usage: ld-decode [-h] [-s start] [--start_fileloc start_fileloc] [-S seek]
[-l length] [-p] [-n] [-m mtf] [--MTF_offset mtf_offset] [-j]
[--noDOD] [--noEFM] [--daa] [--ignoreleadout] [--verboseVITS]
[--lowband] [--WibbleRemover] [-t threads] [-f FREQ]
[--video_bpf_high FREQ] [--video_lpf FREQ]
infile outfile
Extracts audio and video from raw RF laserdisc captures
positional arguments:
infile source file
outfile base name for destination files
optional arguments:
-h, --help show this help message and exit
-s start, --start start
rough jump to frame n of capture (default is 0)
--start_fileloc start_fileloc
jump to precise sample # in the file
-S seek, --seek seek seek to frame n of capture
-l length, --length length
limit length to n frames
-p, --pal source is in PAL format
-n, --ntsc source is in NTSC format
-m mtf, --MTF mtf mtf compensation multiplier
--MTF_offset mtf_offset
mtf compensation offset
-j, --NTSCJ source is in NTSC-J (IRE 0 black) format
--noDOD disable dropout detector
--noEFM Disable EFM front end
--daa Disable analog audio decoding
--ignoreleadout continue decoding after lead-out seen
--verboseVITS Enable additional JSON fields
--lowband Use more restricted RF settings for noisier disks
--WibbleRemover PAL/digital sound: (try to) remove spurious ~8.5mhz
signal. Mitigate interference from analog audio in
reds on NTSC
-t threads, --threads threads
number of CPU threads to use
-f FREQ, --frequency FREQ
RF sampling frequency in source file (default is
40MHz)
--video_bpf_high FREQ
Video BPF high end frequency
--video_lpf FREQ Video low-pass filter frequency
FREQ can be a bare number in MHz, or a number with one of the case-insensitive
suffixes Hz, kHz, MHz, GHz, fSC (meaning NTSC) or fSCPAL.
ld-cut is a subset, with outfile being a raw 16-bit file or lds:
usage: ld-cut [-h] [-s start] [-l length] [-S seek] [-E end] [-p] [-n]
infile outfile
Extract a sample area from raw RF laserdisc captures. (Similar to ld-decode,
except it outputs samples)
positional arguments:
infile source file
outfile destination file (recommended to use .lds suffix)
optional arguments:
-h, --help show this help message and exit
-s start, --start start
rough jump to frame n of capture (default is 0)
-l length, --length length
limit length to n frames
-S seek, --seek seek seek to frame n of capture
-E end, --end end cutting: last frame
-p, --pal source is in PAL format
-n, --ntsc source is in NTSC format
