hi. na kakom jazyke dolzny byt video? and do you use narrator? or must be rented?
i can do a pro video for your software, if you not just re-listing tutorial offer.
Be highly and quality compressed, optimized in time with "text layer" and saved on mp4 format.
even HD video can be downsized to few hundred megabytes and be over 20 min ~aprox.
so if you are interested - contact me and maybe i can help you
