Remove Black Borders with Aspect Ratio


Login to YouTube video manager and add the following tags:

Tag: yt:crop=16:9
(zooms in on the 16:9 area, removes windowboxing)

Tag: yt:stretch=16:9
(fixes anamorphic content by scaling to 16:9)

Tag: yt:stretch=4:3
(fixes 720x480 content that is the wrong aspect ratio by scaling to 4:3)

Tag: yt:quality=high
(default to a high quality stream, depending on availability)

Result: Notice how black borders are removed and video aspect is altered.
