is it not longer possibility to import a video in Camtasia 9 with a transparency (on a Windows system)? Camtasia supports the .mov format only with a h.264 codec, right? But die h.264 codec can ́t export a transparency. Transparency works only at .mov-fiels withe animation, png and ProRes444, but camtasia9 can ́t import that format under Windows.
What is a possibil workaround to import a video with transparency?
