Command List
This command list has every command under vhs-decode/cvbs-decode/hifi-decode/ld-decode and secondary items such as key scripts and the ld-tools suite.
These must be set for any decoder to work period.
- Frequency (Sample rate of Input RF data files)
- Tape Format (VHS or Video8 etc)
- TV System (Defines tape speed & colour system)
- Input & Output (Input files & Output names either local folder or full path)
Example Command
-f, frequency Manual setting of Input Frequency in integers of hz, mhz, ghz or 4fsc/5fsc/8fsc/10fsc (or CXADC Designators) the default is 40msps 16-bit the rate the DomesDayDuplicator uses (decoder is 8-bit/16-bit agnostic & 10-bit packed is unpacked automatically)
--tf, --tape_format Sets tape format to decode VHS, SVHS, UMATIC, UMATIC_HI, Hi8, Video8, BETAMAX, BETAMAX_HIFI, EIAJ, TYPEC, VCR (default is VHS) Tape Formats List
Note
BETAMAX_HIFI is for tapes with a HiFi FM track, for Linear audio tapes use just BETAMAX.
--no_resample Experimental Skips internal resampling to 40mhz, allows for native use of lower sample rates i.e 16-28msps and faster decoding.
-t, --threads Threads Sets Number of CPU processing threads default is 1, there is no limit but decoding will only utilise 6-8 threads at upto 10fps observed on x86 and upto 16fps on Apple M2 Silicon.
Note
Decoding is primarily single-core & cache speed biased due to the TBC code.
--use_saved_levels Experimental Skips doing most of the level detect code on each frame and only does it at the start or if there are issues detecting syncs. Provides a speedup in decoding and seems to work okay on captures that only have one single recording of media.
--level_detect_divisor (Default 2) Experimental (May lower processing time)
Currently, 1-6 value, 1 every sample, 2 every other sample and so on, Changes vsync serration code only use every nth sample when determining sync/blank levels higher value lower accuracy.
--debug Outputs full debug logging with timestamps, helpful for damaged tapes or keeping track of frames and decode time, costs a small but relatively negligible amount of extra processing time.
--skip_hsync_refine Skip refining line locations using hsync, less accurate line start detection but may avoid issues in some cases..
--dp & --debug_plot Do a plot for the requested data, separated by whitespace. Current options are: "
+ plot_options
+ ".",
--dp deemphasis Shows the deemphasis curve (note it's not very detailed atm and think it might just show 0-Nyquist rather than properly labelled)
--dp demodblock Displays Raw Demodulated Frequency Spectrum Graphs, makes a pop-up window per each thread so -t 32 would give you 32 GUI windows etc
-s, --start Jumps ahead to any given frame in the capture.
--start_fileloc Jumps ahead to any given sample in the capture.
-l, --length Limits decode length to n frames.
--overwrite Overwrite existing decode files if present.
--sl, --sharpness Sharpness Level 0-100 Value sets the level of visual sharpness, default 0, Higher values are better suited for plain, flat images i.e. cartoons and animated material, as strong ghosting can occur and or excessive noise (akin to cranking up the sharpness on any regular TV set.)
--ire0_adjust Automtically adjust the black level on a per-field basis, using the back porch level. Unlike --clamp this is done after time base correction. Therefore it can fix the per-field variations caused by the slight carrier shift of VHS-HQ and S-VHS. (more info)
-L,--level_adjust Multiply top/bottom IRE in JSON by 1 +/- this value controls Black/White video levels, adjustment can be used to avoid clipping on RGB conversion in chroma decode.
--recheck_phase Re-check chroma phase on every field, useful for multiple recordings on one single VHS tape for example. (No effect on U-matic)
--drh, --disable_right_hsync Horizontal Sync Check, Corrects warping in the horizontal lines and corrects the line start position of the video frame, this option Disables the use of the right side of hsync for lineloc detection (old behaviour)
--noAGC (deprecated, already disabled by default) Disables Automatic Gain Control image brightness/gamma levels use if fluctuating
--AGC Enables Automatic Gain Control
--ct, --chroma_trap Enables Chroma Trap Intended to reduce chroma interference on the main luma signal, Recommended to use if seeing banding or checkerboarding on the main luma .tbc in ld-analyse.
--y_comb Enables Y Channel comb filter (Luminance), optionally specifying IRE limit like --y_comb 5 this option is used to eliminate crosshatch/diamond patterns sometimes found in decoded images.
