StudioFF v0.40

Tested with FaceFusion v4 commit a24893c (2026-10-19). Go to StudioFF's FaceFusion settings and press Use Tested Version for best compatibility.

StudioFF is a desktop app for the FaceFusion v4 face swapper. Not made or endorsed by the FaceFusion team.

New since v0.30

• System monitor in the title bar: graphics card, video memory, processor and memory use, once a second. Each reading has a bar that goes from green to orange to red as it fills. It can be turned off in Setup
• Setup shows whether your FaceFusion is the version StudioFF was tested with, and can switch to it, to the latest version, or back
• Batch lets you pick the frame each video previews on, and remembers it
• Batch outputs you remove stay removed after a restart
• Copy Settings from Studio asks before replacing settings that differ
• Stopping a preview keeps the models loaded, so the next preview starts faster
• Studio's left column scrolls instead of squashing in a short window
• Settings are read again if another program holds the file for a moment, and are never saved over a file that couldn't be read
• App data now lives in %APPDATA%\StudioFF. It moves there on its own the first time you start this version
