2024年7月9日 · 4:4:4 is uncompressed and therefore provides the best image quality, whereas 4:2:2 and 4:2:0 sacrifice color quality for a lower data rate. Chroma subsampling is a type of color compression that reduces data rate and file size.

2019年3月4日 · A signal with chroma 4:4:4 has no compression (so it is not subsampled) and transports both luminance and color data entirely. In a four by two array of pixels, 4:2:2 has half the chroma of 4:4:4, and 4:2:0 has a quarter of the color information available.

2018年5月29日 · The 4:2:2 signal will have half the sampling rate horizontally, but will maintain full sampling vertically. 4:2:0, on the other hand, will only sample colors out of half the pixels on the first row and ignores the second row of the sample completely.

2020年1月7日 · When it comes to digital video production, we often see 8-bit, 10-bit or even 12-bit presenting the spec of image processing. Sometimes you also find the numbers like 4:4:4, 4:2:2 and 4:2:0 on recording devices. What exactly do these numbers mean and how they affect the image quality and colors? We will answer all of your questions in this article.

2019年11月12日 · One thing 4's and 2's share in common is that they both feel a depth and width of emotions, but one key difference is that 4's are intimately aware of and in touch with their feelings, while 2's tend to put their feelings on the shelf so they can tend to other people.

2013年7月4日 · They're exactly the same metrically (i.e. any correct 4/4 measure will also be a correct 2/2 measure). The reason one would be used over the other is to communicate with the performer how the beats should be interpreted. 4/4 is generally felt to have 4 beats per bar, where 2/2 is generally felt to have 2.

2012年2月28日 · How can you play 2/2 in 2/4? 2/2 means 2 half-notes per measure, and 2/4 means two quarter notes per measure. They are in no way equal. If you say that you count 4 beats per measure in the 2/2, it is really "ONE-and-TWO-and". If you say that you think double tempo of what is written, it's alla breve, not 2/4.
