When you produce an art piece, video etc. chances are it may require more than one skill set, you probably expert in few areas but most of the time you gonna need free high quality contents.
It’s very difficult to Find a reliable high quality resource for images, videos, stock footages etc on Internet, it’s somewhere in the crowd of low quality but free and high quality but pricey contents. If you are rich you can buy high quality content from Internet, there are lots of services available out there but if you are running on a low budget, it seems like a daunting task.
