What format?

[anGGa]

Hi,

I wanted to know what for dvd-rip avi format the movie I downloaded, so I opened it with virtualdub and this error occured;

Coulddnt locate decrompessor for format MPG4 (Microsoft High-Speed MPEG4)

VirtualDub requiers a Video for Windows (VFW) compatible codec to decompress video. DirecShow codecs, such as those used by Windows media player, are not suitable.

Where and how do I install this VFW? And with which codec was this movie encoded?

Some info's please!

If you want to install the Microsoft MPEG4 codecs (& other legacy codecs) then visit

http://www.microsoft.com/downloads/release.asp?ReleaseID=31921&area=search&ordinal=2


or just download & install

http://download.microsoft.com/download/winmediatech40/Install/8.0/WIN98Me/EN-US/wmpcdcs8.exe

(Watch out for word wrap with the links)

Note that MPEG4 codecs 1, 2 & 3 will be installed NOT any DivX hacks.

Well is it ok to mix both codecs; MPEG4 and DIVX?
Thanks..

I have both DivX (V4) and MS's MPEG4 codecs installed on my pc and they both work OK.

almost note the MS Mpeg codecs are locked and cannot be used to compress AVI

Microsoft's MPEG4 codecs versions 1 and 2 are both capable of encoding as well as decoding.
It's the version 3 codec that's now 'locked' so it can decode but not encode.
Version 3 was originally capable of encoding but Microsoft decided to 'lock' it to decoding only.
The old Version 3 can be found if you've got the patience to find it on the web.
That's the situation at present i believe.

(Currently using MPEG4 V2 for VHS captures myself).
