BB FlashBack desktop activity recording software supports export to AVI as one of the main file types for export, which can be done easily with the default export or batch export function. You can choose from several types of codecs and adjust the compression ratio, but compared to more modern video formats the settings are bit bare-bones.
If you do not own BB FlashBack, you can download the 10-days trial of either the Pro or Express version, but the export will leave watermark on the video unless you purchase the software.
As far as we know, no other software can be otherwise used for fbr to avi conversion.
