I have just installed Vegas 2.0h.
I only get to render to WM8. I already had this installing the media encoder 7.1.
I do not see the new options to v8 as double pass rendering.
yes it appears that the dual-pass rendering was not included. looks like we're stuck rendering to the DV codec and then recompressing to WMV using the WM8 encoder utility for now...
No this has not been implemented, the WM 7.1 SDK that was released did not include support for 2 pass encoding. This was the SDK our WM8 support was based off.
MS really confused the numbering on these releases. The v 7.1 SDK included the v8 codecs. Then they put out a beta of v9 SDK that also used the v8 codecs but included the 2 pass and synchronous reading. We are researching the feasibility of implementing the 2 pass encoding at this moment.
