  2. 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: vimeo.com/115534648

    Follow me on http://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.
