EcoTubeHQ automatically plays highest quality / lowest bitrate YouTube videos, i.e. av1 codec videos are output by default, if av1 isn't available then vp9 is utilized, and if vp9 isn't available then h.264 is output.

Features:

• EcoTubeHQ offers two video upscaling methods: 'Quality' and 'Powersave'. 'Quality' video output @720p is comparable to 1080p YouTube video quality.
• EcoTubeHQ can minimize CPU usage by utilizing Vulkan GPU Compute Acceleration during video output.
• EcoTubeHQ automatically opens low resolution YouTube videos [144p / 240p] in a small window. This can be used as a low bitrate miniplayer.
• EcoTubeHQ offers debanding to minimize video artifacts.
• EcoTubeHQ restricts 720p videos to 30fps.
• EcoTubeHQ offers drag and drop video playlists.
• EcoTubeHQ can play local video files with AMD FidelityFX Super Resolution.
• EcoTubeHQ offers two Opus audio bitrates for av1 and vp9 YouTube videos - 70kbps and 160kbps.
