FFmpeg is used for exporting selected clips, DualCam composition, and audio auto-sync. It is not required for normal video playback.
Double-click INSTALL_FFMPEG_WINDOWS.bat, or click Install Automatically in Picklary.
Microsoft WinGet installs Gyan.FFmpeg.Essentials.
Use the official FFmpeg download page and select a Windows build. After extracting the package, select bin\ffmpeg.exe through Picklary's Select Manually option.
Restart Picklary or click Check Installation. Export is ready when the processing status changes to a green ready message.
