Version 9 and JPEG2000

Hello,

I would like to know if Blackmagic will implement JPEG2000 output (in XYZ DCI color space) ? It would be a very useful tool because most of the films I graded during this last year are for DCP, it means that I used DPX only to convert them in Jpeg2000. Anyone else thinks that would be a good option ?

You know how long it takes to render to XYZ converted JPG2000, right ?
Around 9 hours..
I prefer to leave the DCP encoding to the specialists and provide them with something also suited for REC709 projection, internet and data streams ready for a regrade.

Hello,

I know... I make DCP with easyDCP creator + since two years. It's not so long to render in JPEG2000, that's why I was thinking about add this feature in DaVinci.

[Robin Erard] " It's not so long to render in JPEG2000"

I am curious about your statement here... could you give us an idea of rendering time with the spec. of your system? I have never done a DCP myself before, but I just had one done recently and I understand the lab we used have a render farm to speed up the process. I have read a single fast computer system could process 2K film into JPEG2000 @ 1 frame/second. Which is still 36 hours of rendering time for a 90 min. film!

If it is the case I am not sure I see the advantage to use Resolve for that purpose. In any case wouldn't it make more sense to keep an uncompressed output master from DaVinci for keeping the delivery choices open without taxing Resolve?


Thanks,

Hello,

I made a test for you this morning :

INPUT:
DPX 1920x1080 REC709
5760 frames
at 24fps = 4min

OUTPUT :
JPEG2000 XYZ

8'30'' to do the job, then about twice the duration.

My computer : MacPro 2x2.26GHz Quad-Core Intel Xeon
16Go 1066 MHz DDR3

The process for the last feature I encoded (1h30 - 1.85 1998x1080) was less than 3h30 hours.

Thank you Robin for your test and the information: I guess I was quite off base with my timing :-)
Good to know! I am wondering if EasyDCP creator is faster than some other solutions out there?

Merci,
