Render Artifact in YUV 10-BIT Apple Pro-Res
HI Everybody,
I was rendering a video clip, shot on XDCAM, edited and on-lined in FCP (with MAgic Bullet Looks).
The render settings were on High Precision YUV – which cause weird green and yellow semi transparent squares on the Final Render – not on all shot, but on the Night / Darker ones. When I rendered it again in 8-Bit YUV setting it was fine. Why is it not working in High Precision YUV?Any ideas???
Thanx.
Greetz,

Hi Sascha,
i guess may be your GPU.
I can not use MBL at 1080 with 10b.
If I want 1080 it must be 8b.
Same happens with the fXplugs.
I get a warning: Your GPU..

Hi Rafael,
yes, you are totally right. I remember – I had the same issue with fxPlugs and other third party plug ins.
Might be the case now. I work on a 17inch MacBook Pro 2,5Ghz with 4GB RAM.
Well, I rendered it now in YUV 8-Bit and it looks fine. Anyway the MAster has to go on Beta SP – that is the highest quality they accept at the Israeli MTV anyway – so it won’t matter so much.
I see you post quiet a bit – and very helpful stuff – thanx.
Is there a site I can watch things from you?
If you are interested here you can find some of my film and theatre work:

GPU?
That is really interesting theory!
I get those artifacts every now and then I had no idea what was the reason until now. WOW!
But that GPU also sounds REALLY strange to me. Isn´t it all just about mathematics? Do I now have tho think that my GPU gets some mathematics wrong like 1 + 1 = 3 and some other GPU gets it like 1 + 1 = 2 ?!?!?
So in theory, if we give same clips with same efects to different Macs we will get different looks????? It can not be so!Sorry folks, got a bit theoretical…

Well, I am not too smart when it comes to what’s under the hood of my car, but I just take a guess, that certain graphic cards are not strong enough for complicate effects in 10-Bit – it has to do with it, cause when I switched back to 8-Bit, everything was fine.

Hi sascha,
I sow your video “dancing in the border’. Great.
Really powerful look. According to the place 🙂
I will watch more of your clips.The kind of videos I make there are no much to show to friends.
Are mostly educational videos and related with development, education agriculture, etc.
Some time I make little clips for fun:You can find my mail in my profile.
Cheers,

Yes, I got that, but this is just mathematic, so one card can only make it faster than an other. Isn´t it like processors, G4 can do exectly same mathematics as Nehalem, only difference is that Nehalem is waaay faster?
Sorry, I am difficult personality… -
not exactly – i just changed from my G4 and certain things could bot be rendered with HD material due to limits of my Graphics Ccard….and now I can.

Wow, AMAZING images. Sony EX-1 – great camera. You shot this footage? Chapeau.
Some of it looks really breathtaking – in what did you do the grading and color corrections?
And with what apps did you work?Sascha

Hi Sascha,
Thanks for watching the clips.
I’m very bad cameraman, but in this place is almost impossible make bad pictures.
The EX- makes really good image.
I’ve just bought the nano-Flash and you really see the difference of compressing the picture at 100 or 160 Mbps instead of 36.
I used to work a lot with MB, but I stopped because the problems we have been talking about.
This have pushed me to Color, what is OK because that forced me to learn “classic CC”.
But I’ll be back to MBL when I’ll buy my next Mac.
Many people think of MBL like a not much professional tool because because it comes with many presets
To get a real control of MBL you need the same knowledge of color grading than needed to run Color or a DaVinci.
Cheers,

HI Rafael,
what is a Nano-Flash – just in case, I lose all my Nerd-Credits with that question – I am sorry.
Never heard of that!Sascha
