Davinci Resolve 12.5 Jpeg2000 encoding is very slow

PostSun Jul 24, 2016 12:32 pm

Running Davinci Resolve 12.5 in MacPro Cylinder with Dual AMD D500 Graphics Card.

When I try render JPEG 2000 file format system encodes in 0.5 to 1 frames per second whereas When I try to encode Easy DCP DCP Package its almost realtime or half the realtime.

Am i missing something here.

Can Blackmagic show some light on it.

JPEG 2000 enconding IS slower than most of other codecs. But it is an overall better compression than the most (if not all).

Because easyDCP is very good GPU implementation, where Resolve is some basic one. JPEG2000 is very complex so you end up with such a big speed differences. JPEG2000 has good efficiency, but not crazy good and in the same time is crazy complex and slow, so it's overall "value" is not that great. Always requires very good implementation (in most case specialised hardware chip) which is expensive.

For realtime encoding of JPEG2000 can Blackmagic show some light on which Intel processor is capable of this.

For 4K probably none with BM slow code. You need easyDCP with good GPU.
