Happy Birthday §ôµÏG®ïñD.
so what did you do and get on your birthday? how are you doing btw?
on this song, i find the musical arrangement, instrumentation, singing melody, costumes the singer and dancers wear, choreography, hair styles, stage design, and lighting are pretty much perfect. the singer has a good to very good quality of voice too.
the video was probably in 480i native resolution but it was upscaled to 4k to use higher bitrate of 4k lossy compression which should reduce compression of 480i on youtube which is cool. the only strange thing about this video is that the aspect ratio isn't correct. maybe because 480i has a resolution of 720 x 480i which is a 3:2 pixel perfect square shape aspect ratio but most 720 x 480i sources squeeze the pixels in horizontally to correct the aspect ratio from 3:2 to 4:3. which means the pixels will be rectangular with the longer length in the vertical side of the pixels. maybe this video didn't squeeze the 3:2 pixel perfect square to 4:3 aspect ratio during the editing where it was upscaled to 4k.
so that means the image will be a bit stretch out making the picture looks wider than the original size.
