Recently, I was invited to review Allavsoft and I used it a lot to download YouTube videos and playlists and it was working great. However, there is no audio in some of the videos Allavsoft downloaded. When I use Mediainfo to check the videos’ basic information, I found there is no audio stream in the video and the video codec is AV1.
I did some further searches on Google about AV1 and I will share my experience of how I download YouTube AV1 videos with you on PC and Mac.
According to Wikipedia, AV1, full named as AOMedia Video 1, is specially designed for better video streaming over the internet and it is free, open, and royalty-free video coding format, aiming to replace VP9. Google began testing this kind of video in Chrome 70 and later versions. And we get more and more AV1 (av01) streams from YouTube now.
And, you can check if the video codec on YouTube is AV1(avo1) by right-clicking on the video and select “Stats for nerds” :

I didn’t test all YouTube video downloaders, but here’s what I found when I was downloading YouTube AV1 videos. The Allavsoft that I reviewed a couple of days ago successfully download the AV1 video stream from YouTube, there is no audio. No matter how many times I tried re-downloading, the result is always the same.
Then, I tried another awesome YouTube downloader, VideoProc. As I used it to download 60FPS YouTube videos. However, it failed to download YouTube AV1 video at the very end.

Why the Video Codec Doesn’t Show As AV1?
In one of my previous posts, you see that I recommended an online YouTube downloader to download YouTube, Dailymotion, Vimeo, and many other online videos right within your browser. However, as you can see, there’s no audio track in higher resolution videos like 1080P, 4K and 8K. But, why can we hear audio after we download the AV1 video? The general solution for those YouTube downloaders to download high-resolution YouTube videos with audio is to download the video and audio separately, and then join the video and audio. During the join, they convert the AV1 codec to more common codec AVC.
