This video goes through the very top-level basics of how videos work. Most of the discussion is hardware-agnostic, talking about video encode, decode, and compression. At GN, none of us are experts in these topics (and they exit our usual coverage spectrum), so graphics engineer Tom Petersen will be joining to help provide the foundational knowledge as a part of our educational series of engineering discussions. Towards the end, he talks about the hardware-level choices that affect media processing. This is the last of our series of 3 videos with Tom Petersen. Check the others below, and check back for videos with other engineers later!

Hey everyone! This is our third and final installment of educational deep dives with Tom! You can watch our previous two below. We'll have some other industry engineer videos from NVIDIA and case manufacturers coming up. I'm working on booking something technical with AMD hopefully in the near future as well! Aside from the big 3 silicon companies, what other engineering professions within the industry would you like to see on this channel? Even if I'm not familiar with the subject matter, I can study enough of it to at least interview someone for the basics like this! Watch our educational video on graphics/video drivers and game optimization: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Qp3BGu3vixk.html Watch the video on Simulation Time Error & Presentmon: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-C_RO8bJop8o.html

Small correction: YUV 4:4:4 / 4:2:2 / 4:2:0 doesn't describe bits, it describes how many chroma samples are stored. The first '4' says that we are talking about rows of 4 luma samples, the second number describes how many chroma samples are stored in the first of two lines and the second number how many chroma samples are stored in the second line. That means a 4×2 block of luma samples contains • 8 pairs of chroma samples in YUV 4:4:4 • 4 pairs of chroma samples in YUV 4:2:2 • 2 pairs of chroma samples in YUV 4:2:0 Another way to think about it is that in YUV 4:4:4, each luma sample has its own pair of chroma samples, in YUV 4:2:2, each 2×1 block of luma samples shares a pair of chroma samples (the chroma planes have full vertical but half horizontal resolution) and in YUV 4:2:0, each 2×2 block of luma samples shares a pair of chroma samples (the chroma planes are half horizontal and half vertical resolution).

@krakow10 Месяц назад

4:2:0 is truly a nonsensical shorthand made by an insane person. Because 4:2:2 and 4:2:0 are the only ones that realistically exist, you could just as easily describe the stored chroma resolution of a 2x2 square of chroma pixels instead of the insane self-referential sample numbers, for example: YUV 2x2 = YUV 4:4:4 YUV 1x2 = YUV 4:2:2 YUV 1x1 = YUV 4:2:0 Even if you argue that you must keep the 4x2 rectangle, describing the stored resolution still works and is way less insane than the "number of changes of chrominance samples between first and second row" like bruh

Computerphile did an introduction on DCT a few years ago going into more details of the math and intuition of the algorithm, in their 3 part series of covering JPEG compression. For those interested, it is a series worth a watch, as video compression seems to be very similar to JPEG compression on differences between frames.

WRT frequency domain on images. Picture it like this: the corner (0,0) is 0 oscillations -- constant value. the pixel at (0,1) has zero horizontal frequency, but 1 oscillaiton on the vertical, meaning it starts at 1, goes to 0, then back to 1, sine wave style (well, cosine actually but you get the idea, it's smooth and connects cyclically end to end). the pixel at (0,2) is the same but has two oscillations vertically, and so on. This step is usually performed on small blocks, 8x8 or 16x16. So on a block of 8x8, the frequency pixel at (8,8) is a checkerboard, and (0,8) is a series of 8 horizontal lines black white black white etc. the bottom right pixel (N,N) on any resolution ALWAYS coincides with the pattern that gives you a checkerboard.

@WUreta Месяц назад

Edit: Welp, I tried to explain Frequency Quantization and Symbol coding when PAT did it better... When they talk doing it in the residual, that's another layer of optimization in newer video codes, as it works the same as with JPEG images. Just to expand on it, as this was a moment of realisation for me when studying this JPEG compression: For each block of 8x8 pixels of the original image, we will assign a concrete "checkerboard/frequency" coefficient value. Meaning, if the first 8x8 are mostly black, they will recieve the coefficient (0,0). As this is a standard, we know that if we recieve (0,0) this can be reconstructed directly to a set of 8x8 pixels. If you zoom in all the way, you can appreciate the DCT patterns. We can apply a low-pass filter (reducing sharpness) and then can compress further by assigning compression algorithms to how many bits are needed for each coefficient. Meaning that coefficients that are more common (low frequencies), will use fewer bits that higher frequency ones. I probably have some of this mixed up as this was some time ago, but it was cool understanding how videos are compressed.

Frequency domain analysis is an extremely fun branch of math that has applications in so much stuff Circuits, sound, images, video You can view any information as a combination of several waves and instead of analyzing the signal you study its frequency components One of the steps there is the same as doing a low pass filter in audio, except high frequency in images correspond to sudden changes in values. Clipping it blurs the image (or whatever the equivalent is in YUV) Doing a high pass filter meanwhile is an useful way to get any edges which is useful for image recognition algorithm/AI but makes the image look like a normal map (that's tangent space, not frequency space, but hey)

Learning about compression and encoding/decoding requirements when I started running Plex and Jellyfin almost broke me.

I only have a very high level understanding of video encode/decode, so it always melts my brain just how insanely complex it all is, and just how smart everyone is to not only come up with the theory, but then turn that into actual silicon and software to seamlessly perform these tasks This video did a great job of getting deeper into the weeds of it all without being overwhelming and still very interesting, but then again, I'm pretty sure Tom reading a phone directory would be just as fascinating 😂
