Methods for Generate Still Video filter in qedit.dll

Has anyone cracked the "Generate Still Video" methods? It appears this is the default source filter when using RenderFile for bmp, jpg or other still image format. I don't understand why the methods for this filter are not published. If someone has data on this filter please pass it on. Thanks.

Talked with a couple of Microsoft engineers today. Turns out not all of the GSV interface is exposed through COM.
