Frequently Asked Questions
Can I use Synfig professionally for commercial projects?
Yes, Synfig has been used by professional animation studios for commercial productions. The open-source license allows commercial use. However, support and documentation resources are more limited than commercial software.
What are the system requirements for running Synfig?
Minimum: 2GB RAM, dual-core 2GHz CPU, 500MB disk space. Recommended: 4GB+ RAM, quad-core processor, dedicated graphics card with 1GB VRAM. Linux requires GTK+ 3.0 development libraries.
Does Synfig support importing from other animation software?
Synfig can import SVG files, image sequences, audio files, and video. Direct project import from Harmony or other software is not supported, but assets can be exported as image sequences.
What export formats does Synfig support?
Synfig exports to image sequences, video via FFmpeg, Lottie JSON for web animation, SIF (native format), and SVG vector files. Audio must be added separately in post-production.
Is there a portable version of Synfig Studio?
Yes, a portable Windows version is available (114MB) from PortableApps.com. This requires no installation and can run from USB drives. macOS requires standard installation to Applications folder.
How does Synfig's bone rigging compare to Harmony?
Synfig provides solid skeleton-based rigging suitable for character animation. Harmony's professional rigging offers more advanced deformers and master controllers. Synfig is excellent for basic to intermediate character rigging.
