Compressed RAW (cDNG) Workflow

MAVO LF/MAVO/TERRA 4K can record compressed RAW as cDNG with adjustable compression ratio without external recorder. Current firmware KineOS6.1 supports three different compression ratios, 3:1 and 5:1 and both of them get super good image quality and enough room for grading work.

Generally, there are three types of CinemaDNG format so far:

  • Uncompressed CinemaDNG: KineRAW-S35, KineRAW-MINI and KineMINI/KineMAX can record in-camera CinemaDNG natively. The uncompressed CinemaDNG is supported by most post software.
  • CinemaDNG with Lossless Compression: it is also friendly for post softwares. However, for high resolution and frame rate, no matter uncompressed DNG or lossless compressed DNG, data rate is too large to record more than 4K 60fps image in camera.
  • CinemaDNG with Lossy Compression: or cDNG. With different compression ratio, it is suitable for recording high resolution with high frame rate like 6k 50fps. However only DaVinci Resolve and SCRATCH v9.0 support cDNG natively now.

Insanely Fast SCRATCH V9.0

SCRATCH V9.0 natively supports compressed RAW as cDNG in the best way for Kinefinity footages: as soon as importing clips into SCRATCH, it will apply the LUT when monitoring, and will link the audio file automatically. If disabling the LUT, RAW with native KineLOG3 obtained is the same with ProRes with KineLOG3.

If you are familiar with the workflow of SCRATCH and enjoy the efficiency it brings, we recommend SCRATCH v9.0 as color correction tool of cDNG or SCRATCH Player Pro for DIT.

Davinci Resolve 14/15

Davinci Resolve 14/15 natively supports cDNG, so you can edit and grade over cDNG directly in Resolve. However, for RAW, different DI software may have different decoding ways and get different images. Since the Resolve does not optimize the Kinefinity footages, there is a huge difference on exposure and color over KineLOG3 ProRes footages if importing cDNG footage directly. Good news is that you can get RAW images with native KineLOG3 by setting RAW decoder properly in DaVinci Resolve. It greatly simplifies post workflow on cDNG RAW in Resolve:

  1. Project Setting | Camera RAW:Launch DaVinci Resolve: [Project Setting-->Camera RAW];
  2. Set Decode Using: choose [Project] and confirm the RAW profile is [CinemaDNG];
  3. Set RAW Decode Parameters:
    • White Balance: choose [Cloudy];
    • Gamma: choose [Linear];
    • Lift: choose [3.2];
    • Tint: unboxed, default setting is [10].

After above setting, Kinefinity cDNG could be imported in batch to get RAW with native KineLOG3, correct exposure and correct color. Similar to ARRI RAW process, footages are imported to Resolve to get logged clips, very convenient and intuitively. No matter grade clips directly from LOG color space or load 3rd-party LUT, the workflow will be smooth and highly productive .

Above settings as following:

Note: Recommend to employ the official LUTs as the starting point for the grading work.

  • KineNEUT, fit for TERRA 4K;
  • KineNEUTM, fit for MAVO LF/MAVO.

If the LUT is selected when shooting, the clips folder will contain the LUT, which is convenient to load it directly in post work. The above LUT is also available in Kinefinity Official LUT Collection.

 

压缩的RAW(cDNG)流程

MAVO LF/MAVO/TERRA 4K摄影机可以机内直接录制压缩的RAW素材cDNG,而且压缩比可调,当前固件KineOS6.1支持3:1和5:1,这两种不同的压缩比,无论是哪一种均能够获得超高的画质和超大的后期调整空间。

目前CinemaDNG分为三种:

  • 无压缩的CinemaDNG:在KineRAW-S35, KineRAW-MINI, KineMINI/KineMAX上,原生机内录制CinemaDNG素材,这个格式大部分后期软件都支持;
  • 无损压缩的CinemaDNG:这个格式也是后期比较友好的格式;但是无论是无压缩还是无损压缩,对于高分辨率高帧率的素材而言,码流都过大,在机内录制时很难录制超过4K 60fps的画面;
  • 有损压缩的CinemaDNG:简称cDNG,可以具有不同的压缩比,对于机内录制高分辨率高帧率(比如6K 50fps)素材非常适合。但是支持的后期软件有限。目前仅达芬奇Resolve和SCRATCH v9.0支持。

高效的SCRATCH V9.0

SCRATCH V9.0原生支持压缩的RAW素材cDNG,对Kinefinity的素材具有最好的支持:导入素材进入SCRATCH即可套用监看时的LUT,和自动链接音轨文件。禁用该LUT之后,则获得带原生KineLOG3的RAW素材,和带KineLOG3的ProRes一致,可以加载中性Kine NeutralM LUT或者其他标准LUT。

如果你熟悉SCRATCH的操作流程,喜欢SCRATCH带来的高效操作,则推荐使用SCRATCH v9.0 作为cDNG的调色工具或者或者SCRATCH Player Pro作为DIT工具。

全面的达芬奇Resolve 14/15

达芬奇Resolve 14/15原生支持cDNG,从而在达芬奇Resolve里面,可以直接对cDNG素材进行剪辑和调色!此外对于RAW素材而言,不同DI软件解读方式可能不一样,会获得不同的画面。由于达芬奇Resolve未对Kinefinity素材进行优化,所以直接导入cDNG素材,和KineLOG3素材在曝光和色彩上均具有较大的区别。但是通过在达芬奇Resolve的RAW解码设置,可以获得带原生KineLOG3的RAW素材,非常方便加载标准LUT或者调色:

  1. 项目设置 RAW:打开达芬奇Resolve,在Resolve里面打开【项目设置】,找到【Camera RAW】选单;
  2. 设置 RAW解码方式:选中 【项目】,并确认RAW配置文件为【CinemaDNG】;
  3. 设置 RAW解码参数:设置如下参数:
    • 白平衡:选择【多云】;
    • Gamma:选择【线性】;
    • 暗部:选择【3.2】;
    • 色调取消选中,默认【10】。

设置完毕之后,即可批量导入Kinefinity的cDNG素材,即可获得带原生KineLOG3的RAW素材!这样和ARRI RAW类似,导入达芬奇,即可获得LOG素材。非常方便、直观,不管是直接从LOG进行调色还是加载通用LUT,都可以大幅加快工作流程。

提示:推荐使用加载官方LUT作为调色起点:

  • KineNEUT,适合于TERRA 4K;
  • KineNEUTM,适合于MAVO LF/MAVO。

如果拍摄时候选择该LUT,则素材文件夹就包含该LUT。方便直接在后期调用。也可以在Kine摄影机LUT汇总里去下载上述LUT。
