I have a Sony HDD based camcorder that records in MPEG2-PS and AC3 audio. I also have a copy of Vegas Pro 8 which prompted me to install AC3Filter as there is no native support in XP. Everything worked fine with camcorder video editing.
I recently bought a TV with USB record function and this creates files in the same format as the Camcorder, all was fine until I was given an XVid with AC3 sound [thanks to a friend who provided it after I failed to record a program I wanted to watch]. I tried to use Sony Vegas to create an MPEG file that will play on the TV however Sony Vegas will not recognise the AC3 audio [nor will Vdub-MP3] in the XVid.
This prompted me to get a copy of GSPOT and the ‘list codecs and filters’ function tells me that;
ACM Base msacm.ac3filter ** Missing file: ac3filter.acm
I have found 2 copies of the file ac3filter.acm, one is in “Program Files\AC3Filter” the other in “Windows\SYSTEM32”
I have also created some other XVid and DivX files with AC3 audio using Auto Gordian Knot and Sony Vegas will not recognise the audio in those files either.
What have I done wrong?
