[kdenlive] [Bug 514312] .mov files without transparency

I can imagine other applications working the same way. So, pay close attention to the render or export settings in Friction and choose a format that supports an alpha channel like ProRes or VP8 and VP9. The mlt format must be set to rgba, pixel format to bgra. I am closing this bug report as RESOLVED-NOTABUG -- You are receiving this mail because: You are watching all bug changes.

It pains me to say that the clip does NOT have transparency. I have attached two screenshots: one with a color clip that has been scaled down to show the background in the clip monitor, and the other with the clip also scaled down a little. I have set the Clip Monitor background to Checkerboard to see where there is transparency. -- You are receiving this mail because: You are watching all bug changes.
