Good codec

[baly]

Hi all,

Sorry if I am not in the right place but I thought since I will encode to DVD & BD afterwards to write it here..

I have created a 3' clip using ONLY HQ photos.
I want to know which of these two codecs is used for good quality export.
AJA Kona 10bitRGB OR Uncompressed 10bit 4:2:2?

I have tried to export the same clip with both codecs and I see a difference in whites, blacks and in general AJA Kona 10bitRGB seems to have higher contrast but closer to my original footage.

I know most will say that use the one that seems better but I would like to know what are the differences and which one is mainly used by the professionals.

Thank you.

No experience with AJA Kona but apparently it's uncompressed, so they're equal as far as quality, lossless.

Are you sure the differences you are seeing is not just a playback issue related to Luminance Levels?

maybe your player or vga don't show 16/235 range of yuv right.

They're all uncompressed. The codec isn't your issue. The way data is being handed into the codec or pulled out of it is the issue.

Thank you all.

The preview is via AJA SDI output on a JVC FullHD Professional monitor. And there is where I see all the differences.
VGA don't get in the way.

@Blue_MiSfit: What do you mean exactly? What can I do to check if this is really the issue?

And one last, what is the differences between AJA10bit & Uncompressed10bit?
They both are uncompressed but AJA's is @~222MB/s and the other @~222Mbit/s.

The AJA files are 8x larger than standard uncompressed?!
