-# Low-Efficiency Video Codec
-
-The codec compresses image sequences by avoiding redundancies by reusing parts
-of previous frames. A frame is one block that is then subdivided further as
-needed.
-
-## Literal-Block
-
-Stores the pixels' RGB values as is.
-
-## Split-Block
-
-Delegates to two sub-blocks. The block is split orthorgonally on the longest
-axis. If needed, the left/top block is rounded down and the right/bottom.
-
-## Reference-Block
-
-Indicates that parts of the last frame are reused. The data reused is at the
-position of this block in the last frame with the translation added.
-
-## Advanced-Reference-Block
-
-Like Reference-Block but instead translates by non-integer amount of pixels,
-applying a 2x2 matrix from the center of the block and multiplying the color
-value of each component, interpolating if necessary.
-
-## Compressed-Literal-Block
-
-_**JPEG? just DCT? idk**_
-
-## File format
-
-- magic bytes: `5e b1 c3 08`
-- resolution: _`u16, u16`_
-- frame count: _`u64`_
-- frames (repeated [frame count]-times)
-  - block kind: _`u8` (see tags below)_
-  - block: _one of the following_
-    - 0 **Literal-Block**
-      - pixels: _`[[u8; 3]; (inferred)]`_ (stored line-by-line)
-    - 1 **Compressed-Literal-Block**
-      - length: _`u32`_
-      - data: _`[[u8; length]`_
-    - 2 **Split-Block**
-      - sub-blocks: _`[block; 2]` (see above)_
-    - 3 **Reference-Block**
-      - translation: _`i8, i8`_
-    - 4 **Advanced-Reference-Block**
-      - translation: _`s8, s8`_ (translation)
-      - transform: _`s8, s8, s8, s8`_ (2x2-matrix applied before sampling
-        relative to the center)
-      - value_scale: _`i8`_ (multiplication of each color component by $1.05^n$)
-
-### Data Types
-
-- _`u<n>`_: unsigned n-bit integer (little-endian)
-- _`i<n>`_: signed n-bit integer using twos-complement (little-endian)
-- _`s8`_: 8-bit scalar. When read as _`i8`_ represents a value of
-  $\frac{x}{|x|} * \sqrt{2}^{|{x}| - 4}$ for $x \neq 0$, otherwise 0
-- _`[<T>; <N>]`_: Array of T with length N
