"Jaded cynics that we are, we don't say 'wow' much at DPReview, but the Z9 is a camera that has impressed all of us. Even before we'd had one in our hands, the Z9's specs seemed like a wishlist, comprised of all the features that a professional photographer might want. We've described the Z9 as the most 'DSLR-like' of any mirrorless camera that we've ever seen, largely thanks to its immersive, black-out free electronic viewfinder, but that doesn't mean that it feels like old technology. While it's DSLR-like in terms of size and weight, the Z9 eclipses the likes of the D5 and D6 when it comes to both features and performance."

Já tinha algumas dessas informações nas páginas 8 e 10 deste tópico. Mas esse link do Nikon Rumors acrescenta algumas informações sobre vídeo.

Sobre os arquivos RAW (NEF) da Z9: 14 bit:
- lossless (compressão sem perdas)
- compressão high-efficiency*
- compressão high-efficiency

Não existe a opção de RAW 12 bits.

Thom Hogam já fez uma ressalva com relação a isso:fonte:
https://www.zsystemuser.com/z-mount-cameras/z-camera-articles/the-unanswered-z9-questions.html

Segundo Hogam, temos 2 possibilidades:
1. Os novos formatos são licenciados pela IntoPIX e são TICO RAW
2. São algum tipo de formato HEIF (High Efficiency Image File)


Informações sobre o TICO RAW:
Bom, mas isso acima pode ser considerado bla bla bla de marketing.

Vamos a alguns detalhes técnicos:

Imagem/video
Color format
 - CFA  (color-filter-array):RAW data ,  Bayer data (RGGB, RCCB, ...) (optional monochrome and 4:2:2 mode)
 - Bit depth:  8 / 10 / 12 / 16 bits sensors
 - Resolution:  Any up to 200 Mpixels ( 50.000x40.000 pixels)
  -Frame rates: Any (depending on ASIC / FPGA or  CPU/GPU processor configuration)

Processamento
 -Quality: Mathematically lossless / Near-lossless / visually lossless / lossy down to 1 bit per pixel (bpp)
 - Rate control: Constant Bit Rate (CBR) operation (or Constant Quality mode), adjustable from ~2:1 down to 20:1  (0,5bpp)
-  Latency:  (Sub-) intra-frame: down to 0.1 millisecond
  - Proxy option: Downscaler in decoder for fast analysis, raw proxy viewing and editing

Com as informações acima é possível especular que (minha opinião):
- High Efficiency+ seja Near-lossless
- High Efficiency seja visually lossless ou lossy

Tamanho dos arquivos:
55MB Lossless raw
33MB High Efficiency Raw Star
22MB High Efficiency Raw
24MB JPEG Large Fine.

E porque isso tudo acima é importante?

Já temos uma discussão gigantesca pela internet sobre a capacidade do buffer da Z9. Aqui mesmo nesse tópico já tem alguns vídeos mostrando um pouco dessa questão. Além disso o desempenho é diferente entre marcas e modelos de cartão CFexpress tipo B.

De acordo com a documentação da Nikon temos:fonte:
https://www.nikonusa.com/en/nikon-products/product/mirrorless-cameras/z-9.html#tab-ProductDetail-ProductTabs-Overview

O primeiro teste que o Matt Grande fez, veja aqui:
https://forum.mundofotografico.com.br/index.php/topic,140644.msg1472466.html#msg1472466

Ele conseguiu 1899 fotos usando o formato High Efficiency. Com o High Efficiency* foram 550 no buffer.

Depois ele fez um outro testes, mais completo, envolvendo os 3 formatos e diferentes cartões. Veja aqui:
https://forum.mundofotografico.com.br/index.php/topic,140644.msg1472605.html#msg1472605

Mas o melhor teste, na minha opinião, foi o do Ricci. Veja aqui:
https://forum.mundofotografico.com.br/index.php/topic,140644.msg1472518.html#msg1472518

teste com 20 FPS, notem a diferença nos resultados.
Com o cartão CFexpress Delkin Black 1440 MB/s
loss-less: 81
High+: 1100+
High: 3000+

Lexar 1000 MB/s
loss-less: 61
High+: 182
High: 1000+

Bom, coloco mais informações a medida que for entendo melhor a situação.

Estou assistindo uma Live da Nikon Canada e perguntei sobre o novo formato RAW High Efficiency:

Pergunta:
Is High Efficiency using TICO RAW from intoPIX?

Resposta:
Hi André, Yes, Nikon collaborated with intoPIX for the new High Efficiency RAW file type.

Press release:

intoPIX TicoRAW Technology Added with High-Efficiency RAW Recording of Nikon Z 9 Flagship Mirrorless Camera
A smart strategic move that will allow camera professionals to benefit from higher resolution with still & movie RAW format, while significantly reducing storage

Mont-Saint-Guibert, Belgium, December 7, 2021 – intoPIX is pleased to announce today the successful integration of the TicoRAW technology into the new generation of Nikon cameras, including the latest flagship Z 9 mirrorless camera.
Nikon made the bold strategic move to select the intoPIX TicoRAW technology: leapfrogging existing camera limitations to meet all advanced and upcoming requirements of imaging professionals, whether in live sports, film, wildlife documentaries or other challenging environments. Thanks to this addition, the new Z 9 camera offers High-Efficiency RAW recording up to 8K and 60fps (available through the 2022 firmware update), preserving all the benefits of the RAW format, while ensuring very low power processing and very fast transfer speed.

With TicoRAW, the full quality of the captured sensor data is preserved while reducing the bandwidth and the storage needs. It can be used for both Still pictures and RAW movies. This patented technology offers high image quality, and the capability to manage very high resolutions, high frame rates and high dynamic range workflows. TicoRAW is the world’s first RAW codec that can offer compression efficiency with such low complexity. It also has the advantage of retaining this very fast format for editing, regardless of resolution and/or frame rates used.

“intoPIX is really proud to work with Nikon. Together we share the same ideals and passion: offer ever more beautiful images and videos, at anytime, anywhere in the world. Experience image-making like never before.” explained Gael Rouvroy, CEO at intoPIX.
With this latest revolution, intoPIX and Nikon invite all camera enthusiasts to enter this fantastic world of limitless imaging.

The two companies welcome everybody to contact their respective teams to sample the intoPIX TicoRAW technology solutions and the new Nikon cameras.

Segundo a matéria essas são as taxas de compreensão.
Só faltou o de/para com os nomes que a Nikon escolheu.

Uma baita câmera com mudanças drásticas.
Eu não compraria nem com o dólar à 3, câmeras com esse valor tende à desvalorizar muito mais que às intermediárias.
Só queria saber se as versões III das Z6 Z7 vão ter esse novo processador, achei até estranho ser 10x mais rápido

Dólar a R$2 daria para se aventurar
