TAP CODE IS EASY

A F L Q V

(A)nother
(F)ine
(L)atex
(Q)ueen
(V)isits

The tap system simply requires one to know the alphabet and the short sequence "AFLQV" (the initial letter of each row), without memorising the entire grid. For example, if a person hears four knocks, they can think "A... F... L... Q". If after a pause there are three knocks, they think "Q... R... S" to arrive at the letter S. -Wikipedia

Today, with the release of Vulkan 1.3.302, Khronos is proud to announce two new Vulkan Video encode extensions. First, the Encode AV1 extension adds AV1 encode functionality to complement its existing AV1 decode support. Additionally, the new Encode Quantization Map extension introduces advanced encoding features for all supported codecs to Vulkan Video developers for the first time.

A question for any #digital #video experts out there... I'm confused as heck about the results from #libx265 (used via #ffmpeg, not the #x265 tool) regarding quality vs. preset and ratefactor.

I'm far from the first person to be confused by this, but I haven't found any real answers.

First I'll just show some analysis from some test encodes of a file; ssim and ratefactor numbers are coming from the CSV stats output of libx265.

1/x

#quality #preset #ratefactor #CRF #encode #encoding

Part of a table comparing structural similarity (SSIM) results and measured ratefactor vs preset choice and CRF encode factor.

These numbers come from libx265, which encodes video to h.265 AKA HEVC format.  

They were collected by encoding the same short sample file with a number of presets and Constant Rate Factor (CRF) settings, and using libx265's CSV stats output file.

The numbers are confusing, as they show that the "fast" preset gives higher video quality (as measured by SSIM) than the "slow" preset, despite the "fast" files being significantly smaller.  The standard deviation for SSIM is also smaller for the "fast" preset.

Revolutionary #Genetics Research Shows #RNA May Rule Our #Genome
Scientists discovered thousands of active RNA molecules control #human body: #ENCODE team reported that at least 75% of genome gets transcribed into RNAs. Some #biologists greeted announcement with skepticism bordering on outrage. ENCODE team was accused of hyping its findings; some critics argued that most of this RNA was made accidentally because enzymes are ndiscriminate about which bits of DNA it reads.

Суперсемейка против Unicode: Эластика и ее противник гибкий UTF-8

Кодировка символов – это про то, как символы которыми мы пишем наши сообщения выглядят в двоичном коде. В мире существует множество кодировок, но самые популярные из них, это; ASCII – это самая первая кодировка в мире, она была создана в Америке. Собственно благодаря ей, 8 бит равны 1 байт. UTF-8, 16 и 32 – данные кодировки были созданы организацией Unicode (Юникод). Если по простому, то они это то же самое что и ASCII, но более вместительные, что означает, что они занимают больше памяти. Все бы ничего, легкая тема, но есть одно но – кодировка UTF-8 имеет, как по мне, гениальную особенность: она умеет "растягиваться". То есть адаптироваться под большое кол-во символов.

Comparing compression in AV1, x264, and x265

I recently got it into my head to compare the various popular video codecs in an effort to better understand how av1 works and looks compared to x264 and x265. I also had ideas of using a intel video card to compress a home video security setup, and what levels of compression I would need to get good results.... #codec #comparison #quality #encode #av1 #x264 #x265
