Windows notes
SmartScreen, GPU, and 64-bit.
DropForge is an unsigned portable exe until a code-signing certificate is added. SmartScreen will warn. More info → Run anyway is the expected path for a new publisher.
Encoder: Auto uses NVIDIA NVENC, AMD AMF or Intel QSV when FFmpeg lists the hardware. Otherwise libx264 / libx265 on CPU.
Needs Windows 10 or 11, 64-bit. GUI is about 50 MB; FFmpeg is ~80 MB on first run.
