FAQ

Questions, answered

Is SynFrame really free?

Yes. SynFrame is free while it's in alpha, with no account, no watermark and no time limit.

Which browser should I use?

Chrome or Edge on a recent computer give the best results. SynFrame uses your graphics card through WebGPU, and falls back to WebGL when WebGPU isn't available.

Are my videos uploaded anywhere?

No. The online version opens files straight from your computer and edits them in the browser. Nothing is sent to Syntera Labs.

Which files can I edit?

Common camera and phone video, including H.264 and HEVC MP4 and MOV files, ProRes, AV1, VP9 and DNx, plus images and WAV, AAC and Opus audio.

Should I use the online version or download it?

Start online, it's instant. Download the Mac or Windows app for long projects, offline work and the fastest exports.

What does alpha mean?

SynFrame is new and improving every week. Save your project often, and keep a copy of important footage.
