 ====== Video ======
-Almost all the video is compressed.
+See [[ffmpeg:ffmpeg|ffmpeg]]
-Raw, uncompressed video is just too big and would waste too much bandwidth.
+----
-Common compression:
-  * MPEG-1: Used for Video CDs
-  * MP3: Part of the MPEG-1 standard, ubiquitous today
-  * MPEG-2/H.262: Used for DVD and other digital mediums
-  * MPEG-4 Part 10/H.264: Used in Blu-ray
-  * MPEG-H/H.265: The next generation encoding format with support for 4K and 8K resolutions
-After H.264 came H.265. It also has a few other names, most commonly High Efficiency Video Coding (HEVC) or MPEG-H.
-H.265 doubles the data compression ratio compared to H.264 and can support resolutions up to 8192×4320.

-This means that video at the same quality needs only half of the bandwidth (or file size).  Alternately, it means that the quality of the video can be substantially improved at the same bit rate, something very important for very high definition (i.e. 4K and 8K) displays,
