In Comprimato, we accelerated the JPEG2000 codec on the GPU and together with the fastest GPUs from NVIDIA (Quadro GP100 and Nvidia Tesla P100) we are offering real time 8K encoding/decoding to everyone.
I prepared three scenarios which I believe can be close to further 8K video recommendations:
- 8K Broadcast – Broadcasters use 422, 10bit, 60 FPS profile with bit rate around 100 Mb/s for HD and 400 Mb/s for 4K. Hence for 8K it will be probably around 1600 Mb/s.
- 8K Digital Cinema – DCI profile defines 444, 12bit, 24 FPS video profile with bit rate 250 Mb/s for both HD and 4K videos. However, I believe that for the next generation 8K digital cinema, it will go up at least to 60 FPS and 4000 Mb/s.
- 8K Archiving – For archiving purposes a lossless compression is used which returns mathematically (exactly) the same image. In my tests, I used 444, 12bit profile.
As a test file we used 8K footage from RED camera (8192×3456). Results for Comprimato JPEG2000 codec on NVIDIA Quadro GP100 are shown below:
Comprimato JPEG2000 codec is able to deliver faster than real time 8K 60p decoding on a single NVIDIA Quadro GP100 card and 8K 60p encoding in multi-GPU environment.
If you doubt this incredible speed due to the speed of the PCI-e bus, then please look at my previous blog.
