How to work with it: the workbench, the order of running an operation, trimming with the player, the pages, the reports.
The Order of Work
- Choose the source and the output folder.
- Open the page you need.
- Pick a profile.
- Change only what needs changing.
- Press
Command— see exactly what will go to FFmpeg. - Run the first file.
- Run the batch.
The profile sets a ready base; the fields below override it selectively. Checkboxes never enable hidden actions the profile did not set.
Steps 5 and 6 are not skipped on a new operation. A wrong parameter costs seconds on one file and an hour on a folder.
The Workbench
The top row sets two paths for every page:
| button | what it does |
|---|---|
| Source | the folder with the originals |
| Add file… | a single file as the source |
| Target | the output folder |
| Reset | restore the project Source\ and Transcoded\, touching no files |
| Delete | clear the current source and target after confirmation |
| List | print the names of the current source files to the terminal |
Path fields remember history; a pinned path moves to the top. Clearing requires confirmation.
The source is walked recursively and the output mirrors its structure:
Target\<operation>\<profile>\<as in source>\<filename>.<ext>
Source\Day1\clip.mov and Source\Day2\clip.mov do not collapse into one flat folder and fight over a name.
Trimming: the Player and Its Keys
Cut points are found in the mpv player — opened by a button in the section — and carried into the fields by Take A and B. The keys work in the player window, not in the program panel.
The dozen keys that do the whole job:
| key | what it does |
|---|---|
Space | play or pause |
, . | step exactly one frame back or forward |
← → | seek 5 seconds |
Shift+← Shift+→ | exactly one second back or forward |
Shift+↓ Shift+↑ | exactly five seconds |
↓ ↑ | one minute back or forward |
Home | to the start of the file |
l | set point A; press again for B; the piece between them loops |
Ctrl+l | clear A and B |
b | play backwards |
n | return to playing forwards |
[ ] | 10% slower or faster — at 0.25 every syllable is audible |
Backspace | back to normal speed |
s | a frame grab next to the source file |
l is the cut: set A and B, listen to the loop, and if a point is wrong nudge it with , and . and press l again.
The difference between ← and Shift+← matters. An ordinary seek jumps five seconds and shows the nearest frame; Shift is exact, precisely one second, and lands on the frame. Finding a cut point needs the second one.
b and n were added by this build: in stock mpv b is debanding, overridden here.
The full list — all 197 bindings with their player commands — is in tools\MPV_HOTKEYS_RU.md. It was taken from the player itself through input-bindings, not copied from a web page.
Trimming in detail — the working cycle, the three actions, accuracy, refusals — is in tools\TRIM_RU.md; what is compatible with what when cutting is in tools\TRIM_MATRIX_RU.md. Both are Russian.
The Pages
| page | about | in detail |
|---|---|---|
| Download | a link or a list, format profiles, resolution, subtitles, threads | tools\YOUTUBE_DOWNLOAD_RU.md |
| Audio streams | extraction, resampling, loudness, packaging; audio into video without re-encoding the picture | tools\AUDIO_WORKFLOWS_RU.md |
| Trimming | frame-accurate and keyframe cuts, marks remembered per file | tools\TRIM_RU.md |
| Remux, frame rate, colour | container changes, frame rate, lookup tables, HDR to SDR | tools\REMUX_FPS_LUT_RU.md |
| Archive, editing, storage, delivery | lossless FFV1 and x264, ProRes and DNxHR, x264/x265/AV1, upload profiles | tools\ENCODING_PIPELINES_RU.md |
| Diagnostics | what hardware is present, what it can do, profile checks | tools\HARDWARE_DIAGNOSTICS_RU.md |
Section documents are Russian only.
Hardware
The program can choose between the NVIDIA, Intel, and AMD hardware paths, separate AV1 encoder and decoder, and the plain processor.
Run "Hardware Capabilities" before the first run on a new machine. The result is cached and hardware profiles are checked against it. A missing path is a normal answer, not a fault: it means the driver or the hardware is absent.
Terminal and Reports
On the right: operation status, progress, the log, a Command button for a dry run, links to logs, reports, and settings, a terminal expander, and a manual command line with history.
Every operation writes batch_report.md and .json. Audio adds audio_report.md and .json: the source stream, input parameters, processing mode, loudness, output path.
The workbench, the path cache, the terminal, and the reports are covered in tools\WORKSPACE_REPORTS_TERMINAL_RU.md.
Rules for Safe Work
- A new operation:
Commandfirst, then the run. - A large folder: the first file first.
- Do not enable overwriting unless you are sure of the target folder.
- A hardware path: check the hardware capabilities first.
- A colour table: look at which
.cubeis selected. - A download batch: check the list of links first.
- Cleanup: look carefully at the selected folders.
- Never run two operations at once in one window.
Checks After Changes
runtime\python.exe -m py_compile system_core\ui_nicegui\app.py system_core\services\media_service.py Scripts\Common\script_runner.py
runtime\python.exe system_core\ui_nicegui\app.py --smoke
What is actually run before a release: the checklist (Russian).
Technical Reference
Running
launcher_gui.cmd
If the environment is not built:
builder_main.cmd
The window opens at http://127.0.0.1:8080/.
Tooltips
They appear after 1500 ms, hide in 100 ms, background RGB(23, 33, 43). If a field is unclear, hold the cursor on it for about a second and a half.
Tooltips cover audio modes, stream selection, loudness, the resampler, hardware encoding, remux pairs, colour tables, and operations with side effects. File extensions and obvious buttons such as "Back" and "Run" are not duplicated by them.
For the outermost buttons in a group the tooltip aligns to the edge so long text is not clipped.
Workbench Naming
One shared vocabulary across all Audion projects. In Russian: Источник, Добавить файл…, Назначение, Сбросить, Удалить, Список. The words Destination, Clear, «Цель», and «Очистить» are not used for these controls.
