Frage von cmartis:
Hi,
I'm really sharp AF100 / 101 on the Panasonic in the next time comes out I would like your opinion on the HD SDI output which outputs bits in 422 in 8 ...
If I do buy a Nano flash that records in 10 bit 422, since then I have a big loss or not there would be worth the investment ...
Keyen If I want I know the 422 is better than 420, here's the big difference.
But when I change between 422 and 422 8bit 10bit has a disadvantage because when keying?
For example, natural images would be safe because not much difference ... I mean ...
MFG

Antwort von WoWu:
The reason for the 8-bit SDI s.der likely to be low data rate s.einem single-SDI output for 1080 to be
p50. An external recorder does not turn because, on the contrary, if you make the round trip 8-10-8 bit, you have the known artifacts in addition to your picture.
What is the disadvantage of keying is concerned, it always depends on the image content with what s.and Keyer you work .... And of course, synonymous to your needs.
Differences to exist in 4:2:0 mediocre material critical of all things already. Only 10 bit so synonymous have other advantages.
Antwort von cmartis:
OK, but where is the the 1080
50p here?
The camera makes the standard but not synonymous and not the Nano Flash ...
Antwort von WoWu:
This is indirectly through the slow setting (varible frame rate) into the game because 1080p50 in the standardization is not yet complete. In this respect, 1080p50 in an enlarged 25 Form already available and of course synonymous badarf a corresponding data rate, the single SDI no longer packed.
The camera creates the loose and just the codec, because it is one of the few codecs that can do at all.
But if I had the choice between 1080p25 and 1080p50 in 10 bits in 8 bit, I would vote even for the 50 images.
As for the Nano Flash, so the bottleneck is definitely not the hardware but the codec on it. The just can not 1080p50. But of course, synonymous again the interface.
