Audion Media Tools — changelog

Русский · About · User guide

3.0.0 — 15 October 2026

A new window. The window is a program of its own — C# on Avalonia, App\AudionMediaTools.exe, started by Start.exe. The engine runs for the time of an operation and is gone after it; nothing stays in the background.

The window is the face of the console command. Every button is an operation of media_cli.cmd, and a run opens in the journal with the command that repeats it. The command does everything the window does:

• describe — the operations, their fields, choices, presets;
• run --operation ID --set NAME=VALUE with --source, --target, --result (the outcome as JSON), --dry-run

(the commands it would start), --cancel-file, --only;

• wrapper NAME, map, components, plan, version;
• exit codes 0 done, 1 failed, 2 a wrong call or a run refused before it began, 130 stopped.

An interlaced source becomes progressive. EDITING, STORAGE, DELIVERY and COLOR turn a source of two fields into progressive frames by bwdif - by default a frame of each field, 50i to 50p; a frame of each frame, or the fields kept, are choices in Advanced. A progressive source is not touched, ARCHIVE keeps the fields.

Sections and modes. The ribbon holds AUDIO, ENCODE (archive, editing, storage, delivery), PACKAGE, CUT, FRAME RATE, COLOR and DOWNLOAD, each with its modes. DETAILS tells what the files of the Source are; SERVICE holds the checks and the installers. Every section and mode keeps its own form, remembered between launches; only the encoder and the decoder are shared. ↺ brings a mode back to its preset; COMMAND shows the commands of the run without running them.

The header and SETTINGS. The versions of yt-dlp, Deno, mpv, FFmpeg and the video card driver stand in the header; a newer yt-dlp, Deno or mpv is marked. SETTINGS: four looks, the fonts of the window and of the terminal, the components with UPDATE and INSTALL, the system — processor, video card and driver, memory, the FFmpeg coders that passed the check, the disk. ABOUT names the version, the folders, the author and the licence of every part.

The journal. The lines of a run come in the colours of the program that writes them. FFmpeg's own progress line frame= … speed= stands under the [PROGRESS] bar, in the window and in a console, and its last word Lsize= ends the file. The journal widens, and its width is remembered. The COMMAND line at the bottom runs a command of your own in the PowerShell 7 of the program (App\AudionPs.exe) or in cmd.exe.

The folders are input and output. The Source by default is input\, the Target output\; downloads go to output\Download, the list of links is input\urls.txt. Beside the paths: history, pin, RESET, LIST, TO SOURCE (the result becomes the next Source) and CLEAR — through the Recycle Bin, after a question that names the folders.

CUT. The window drives mpv itself: open, take A and B, mark IN or OUT, a split point taken only forward, the points only of the file chosen. A timecode is typed through a mask — digits one after another, the separators come by themselves. A sound file is cut without loss by default.

DOWNLOAD. PASTE beside the link, the list file and the cookies file; ⓘ shows the formats a link offers without downloading; cookies come from a browser or from a file sealed with DPAPI (the shield). A link to a video in a playlist takes the video alone unless the playlist is asked for.

The 95 wrappers of Scripts\ keep their names and run through media_cli.cmd wrapper. Each has its description in both languages, and the list of wrappers gives the same call through run.

Documents made from the program. Operations — every field, choice and preset with its tooltip — and Wrappers are written by media_cli.cmd map --docs from the data of the program. New: the console command and the guide for an AI agent.

Fixed.

• FRAME RATE and CUT take the declared rate of a constant-rate file: a ProRes LT averaging 24.016 at 23.976 was

slowed by 0.17 %, and a cut missed the frame grid.

• "1080p H.264 with AAC" and "for upload" downloads took Opus sound; they take AAC now.
• The 5.1 downmix of the wrappers (front whole, centre −3, rear −6 dB, no LFE) is a field of AUDIO

(downmix_formula); the plain -ac 2 of FFmpeg is 7.6 dB quieter on full 5.1.

• The _sync wrappers even the timestamps again (audio_resync); the ProRes wrappers of COLOR encode the sound to AAC

384k.

• A wrapper of two runs (the sound of videos, then sound files) no longer fails on a folder of one kind: a run without

files of its own is passed by.

• A file stopped halfway is never left under its final name: a file is written under name.writing.ext and takes its

name only whole.

• Empty folders a run made in the Target are taken away after it.
• DETAILS tells an interlaced rate (25i) and a variable one (VFR 30 (avg 28.875)), and names a file it cannot read

or that another program holds.

• --dry-run of an operation that cannot only say its commands is refused instead of running for real; a dry run

sets only the dry-run field of its own operation.

• A second run into the same Target with Overwrite off no longer reads as written: a file already there is passed by

before FFmpeg is started ([SKIP] … already exists and Overwrite is off) and counted in skipped, in ENCODE, AUDIO, PACKAGE, FRAME RATE and COLOR as in CUT.

• The bar of a run follows FFmpeg's own progress inside a file; it stood near 8 % through a one-file encode.
• Profile Doctor knows the wrappers of CUT: four ff-trim-* were reported as errors.
• The outcome of a download names the files it wrote (downloaded) and their count (processed).
• CUT keeps the frames asked for in a file whose timeline does not start at zero (MPEG-TS, an MP4 with an offset, ARRI

MOV): the start of the file was added to the seek twice. The top-up of a short tail works with Overwrite off.

• A result that would be one of its own sources - by its path, a link or a hard link - is refused before FFmpeg starts.
• A file is written under a draft name of its own run: a file that only looks like a draft is never deleted, and a

name with "%" is written whole like any other.

• --result is a .json file outside the Source and the settings; its draft is the run's own.
• cleanup_project.cmd refuses a folder that is a link and never walks through one.
• A lossless archive keeps the bits or refuses: x264 lossless turns down a 12-bit, RGB or alpha source (FFV1 keeps it),

float PCM is copied instead of going to FLAC.

• A run with a failed file is a failure, a run stopped before its first file is a stop; STOP ends a child that prints

nothing, together with what it started.

• Two sources of one stem write two files (take.m4a, take_wav.m4a).
• CUT takes a Source of one file.
• The loudness report of sound in a video measures every track.
• A copy of big-endian PCM goes to MKA: WAV does not hold it.
• A download repeated at once counts nothing as written; what was there is listed as existing.
• x264 keeps the fields and their order of an interlaced source.

The environment. Python carries only what the engine needs — PyYAML, pytest, pip-tools (59 MB). The scripts and the installers run in the PowerShell 7 of the program. The builder menu (builder_main.cmd) and the console menus on FZF stay.
