"frame accurate" wmv9 editor, is it possible?

[hyfans]

hi there,

i've got some 5Mbps wmv9 files on hands.

so i want to do some nonlinear editing on them.

windows media file editor which comes with Windows Media Encoder9 is the only tools i use now. the only problem is i can't do file joining in this tool, only simple cutting is possible, i think.


also tried the asftools, joining works but the output file
has serious sync problems on the "editing point" of the input files.


avs editing of wmv also have sync problems with it. i believe that's because seperate audio/video file processing of avs.

windows movie maker need recompressing when output, also i can't use customized profile.

so is it possible to do nonlinear editing without quality loss?

I'm not aware of any tools like that. The WM Format SDK certainly allows it, but nobody has really leveraged it thus far.
