RAW ML Formats to Workable Images/Movies Developer

I needed a workflow to provide me full control over development for filmmaking with Magic Lantern (beyond mlrawviewer's excellent preview!), while keeping things simple by providing defaults for everything. So, I wrote this: A converter from ML formats (RAW, MLV, DNG sequences) to many usable formats (EXR, DPX, and yes, Prores) with many, many features in between!

Generically, as a DNG developer, it's very capable as well, even if all the ML formats are ignored.

I make shorts with convmlv :D so here's some examples of it (back at v1.7) in action!!

http://youtu.be/yi-G7sXHB1M http://youtu.be/yi-G7sXHB1M

See http://www.magiclantern.fm/forum/index.php?topic=16799.0 for more info.

The pdf found in the source and in the release, under docs->docs.pdf, is up to date. Refer to it for tutorials, tips, documentation, etc.!!

Quick Fix: On Mac, running brew install --with-default-names grep may fix the MLV --> DNG lag, as reported by @mutex1980.

NOTE on Symbolic Linking: The filesystem that you're targeting with convmlv must support symbolic linking (though it might work without if you're not developing from DNGs).

Full help page is below:

	./convmlv.sh [FLAGS] [OPTIONS] files
	A program allowing you to develop ML files into workable formats. Many useful options are exposed.
	  --> Defaults: Compressed 16-bit Linear EXR. 10-bit Prores4444 MOV.
	  --> Color Defaults: Linear (1.0) Gamma on sRGB Gamut, using Camera White Balance.
	  --> Acceptable Inputs: MLV, RAW (requires raw2dng), Folder containing DNGs.
	  --> Option Input: From command line or config file (specify with -C).
	  --> Forum Post: http://www.magiclantern.fm/forum/index.php?topic=16799.
	  --> A note: BE CAREFUL WITH OPTIONS. Wrong values will give very strange errors. Read this page well!!
	It's as simple or complex as you need it to be: 'convmlv -m <mlvfile>.mlv' is enough for good-looking output!
VERSION: 2.0.1
	Place these in RES_PATH (see OPTIONS, BASIC). Keep in mind you also need dist. and pip packages.

	  --> 0: Auto WB (requires balance.py). 1: Camera WB (default). 2: No Change.
	  --> AWB uses the Grey's World algorithm.
	-A [i:i:i:i]		SHARP - Lets you sharpen, or blur, your footage.
	  --> BE CAREFUL. Wrong values will give you strange errors.
	  --> Size/Strength (S/T). S is the size of the sharpen/blur effect, T is the strength of the sharpen/blur effect.
	  --> Luma/Chroma (L/C). L is the detail, C is the color. Luma sharpening more effective.
	  --> Option Value: <LS>:<LT>:<CS>:<CT>
	  --> LS and CS must be ODD, between 3 and 63. Negative LT/CT values blur, while positive ones sharpen.
	  --> Strong Sharp: 7:3:7:3 Strong Blur: 7,-3:7,-3. Medium Sharp: 5:1:3:0

	  --> Specify -l multiple times, to apply multiple LUTs in sequence.
	-S [int]		SATPOINT - Specify the 14-bit uint saturation point of your camera. You don't usually need to.
	  --> Worth setting globally, as it's a per-camera setting. Must be correct for highlight reconstruction/unclipped highlights.
	  --> Lower from 15000 if -H1 yields purple highlights, until they turn white.
	  --> You can determine the optimal value using the max pixel value of 'dcraw -D -j -4 -T'.

	  --> How to: http://www.dl-c.com/board/viewtopic.php?f=4&t=686
	-F <path>		DARKFRAME - This is the path to a "dark frame MLV"; effective for noise reduction.
	  --> How to: Record 5 sec w/lens cap on & same settings as footage. Pass MLV in here.
	  --> If the file extension is '.darkframe', the file will be used as a preaveraged dark frame.
	-R <path>		darkframe_output - Specify to create a .darkframe file from passed in MLV.
	 --> Usage: 'convmlv -R <path> <input>.MLV'
	 --> Averages <input>.MLV to create <path>.darkframe.

	  --> Manually place all in RES_PATH. See http://www.magiclantern.fm/forum/index.php?topic=16799.0 .
	INTRO Images aren't simple. They are often stored, processed, and viewed as a result of complex transformations usually called, 
	in applications, color management. Understanding it is required as a colourist, and encouraged as a DPs and Cinematographers.
	--> Intro: http://www.cambridgeincolour.com/tutorials/color-management1.htm
	--> Understanding Gamma: http://www.cambridgeincolour.com/tutorials/gamma-correction.htm
	--> Color Spaces: http://www.cambridgeincolour.com/tutorials/color-spaces.htm

	--> Monitor Calibration: http://www.cambridgeincolour.com/tutorials/monitor-calibration.htm
	PIPELINE convmlv is a color managed application, designed to retain quality from RAW footage:
		-- mlv_dump writes camera-specific color transformation matrices as metadata in developed DNGs.
			--> This defines the camera's gamut.
		-- dcraw applies these matrices, then transforms the newly developed image to the super-wide XYZ colorspace.
			--> All color detail is preserved, and if now in a well-defined colorspace.
			--> No gamma has been applied - the image is now Linear XYZ.
		-- ffmpeg applies the specified (up to) x64 resolution 3D LUTs, in .cube format.
			--> Use -g and -G to specify Gamma/Gamut combinations.
			--> The output employs DATA, not LEGAL, values. The resulting image is flatter, but retains all shadow/highlight detail.
			--> -l specified LUTs are applied afterwards.
	3D LUTS The included LUTs, found in the convmlv repository, are key to convmlv's color management solution:
		-- color-core: The required LUTs, including sRGB (default), Adobe RGB, and Rec709 in Standard and Linear gamma.
		-- color-ext: Optional LUTs, including Rec2020, DCI-P3, etc. in Standard/Linear gammas, but also in Log formats.
	Create Your Own LUTs using LUTCalc, for any grading format output: https://cameramanben.github.io/LUTCalc/ (watch his tutorials).
	 --> Note that convmlv only accepts up to 64x64x64 LUTs. You can resize LUTs using pylut (https://pypi.python.org/pypi/pylut).
	 --> The pylut command to resize is 'pylut <yourx65lut>.cube --resize 64'. Alternatively, you can use pylut from Python (2X only).
	 --> I reccommend Legal --> Data LUTs, as this conserves shadow/highlight detail for grading. Legal --> Legal looks better, but with detail loss.
	Config files, another way to specify options, can save you time & lend you convenience in production situations.
	GLOBAL: /home/sofus/convmlv.conf
	LOCAL: Specify -C/--config.
		Most options listed above have an uppercased VARNAME, ex. OUTDIR. You can specify such options in config files, as such:
		One option per line only. Indentation by tabs or spaces is allowed, but not enforced.
		Comments Lines starting with # are comments.
		You may name a config using:
			CONFIG_NAME <name>
		Flags If the value is a true/false flag (ex. IMAGE), simply specifying VARNAME is enough. There is no VALUE.
	OPTION ORDER OF PRECEDENCE Options override each other as such:
		-LOCAL options overwrite GLOBAL options.
		-COMMAND LINE options overwrite LOCAL & GLOBAL options.
		-FILE SPECIFIC options overwrite ALL ABOVE options.
	File-Specific Block: A LOCAL config file lets you specify options for specific input names:
			...options here will only be 
		You must use the truncated (no .mlv or .raw) input name after the /. Nested blocks will fail.
		With a single config file, you can control the development options of multiple inputs as specifically and/or generically
		as you want. Batch developing everything can then be done with a single, powerful commmand.
