Color Subsampling, or What is 4:4:4 or 4:2:2??
In the video space, there’s always a lot of talk about these number ratios – 4:4:4, or 4:2:2, or 4:1:1, but what exactly do they mean?

They were wrong, and I’m going to explain why.

אכן, זה נושא די ישן, ובטח כבר כולם יודעים מה אומרים כל המספרים האלו. (מפיקת פוסט אמרה לי לפני כמה זמן שהמצלמה שהיא הולכת לצלם איתה גרין סקרין היא "רק" 4:2:2)
ובכל מקרה, הפוסט למעלה נותן הסבר לא.
יום יבוא ואני אכתוב הסבר משלי, בעברית.
