Feature that would be great (and profitable) for video sellers, would be to have a file transcoder that converts 4K files to HD. This way one could offer ‘premium’ 4K at say $179 and standard ‘HD’ at $79. It doubles options for customers and increases likelihood of a sale. Right now 95% of my sales on stock sites like P5, SStock and Adobe are HD, even when the source file is 4K.
