Blackmagic 10Bit not Realtime

[Chris Borjis]

I’ve heard a lot of people having this, but 99% of the time
they rendered the video as 720×480 it MUST be 720×486.

one quick fix that would be faster than re-rendering if you have a gazillion layers in after effects, would be to download and convert with mpeg streamclip.

just open it and export it as 486 and it will do a great job of quickly converting it so it will play in realtime.

in the meantime i checked out that fc on the mac pro does not even accept clips that have been created on the same machine. only captured material is “realtime-capable”.

i did it this kind of work so many times before and hat no problems at all…

i thought that something must have happended after one of the recent updates. so i asked at this forum.

preferences, quicktime, decklink-drivers?

thanks a lot anyway!

something is terribly wrong if you cannot render out 8 or 10-bit uncompressed and have it play real time in fcp with black magic hardware.

it truly is…

anyone experiences with blackmagic 10bit RGB realtime-editing with final cut???

Do you have the 10 bit RGB codec as your selected codec? You aren’t using the Apple 10 bit codec? That could be your problem.

[Alexander Feichter]

in the output module of ae i can select Blackmagic 10 Bit – in the fc-export it is “called” (apple?) Uncompressed 10-bit.
i never really understood when the apple and when the blackmagic codec comes in action. are they not the same?

what i would like to do is to edit footage from a highspeed camera that is available as tiff-sequences. i did that in the past with blackmagic 10 bit, but due to weird fc-behaviour it does not work anymore. time is running out…

so i thought about editing in 10 bit rgb – but ALL the REALTIME EFFECTS are disabled then. on a mac pro???

QUESTION: anyone editing in 10 bit rgb?

[Aaron Neitz]

I don’t think you get ANY realtime effects using a RGB codec. you need to be in YUV to get that.

Take your tiff into AE. Put into a composistion. Comp settings need to be set to D1 (720×486 with .9 pixel aspect ratio). Make Movie as 29.97 fps Apple Uncompressed 10 Bit. Make sure FCP has the timeline settings for Uncompressed 10 bit NTSC. It should work just fine. I think you’re missing something along the way – triple check all the settings.

[Jeremy Garchow]

Yep, that was going to be my response as well. What Charlie says.

AAAAARRRGH!!!!

i’ve just begun to do a series of screengrabs to show my settings and the i saw:
575 instead of 576 pixels width on the rendered clips! i’ve overseen it all the time and wondered and wondered…
those two numbers look so damn similar!

i feel better now 🙂

sorry for stressing you all… and thanks a lot!
