tru story, DFW airport setup vertical boards for flight arrivals/departures right inside the entry gates when driving in. they had to take them down when someone got killed being rear ended looking at them.

What codec does netflix use, really need to know this for a thesis I am making on spergs.

for real it uses VC-1 if you use the web interface (for lots of older content) or on some older streaming devices, h.264 on mobile or newer streaming devices

what's wrong with 10bit? Is there a specific transcoding method to avoid color banding without 10bit? so if I were say taking the South Park movie and converting it to a Format so that I could watch it on my Chrome Book , what would I use?

10-bpc has 1024 steps between black and white.

If the source is 4:2:0 and has no banding, the new encode, if high enough bitrate, should not have banding either.

Banding is caused by not having any level of dithering, or noise to cover up the low resolution of the color channels

all consumer level video is delivered 4:2:0

codecs and containers are different things

codecs go inside containers

certain containers can only hold certain codecs

You're already dead

The Caimans video codec takes video quality for GBA to a new level thanks to multipass variable bitrate encoding, adaptive resolution changing and other advanced features you could expect to find only in high end video encoders for more powerful systems.
This page covers only Caimans codec Version 2.2, a new page with tech specs of Caimans codec pro should be out soon.

Multipass variable bitrate
Thanks to this advanced encoding techinque the user can choose the average bitrate or the final size of the encoded material and the Caimans codec will encode the footage exactly to match the requested average bitrate or to fit the requested size while giving more bitrate to the most complex scenes and saving it for static parts. This is a feature normally available only on high end mpeg encoders. The Caimans encoder does even better: you can also manually adjust the encoding parameters to give more bitrate to some particular sequences you care of, the Caimans encoder still averages to a bitrate that allows the whole encoded material to fit exactly in the requested space.

Dynamic resolution changing for very low bitrate encoding
For critical compression tasks, where the most compression is required at bitrates as low as 12-15Kbytes/sec, the Caimans encoder can dinamically decrease video resolution in the most complex parts of the footage to keep an acceptable quality even at high frame rates, and increase it in the most static parts; this is the same concept of the variable bitrate encoding but applied to the resolution instead of the bitrate. It is a "last resort" feature you can choose to activate when size really matters.

Dithering at play-time
Even if Gameboy advance only supports 32768 colors, the Caimans codec internally works in 24bit mode (16M colors). Starting from version 2.1 this addictional color information is used to perform a dithering at playtime, simulating the presence of more than 32768 colors. Expecially when working with computer generated images this feature greatly enhances the visual perception of the video. As an example let's take a look at the following picture:



The (A) frame shows the internal true color encoding of a Caimans video frame, (B) is the frame as it would be displayed by the gameboy without the use of dithering and finally (C) is the same frame displayed with the dithering function activated. As you can see expecially when looking at the floor, the (C) picture really looks like the true color source.
And here is a comparison between the Caimans codec and another GBA video codec not using dithering at play-time.



High frame rates
The Caimans codec can decode video up to 30 frames per second using only 70-80% of Gameboy Advance CPU.
High frame rates also means respect of the original frame rate, infact not all the video footage comes at 30 FPS, for example the Watchout movie, the Ornaments clip and most movie trailers are 24 FPS material, as you can see from the picture below (or you can download Watchout here, Ornaments here, and many movie trailers here, and check by yourself) so the caimans encoder performs a frame by frame compression, keeping exactly the original number of frames at the original frame rate. That's why you should not trust people saying "The decoding frame rate is kept constant to 30 FPS" or "x frames encoded at 30 FPS" even when dealing with 24 FPS material, because either they are cheating you, or they mean "Fakes Per Second" ;-)



Audio encoding
The Caimans codec 2.0 introduces a proprietary compressed audio system and can decode at frequencies ranging from 8 to 32 Khz at the highest quality you have ever heard on your GBA while using only 2 to 10 Kbytes/sec.

Low ram usage
Caimans codec can run either from iwram, ewram or rom and uses only 100 Kbytes of ram, including the space needed for the screen.
