Did anyone else notice that when HBO adapted that snow intro to wide screen, it looks like they just cloned an existing chunk of snow onto the left and right borders.
Maybe it's just an illusion. But I swear I can see the seams where the widescreen pixels start
- fshbbdssbbgdd 4y agoThat’s one way to make it compress better.
- renonce 4y agoAre modern digital video formats good at compressing chunks of pixels far apart in the video screen? It's not like zlib where identifying duplicated chunks is part of compression.
- Tuna-Fish 4y agoThe formats absolutely have the capability, but it's an another question if the encoder is capable of noticing the duplication. (Modern video formats are not deterministic in that the same source always encodes to the same output for the same format. They are more like programming languages that they provide as set of tools you can use to compress various different kinds of redundancy out, but it's the job of the encoder to find that redundancy. For example, one of the tools typically available is to provide a source image to an off-screen buffer, and then when rendering the screen, occasionally provide offset/length pairs into that buffer instead of pixels. This could be used for efficiently encoding the duplicated noise.)
