I have been editing an dvpal standard avi file for over 2 weeks and exporting ok. I wanted to make a different cut of the avi file and today i find when importing it into premiere it says - type of file not supported, maybe code required.??? whats that all about, it the same file as the other day. Its either supported or it isnt. Now im really confused.
If it is a DV-AVI, there should be no issues, unless something has changed on your system. The MS DV/DVC CODEC should be installed in your OS, unless some program overwrote, replaced, or deleted it.
Can you download, and install the great, free utility, G-SPOT, and run your DV-AVI though it? Please post a screen-cap of the G-Spot screen, so we can see everything it reports.
Something has changed, either with the file, or with your system. G-Spot will tell you all about both - file and system.
