What is a DASH container?
A while back, YouTube started to use the DASH technology (Dynamic Adaptive Streaming over HTTP) for SD 480p, HD 1080p, UHD 2K, and 4K videos. DASH technology is called adaptive bitrate streaming, where a multimedia file is divided into one or more segments and delivered to a client using HTTP.
