AV1 codec GUI design

I could need some help with the GUI design for the AV1 codec, the documentation is not very helpful...

I've edited the AV1 help output with some sublime text tricks like multi cursor and regex search/replace to get a simple format that will serve to generate the needed code.

I hope somebody can help, this is what I got so far:

A simple boolean option is defined like so:

Code:
--debug
text: Debug
type: bool
help: Debug mode (makes output deterministic)

a string option like so:

Code:
--output
text: Output
type: string
help: Output filename

a numeric option like so:

Code:
--cpu-used
text: CPU Used
type: numeric
min: 0
max: 8
help: CPU Used (0..8)
instead of numeric type can also be int or float


options:

Code:
--bit-depth
text: Depth
type: option
help: Bit depth for codec (8 for version <=1, 10 or 12 for version 2)
options: 8, 10, 12

integer options:

Code:
--aq-mode
text: AQ Mode
type: int option
help: Adaptive quantization mode
options: off, variance, complexity, cyclic refresh