--nocomb Disables Croma Combing, Disable's internal chroma comb filter.
--sclip --sync_clip Enables Sync Clipping
--nodd Disable diff demod
--nld, --non_linear_deemphasis Can help reduce ringing and oversharpening. (WIP). (Used for hi-band formats and VHS LP/SP)
--sd, --sub_deemphasis Enables non-linear sub deemphasis. (WIP).
--skip_chroma Don't output chroma even for formats that may have it and possibly skip some of the chroma processing.
--export_raw_tbc Export a raw TBC without deemphasis applied, intended for filter tuning.
-D, --dod_t, --dod_threshold_p RF Dropout level fraction Threshold for dropouts in percentage of average (in decimal)
--noDOD Disables Drop Out Detection Default is on. (But processed after the fact with ld-dropout-correct/gen_chroma_vid scripts)
--dod_h, --dod_hysteresis The RF level needs to go above the dropout threshold multiplied by this for a dropout to end.
--dod_t_abs, --dod_threshold_abs RF Dropout level threshold absolute value.
Note
RF levels vary greatly between tapes & recording setups.
--clamp Enable blanking DC offset clamping/compensation, disabled by default can improve if video white level is extremely high.
--fm_audio_notch Applies an extra layer of filtering on the video signal for tapes with HiFi FM tracks that may cause interference on the picture signal.
--noclamp Disables blanking DC offset clamping/compensation.
--fallback_vsync Enable vsync detect fallback. (Will be enabled by default after further testing)
--cafc Chroma Automatic Frequency Control (AFC) Enables, down-converted chroma carrier AFC, implies --recheck_phase
-T If set to 0 or 1, force use of video track phase.
--high_boost Multiplier for boost to high RF frequencies uses default if not specified, can improve if black streaks are appearing in decodes, at cost of sharpness. (May change)
NTSC VHS Tape with high frequency dropouts
Tape corrected with --high_boost 5
--notch define the centre frequency for the optional built-in notch "bandpass" filter.
--notch_q define Q factor Intended primarily for reducing noise from interference however, the decoder logic already compensates based on tape type and TV System values.
--params_file <filename> Changes the decoder settings to use an external .json file with the correct formatting, allowing for easy editing and testing with external files rather then editing code directly useful for binary's and manually compiled versions of the decode suite.
Example:
Create a new text file, use this template and then save it as a custom-params.json file.
Note these values vary by tape format & TV System please read Advanced Parameter Adjustment for examples.

(Semi-Deprecated due to ld-process-vbi support)
Thanks to FFmpeg we have a useful filter to read this data in software, although it is technically human readable.
Simply edit the below commands and replace "input.tbc" / "input.mkv" and "output.mkv" / "vitc.txt" with your input files and desired output name.
ld-process-vbi
You will see the HH:MM:SS:FF counter at the bottom of ld-analyse when viewing the TBC files.
ffmpeg -i input.mkv -vf "readvitc=scan_max=-1,metadata=print:file=vitc.txt" -f null -
This will make a human-readable .txt file if the filter correctly detects the data.
.TBC to Luma (Black & White) only.

Say for some reason you have a source file in a certain format that you are either piping or otherwise can't change the extension of to get *-decode to recognize the datatype.
You can use mkfifo to create a named pipe to overcome this.
Example: mkfifo link.u8
flac -d u8capture.flac --force-raw-format --endian=little --sign=unsigned -o link.u8 -f |vhs-decode link.u8 out/u8capture
ld-chroma-decoder is used to render the TBC to a full-colour video file you can render to y4m or pipe to FFmpeg.
The chroma-decoder can use over 20GB of ram if available and can run in real-time on fairly modern systems.
The decoder has lots of options that can be tweaked but the list of pre-made commands below will get you started with a good basic export with proper interlaced flagging.
Use ld-chroma-decoder -h to list all the options available to the decoder.
Replace INPUT.tbc and OUTPUT.mkv with your desired names.
For standard output this list of export commands is provided you only need to change setdar=4/3 to setdar=16/9 for widescreen content.
- Active + VBI area
- FFV1 (4:2:2) (Lossless Compressed)
- V210 (4:2:2) (Uncompressed)
- ProRes HQ (4:2:2) (Visually Lossless)
- Y4M (4:4:4) (Uncompressed)
- V410 (4:4:4) (Uncompressed)
- ProRes 4444QX (4:4:4) (Visually Lossless)
(Y4M Only*) you can use these 2 commands.
