animethemes-batch-encoder

Description

Generate and execute collection of FFmpeg commands sequentially from external file to produce WebMs that meet AnimeThemes.moe encoding standards.

Take advantage of sleep, work, or any other time that we cannot actively monitor the encoding process to produce a set of encodes for later quality checking and/or tweaking for additional encodes.

Ideally we are iterating over a combination of filters and settings, picking the best one at the end.

Install

Requirements:

• FFmpeg
• Python >= 3.6

Install:

pip install animethemes-batch-encoder

Usage

    python -m batch_encoder [-h] [--generate | -g] [--execute | -e] [--custom | -c] [--file [FILE]] [--configfile [CONFIGFILE]] [--inputfile [INPUTFILES]] --loglevel [{debug,info,error}]

Mode

--generate generates commands from input files in the current directory.

The user will be prompted for values that are not determined programmatically, such as inclusion/exclusion of a source file candidate, start time, end time, output file name and new audio filters.

--execute executes commands from file in the current directory line-by-line.

By default, the program looks for a file named commands.txt in the current directory. This file name can be specified by the --file argument.

--generate and --execute generates commands from input files in the current directory and executes the commands sequentially.

None will give modes options to run.

Custom

--custom customizes options like Create Preview, Limit Size Enable, CRFs and Encoding Modes for each output file. Default configs are specified in the --file argument.

File

The file that commands are written to or read from.

By default, the program will write to or read from commands.txt in the current directory.

Config File

The configuration file in which our encoding properties are defined.

By default, the program will write to or read from batch_encoder.ini in the user config directory of appname batch_encoder and author AnimeThemes.

Example: C:\Users\Kyrch\AppData\Local\AnimeThemes\batch_encoder\batch_encoder.ini

Input File

--inputfile will give the option to insert input files in advance, separated by two commas. Example: python -m batch_encoder -g --inputfile 'source file.mkv,,source file 2.mkv'.

Audio Filters

• Exit Saves audio filters if selected and continues script execution.
• Custom Apply a custom audio filter string.
• Fade In Select an exponential value to apply Fade In.
• Fade Out Select a start position and an exponential value to Fade Out.
• Mute Select a start and end position to leave the volume at 0.

Video Filters

• No Filters Add a line without filter
• scale=-1:720 Add downscale to 720p
• scale=-1:720,hqdn3d=0:0:3:3,gradfun,unsharp Add downscale to 720p and filters by AnimeThemes
• hqdn3d=0:0:3:3,gradfun,unsharp Add filters by AnimeThemes
• hqdn3d=0:0:3:3 Add lightdenoise filter
• hqdn3d=1.5:1.5:6:6 Add heavydenoise filter
• unsharp Add unsharp filter
• Custom Apply a custom video filter string.

Encoding Properties

AllowedFileTypes is a comma-separated listing of file extensions that will be considered for source file candidates.

EncodingModes is a comma-separated listing of bitrate control modes for inclusion and ordering of commands.

Available bitrate control modes are:

• CBR Constant Bitrate Mode
• VBR Variable Bitrate Mode
• CQ Constrained Quality Mode

CRFs is a comma-separated listing of ordered CRF values to use with VBR and/or CQ bitrate control modes.

CBRBitrates is comma-separated listing of ordered bitrate values to use with CBR.

CBRMaxBitrates is comma-separated listing of ordered maximum bitrate values to use with CBR.

Threads is the number of threads used to encode. Default is 4.

LimitSizeEnable is a flag for including the -fs argument to terminate an encode when it exceeds the allowed size. Default is True.

AlternateSourceEnable is a flag for alternate command lines between source files. Default is False.

CreatePreview is a flag for create a command line to preview seeks. Default is False.

IncludeUnfiltered is a flag for including or excluding an encode without video filters for each bitrate control mode and CRF pairing. Default is True.

VideoFilters is a configuration item list used for named video filtergraphs for each bitrate control mode and CRF pairing.

Logging

Determines the level of the logging for the program.

--loglevel error will only output error messages.

--loglevel info will output error messages and script progression info messages.

--loglevel debug will output all messages, including variable dumps.
