Topic: Вопрос по уровням
let's take a 1920*1080 video as example
top (higher) level (#1) for the "hierarchical search" is the frame itself - 1920*1080
next one #2 - the frame reduced by 2 in each dimension - 960*540
#3 - 480*270
#4 - 240*135
bottom (lower) level #5 - 120*67top level = "finest" level
all other bottom levels are "coarse" levelsthe search parameters are _different_ for coarse and top levels
levels from #5 to #2 - more exhaustive search, level #1 - simplified searchwith this "width of coarse level" option we can move this "line" down: levels 5 to 3 - exhaustive, levels 2 to 1 - simplified
and this is more important for 4K video
нашел тут в английской ветке, назрел вопрос, можно ли эмулировать сетку 32 пикс с помощью сетки 8 пикс и отключением финального и пары грубых уровней?
