Install script: double-click Install-AVPrep2.cmd to download AVPrep2, unzip it to your account, and add Start menu and desktop shortcuts. It needs no administrator rights and removes nothing. Add -Setup in PowerShell to run the Setup program instead.

Install

1. Download AVPrep2-Setup-0.1.0.exe and open it.
2. Windows SmartScreen will probably say it protected your PC, because the installer isn't code-signed. Click More info, then Run anyway.
3. Click through the installer. It installs for your Windows account only, in %LOCALAPPDATA%\Programs\AVPrep2, and needs no administrator rights.
4. Start it from the Start menu or the desktop shortcut.

Updating: close AVPrep2, then run the newer installer over the old copy. Your settings, presets and autosaves stay where they are.

Removing: Windows Settings, Apps, AVPrep2, Uninstall (or the Uninstall shortcut in its Start menu folder). The program goes; your settings, presets and autosaves are left in the data folder so nothing you made disappears by accident.

Portable copy instead

The zip runs without installing, from any folder you can write to, including a USB stick. Extract the whole zip, then double-click AVPrep2.exe. Keep the folder together; settings live in the data folder beside the program and travel with it. If Windows blocks the extracted files, open PowerShell in that folder and run Get-ChildItem -Recurse | Unblock-File.

What it needs

• Windows 10 or 11, 64-bit.
• About 750 MB of disk space, plus room for your exports.
• Nothing else. FFmpeg, FFprobe, the Whisper speech engine and its English model are included. No account, no internet connection, nothing is uploaded.

What it does

• Clip: set In and Out (I and O keys), preview with Space, export to the queue with Ctrl+E.
• Composite: put photos and video segments in order with durations and transitions, add a voice track and an optional music bed.
• Captions: import SRT or VTT, or transcribe on your computer with Whisper, then edit text and timing and export or burn them in.
• Metadata: Strip All Metadata is on by default; anything you type is written after the strip, and finished jobs show what tags remain.
• Target size: give it a file size and it works back to the bitrate, then shows actual against requested and offers a retry if it runs over.
• Platform presets, editable in plain fields, and MP4, M4A and other audio formats.

Quick start

1. Open Media, or drop files anywhere in the window. Pick Audio or Video.
2. Choose Clip and set In and Out.
3. Choose an output folder and export settings, then Ctrl+E. Finished files never replace an existing one; the name gets a number instead.
