I’ve been wondering—does the actual quality of the picture and sound change depending on which tool you use? For example, if I grab the exact same video with one downloader, I might end up with a file that's 445MB, a bitrate of 562kbps, and audio at 254kbps. But if I use a different downloader for that same video, I get a measly 264MB, a bitrate of 281kbps, and audio at just 126kbps, even though both are 640x480 pixels in MP4 format with AAC 2-channel audio.
