Virtualdub not reading avi's

I can open certain avi’s with vdub.It wont let me open avi’s created with ulead.Says i need a vfw codec.I downloaded these.Still no good.What now. Are there different avi’s?

AVI is essentially a wrapper around a combined audio and video stream. Included in the file is what type it is so a media player can make sure the decoder is loaded and then let it decode the stream and send it back to the application.
To see what the possibilities are, load a AVI into vdub and go to Video->Compression and see how many you have loaded on your machine :slight_smile:

Also check the AVI with GSPOT and it will tell what codec thats needed and if its installed.
