Hi there! Just rendered out a project with an alpha channel. It's just some white text, and no background. When I overlay the rendered output over a color clip, I can see that the transparency rendered correctly. However, I have proxies turned on by default, and the proxy that was generated for this clip with transparency lacked the alpha channel, and had a black background. First I thought the alpa channel did not render correctly, but once I turned off proxies, I could see that the alpha rendering did indeed work correctly. The proxy generator needs to be able to figure out if a source clip has an alpha channel, and somehow be able to render a proxy clip with alpha channel support.
