1) took about 18 times longer to encode than H.264 (x264), which translates directly into 18 times the encoding cost if you’re running your own encoding farm, which YouTube does. In contrast, VP9 (libvpx-VP9) took only twice as long as H.264. At best, I found that VP9 saved a...
Let’s start at the top. Clicking Explore then Music, I checked the top ten “hottest videos of the week” in the music section. Most of these videos were newly released, yet many had over 5 million views. Eight of the ten videos were encoded using the AV1 codec; the rest were VP9. Interestingly, YouTube whiffed on the fabulous Olivia Rodrigo video(it...
Next, I checked the top 10 news videos, all with much lower view count, and with much shorter legs than other categories that I checked (news being topical and all that). Though the view count ranged from 4,582 to 673,454, YouTube encoded all videos using the VP9 codec. Next, I checked gamingvideos, which enjoy greater view counts than news and pre...
Finally, I looked at the videos that I produced, all with pathetic view counts (note to self: fire marketing director). As you can see below, it was all H.264. I checked Streaming Media’sYouTube videos which enjoyed counts into the low several hundred and they were all H.264 as well.
The bottom line appears to be: 1. View counts below a few thousand – use H.264. 2. View counts reaching into the mid-five figures, say over 3,000 or so – consider VP9. Again, since Google’s use of VP9 may be triggered by the Argos VCU, you should do your own testing with your encoding setup to confirm this result. 3. Don’t consider AV1 until view c...
Aug 18, 2023 · YouTube uses different codecs and bitrates for different resolutions and devices. Depending on the quality of the originally uploaded video and when the video was uploaded, YouTube compressed and converted both video and audio to allow for faster streaming to viewers.
That's because youtube uses different codecs for live stream transcoding. If you send 1080p it will transcode with AVC which is not so good for fast moving scenes like FPS games. If you send 1440p then it will use VP9 (same as twitch uses). and this one is already quite good for quality streams with fast moving scenes.
YouTube uses 4 container formats and 4 different codecs. It depends on the popularity of the video what codecs are used for your video (see below why). Generally, every of your uploaded videos will be encoded in h.264 and will be muxed into an .flv and .mp4 container.
