| Runs on | Windows 10 / 11, 64‑bit |
| Graphics | Direct3D 11 — anything from the last decade |
| Input | Any pen that speaks Windows Ink — Wacom, XP‑Pen, Huion, Surface Pen — with a Wintab fallback for older drivers; a mouse works, badly |
| Needs | Nothing installed. ffmpeg only for MP4 out and video in — audio, GIF, APNG and PNG are built in |
| Size | 1.7 MB download, 3 MB unpacked. Self‑contained, no redist |
| Add‑ons | Video import, the update check and the pose packs are separate zips that unpack into the same folder |
Windows may warn you the first time. The build is code‑signed, but SmartScreen wants a reputation as well as a signature, and a new certificate earns that one download at a time. If the blue panel shows, click More info, then Run anyway. If your antivirus is a loud one it may want the folder excluded too.
The main download stays small by leaving the optional parts out. Each plugin is its own small zip. Unzip it into the Douga folder, the one with douga.exe in it, restart, and the new menu items are there. Delete the files and they're gone.
Douga-VideoImport.zip adds File → Import → Video, for pulling footage in to rotoscope. Frames land on the active layer, fit to the canvas, sitting in the transform box ready to place. Decoding runs through the same ffmpeg the exporter uses.
Douga-UpdateCheck.zip adds Help → Check for Updates. This is the only part of Douga that touches the network, which is exactly why it's a separate download: without it the app opens no sockets at all. It asks the download page for a version string, tells you what came back, and that's the whole conversation.
Douga-Poses.zip puts Eadweard Muybridge's motion studies from the 1880s, public domain, on the File → Import → Pose shelf. It's the big one, 14 MB of photographs. A pack is just a folder of numbered images, so you can grow the shelf with your own reference.
Douga is free — every feature, for any use, personal or commercial. Exports from an unlicensed copy carry a small Douga mark; a license key removes it, and that is the only difference. Everything you make is yours either way, always. The full terms are short and readable, and the same text ships in the zip as EULA.txt. Questions: contact@douga.app.
