Fade in/out in VirtualDub - Help !!!!

Hi,

I`m having real difficulty in using/how to use the fade plugins in vd.

I have a clip which starts straight off and ends straight off and would like to smooth in from black to full picture ; then end the clip fading to black.

In theory , simple but it` not , at least to me.

I have tried the fadefx and fader plugins , but they don`t work . On the fade-in , this is just impossible - no fade at all .

Fading out is also a no go. Could it be that these plug-ins don`t work on wmv files ? i don`t know.

I`m just going nuts here !

Please help anyone .

Thanks. :(
