I found a VERY simple fix over google.
The problem is rather famous. While using Vegas 9.0d-e (or even more recent versions), you receive the error message "unrecognised frame format, please install the latest version of fraps" upon importing AVI-files recorded with fraps.
Other symptoms of this problem are:
- a ridiculously slow booting vegas
- vegas taking very long to import AVI files (as opposed to instant, which it should do)
- long waiting times upon opening projects.
- rendering errors (black frames) and crashes upon rendering
Here's the fix:
you need to acquire the file "aviplug.dll" located in .../Vegas/FileIO Plug-Ins/aviplug/ from a vegas
PRIOR to vegas 9.0d. it must be vegas 9.0c or older. now use that older .dll you got to replace the one in your vegas version and your problems will be gone.
works for me in 9.0e and has been reported to work in lots of others. just make a backup and test it.
