How Codecs Work - Tutorial

If you work with video, it’s vital to understand how codecs work and how they change your image. In this tutorial, I cover all of the big concepts behind codecs, breaking it down into understandable pieces. While the nitty-gritty of compression algorithms can get complicated, all of the main ideas are quite simple. Part two of this series is here: https://vimeo.com/115534648

Follow me on facebook.com/davidkongfilm for the latest updates.

Here’s an overview of the topics covered:

– What a codec is – And how it differs from a container. – Different types of codecs – And why I frequently use 4 different codecs on a single project. – Bit Depth – What it means and why it matters. – Chroma Subsampling – 4:4:4, 4:2:2, and 4:2:0, and when it becomes an issue. – Spatial Compression and Blocking – One of the most common artefacts you see with normal work. – Temporal Compression – Long-GOP codecs, inter-frame compression, and ALL-I codecs. – Lossless vs. Lossy compression – How image compression differs from data compression. – Bit Rate – How to calculate bit rates and the differences between kbps/kBps/Mbps/MBps. – Raw – Briefly, the difference between Raw, compressed, and uncompressed video.

Scientists have figured out how to store digital images in DNA

DNA – or deoxyribonucleic acid, to give it its full title – is one of the basic biological building blocks of all living organisms, containing the genetic code that plays a large role in making us who we are. And now scientists have managed to use the same molecules to store digital photographs and retrieve them intact.

    If the process can be refined and scaled up, that means we could…
