Usage:
./convmlv.sh [OPTIONS] mlv_files
INFO:
A script allowing you to convert .MLV, .RAW, or a folder with a DNG sequence into a sequence/movie with optional proxies. Images
are auto compressed. Many useful options are exposed, including formats (EXR by default).
VERSION: 1.8.1
DEPENDENCIES: If you don't use a feature, you don't need the dependency, though it's best to download them all.
-mlv_dump: For DNG extraction from MLV. http://www.magiclantern.fm/forum/index.php?topic=7122.0
-raw2dng: For DNG extraction from RAW. http://www.magiclantern.fm/forum/index.php?topic=5404.0
-mlv2badpixels.sh: For bad pixel removal. https://bitbucket.org/daniel_fort/ml-focus-pixels/src
-dcraw: For RAW development.
-ffmpeg: For video creation.
-ImageMagick: Used for making proxy sequence.
-Python 3 + libs: Used for auto white balance.
-exiftool: Used in mlv2badpixels.sh.
OPTIONS, BASIC:
-v version - Print out version string.
-o<path> OUTDIR - The path in which files will be placed (no space btwn -o and path).
-M<path> MLV_DUMP - The path to mlv_dump (no space btwn -M and path). Default is './mlv_dump'.
-R<path> RAW_DUMP - The path to raw2dng (no space btwn -M and path). Default is './raw2dng'.
-y<path> PYTHON - The path or command used to invoke Python. Defaults to python3.
-B<path> MLV_BP - The path to mlv2badpixels.sh (by dfort). Default is './mlv2badpixels.sh'.
-T[int] Max process threads, for multithreaded parts of the program. Defaults to 8.
OPTIONS, OUTPUT:
-i IMAGE - Specify to create an image sequence (EXR by default).
-f[0:3] IMG_FMT - Create a sequence of <format> format. 0 is default.
--> 0: EXR (default), 1: TIFF, 2: PNG, 3: Cineon (DPX)."
-c COMPRESS - Specify to turn ***off*** automatic image compression. Auto compression options otherwise used:
--> TIFF: ZIP (best for 16-bit), PIZ for EXR (best for grainy images), PNG: lvl 9 (zlib deflate), DPX: RLE.
--> EXR's piz compression tends to be fastest + best.
-m MOVIE - Specify to create a Prores4444 video.
-p[0:3] PROXY - Specifies the proxy mode. 0 is default.
--> 0: No proxies. 1: H.264 proxy. 2: JPG proxy sequence. 3: Both.
--> JPG proxy won't be developed w/o -i. H.264 proxy will be developed no matter what, if specified.
-s[0%:100%] PROXY_SCALE - the size, in %, of the proxy output.
--> Use -s<percentage>% (no space). 50% is default.
-k KEEP_DNGS - Specify if you want to keep the DNG files.
--> If you run convmlv on the dng_<name> folder, you will reuse those DNGs - no need to redevelop!
-E<range> FRAME_RANGE - Specify to process only this frame range.
--> DNGs will still all be generated. Use -k to reuse a previous iteration to get past this!
--> <range> must be written as <start>-<end>, indexed from 0 to (# of frames - 1).
--> If you write a single number, only that frame will be developed.
OPTIONS, RAW DEVELOPMENT:
-d[0:3] DEMO_MODE - DCraw demosaicing mode. Higher modes are slower. 1 is default.
--> Use -d<mode> (no space). 0: Bilinear. 1: VNG (default). 2: PPG. 3: AHD.
-r FOUR_COLOR - Interpolate as four colors. Can often fix weirdness with VNG/AHD.
-H[0:9] HIGHLIGHT_MODE - 2 looks the best, but can break. 0 is a safe bet.
--> Use -H<number> (no space). 0 clips. 1 allows colored highlights. 2 adjusts highlights to grey.
--> 3 through 9 do highlight reconstruction with a certain tone. See dcraw documentation.
-C[0:3] CHROMA_SMOOTH - Apply chroma smoothing to the footage, which may help ex. with noise/bad pixels.
--> 0: None (default). 1: 2x2. 2: 3x3. 3: 5x5.
--> Only applied to .MLV files.
-n[int] NOISE_REDUC - This is the threshold of wavelet denoising - specify to use.
--> Use -n<number>. Defaults to no denoising. 150 tends to be a good setting; 350 starts to look strange.
-g[0:4] SPACE - This is output color space. 0 is default.
--> Use -g<mode> (no space). 0: Linear. 1: 2.2 (Adobe RGB). 2: 1.8 (ProPhoto RGB). 3: sRGB. 4: BT.709.
-S SHALLOW - Specifying this option will create an 8-bit output instead of a 16-bit output.
--> It'll kind of ruin the point of RAW, though....
OPTIONS, COLOR:
-w[0:2] WHITE - This is a modal white balance setting. Defaults to 0. 1 doesn't always work very well.
--> Use -w<mode> (no space).
--> 0: Auto WB (Requires Python Deps). 1: Camera WB. 2: No Change.
-A[int] WHITE_SPD - This is the amount of samples from which AWB will be calculated.
-->About this many frames, averaged over the course of the sequence, will be used to do AWB.
-l<path> LUT - This is a path to the 3D LUT. Specify the path to the LUT to use it.
--> Compatibility determined by ffmpeg (.cube is supported).
--> LUT cannot be applied to EXR sequences.
--> Path to LUT (no space between -l and path).
OPTIONS, FEATURES:
-u DUAL_ISO - Process file as dual ISO.
-b BADPIXELS - Fix focus pixels issue using dfort's script.
--> His file can be found at https://bitbucket.org/daniel_fort/ml-focus-pixels/src.
-a<path> BADPIXEL_PATH - Use, appending to the generated one, your own .badpixels file.
--> Use -a<path> (no space). How to: http://www.dl-c.com/board/viewtopic.php?f=4&t=686
-F<path> DARKFRAME - This is the path to the dark frame MLV, for noise reduction.
--> This is a noise reduction technique: Record 5 sec w/lens cap on & same settings as footage.
--> Pass in that MLV file (not .RAW) as <path> to get noise reduction on all passed MLV files.
--> If the file extension is '.darkframe', the file will be used as the preaveraged dark frame.
OPTIONS, INFO:
-e Output MLV settings.
-K Debian Package Deps - Lists dependecies. Works with apt-get on Debian; should be similar elsewhere.
--> No operations will be done.
--> Example: sudo apt-get install $ (./convmlv -K)
-Y Python Deps - Lists Python dependencies. Works with pip.
--> No operations will be done.
--> Example: sudo pip3 install $ (./convmlv -Y)
-N Manual Deps - Lists manual dependencies, which must be downloaded by hand.
--> There's no automatic way to install these. See the forum post.
