Codec column contains filtered codec names used for file creation;
Avg Write Time (ms) column contains frame write times expressed in seconds;
File Size (KB) column contains AVI file sizes expressed in kB (base 10 unit as defined by SI);
If an x264vfw codec is installed in a system, example fails with an error -1074395992 File access denied, because it tries to create a file with a name containing one of restricted characters, namely "/". I understand that it's just an example and doesn't account for everything, but it already has name filtering in place and could easily filter all restricted characters.
