The best choice to clip a wmv without re-encoding is Windows Media File Editor. The alternative is Boilsoft Video Splitter.
WMFE is very limited but effective.
As with any compressed video the In and Out points can not be place whererever you want (keyframes and so on). You must let WMFE fix the points.
To mark In and Out points follow this procedure:
- enter an approximate time. for example: 0: 24: 05: 150
- press Play,
- at the desire point , press Pause, press Mark In.
- press Play again, Pause again.
Repeat this steps to Mark Out.
WMFE will freeze if you donÂ´t press Play before and after marking In/out .
I thank you all, specially Chad976zip7
