We thought its time to get some input from you guys about an upcoming feature, namely adding 4k as a download option for our movies. All scenes shot since Sept. 2014 are shot in full 4k so we will retroactively encode them and add them.
All that’s left to nail down is the bitrate.
Now that brings us to a bit of a scam the adult industry has been pulling on customers. It started 10 years ago with “HD movies” and continues today with “4k movies”. It seems customers are being deluded into believing marketing hype when they should really be asking: what bitrate is the movie encoded in? Rather than solely looking at resolution.
We have done some research and found many of our competitors encode their 4k movies at about 10-15 Mbit. In our humble opinion that’s grossly insufficient — actually that’s the bitrate we apply to our regular 1080p HD movies. You get the picture? If I upscale the image by a factor of 4 (two times two) but leave the bitrate unchanged then image quality is going to take a nosedive.
So here’s a one minute sample of what we’re looking at right now, after a lot of back and forth trying to find a compromise between image quality and file size:
3840×2160 @ 45 mbit VBR, approx. 375 MB per minute. A 45 minute scene will clock in at a whopping 16.8 GB.
