I will be very interested to see how EditShare will handle the open source aspect of Lightworks, compared to their commercial version. I'm specifically thinking about formats/codecs here. For example DPX is a format I and companies I work for use a lot, and that is only available in the "Pro" version. What will happen if community implements support for DPX (and other formats) currently only offered in the paid version? I understand that formats like R3D requires a commercial license for redistribution, and therefore only available in the paid version, but I think it is silly that DPX - which is an open standard - is excluded from the free/open source version, as well as codecs that can potentially be covered by ffmpeg.
So again, will be interesting to see how "open source" EditShare allows it to be...
PS: There is no doubt that Lightworks isn't open source as it stands now, and while their intentions might be good, I don't like when companies use the term "Open Source" as a PR stunt, and worse yet if it turns out to be Microsoft's "Shared Source" (look but don't touch).
