Which ProRes encoder in Voukoder?

  • FFmpeg comes with 'prores', 'prores_ks' (fka 'prores_kostya') and 'prores_aw'. Only prores_ks supports alpha channels (and the 444 & 4444 colourspaces) and has a few other flags you can set for advanced render settings. It's that's what I've used in the past for prores work. Which flavour of prores encoder is used in Voukoder?
