There may be times when you're unable to import an FLV video file from a third-party source, such as Adobe Connect. You'll see this error message:
"FileName.flv" does not appear to be a supported video format. Please select a video from one of the supported formats.
FLV is a supported format, but you'll see the error above if your Articulate software is unable to determine the duration of the video. To correct it, just change the file extension from FLV to either AVI or MOV, then import it into your Articulate project.
