About Adaptive Streaming Videos (DASH)
In October 2013, YT stopped providing 480p and 1080p videos complete with audio. See: http://googlesystem.blogspot.com/2013/10/youtube-drops-support-for-1080p-streams.html
480p and 1080p are now video-only. There are separate audio streams to download and package together with these video streams to make MP4 files. CYS will do all this for you automatically in a process called “muxing”, with a single click, but you need to have the latest version of FFmpeg installed on your system and set up in CYS Options. Details are posted here: http://www.cys-audiovideodownloader.com/Converter.html
DASH videos can be identified in the list by the "dash" symbol on the left side column. Also, DASH videos contain three digits in the format number, from 133 and up, for example: “fmt 133”.
Without FFmpeg installed:
-DASH video formats appear in the CYS list as MP4V files and contain NO AUDIO.
With FFmpeg installed:
-DASH video formats appear in the CYS list as MP4 files. CYS will download the video and audio files and merge them automatically. DO NOT try to play the separate files while they are downloading. Wait until the two files merge and then you can play the resulting MP4 file.
Depending on the video, the following DASH formats are available for download with CYS v5.4.4 (with FFmpeg installed):
Fmt 138 MP4 Original 2304p
Fmt 264 MP4 Ultra HD 1440p
Fmt 137 MP4 Full HD 1080p
Fmt 136 MP4 HD 720p
Fmt 135 MP4 High Quality 480p
Fmt 134 MP4 SD 360p
Fmt 133 MP4 Low Quality 240p
Fmt 160 MP4 Low Quality 144p
DASH WebM (VP9) formats where available:

Fmt 271 WebM Ultra-HD 1440p
