(*) For some format-resolution combinations, YouTube stores audio and video streams separately, therefore, to download video with sound, they must be “glued” (muxing). For small files (up to 200 MB), this resource-intensive operation is done by extension “on the fly” (right in the browser). For larger files, a user is redirected to our site with UDL Client software to avoid “freezing” in the browser. MP3 file format also isn't supported by YouTube and needs to be converted with a third-party desktop client.
