Panasonic x Arri: Software program improve provides Arri LogC3 to Panasonic GH7 (and GH6): Digital Images Assessment
Final week’s launch of the Panasonic GH7 was thrilling for video shooters, with options like 32-bit Float audio and inner ProRes RAW recording making headlines. Nevertheless, Panasonic additionally made a parallel announcement that can flip some heads.

Different ISO settings do not change the acquire utilized and easily shift the center gray level, exchanging DR between highlights and shadows. Arri LUTs are usually calibrated to ISO 800.
The GH6 and GH7 do apply differing acquire between their ISO settings, which means the identical quantity of spotlight vary is maintained. Panasonic says it has rigorously calibrated every ISO setting in order that the colour and tone response is correctly matched again to the LogC3 ISO 800 curve. This implies the digital camera can be utilized at completely different ISO settings or in Auto ISO however nonetheless ship footage that works effectively with Arri LUTs.
The bottom ISO of the GH7 in LogC3 mode is 320 and also you need not restrict both the GH6 or GH7 to the vary through which they will use their twin sensor readouts (DRBoost mode), you merely seize a cease much less spotlight when working outdoors this vary.
Which means Panasonic customers will have the ability to use the Arri Look Library, a library of LUTs that can be utilized to transform LogC3 footage to considered one of dozens of Arri’s high-quality appears to be like.
Moreover, because the GH7 can retailer customized LUTs, these Look LUT recordsdata might be loaded into the digital camera. When mixed with Panasonic’s real-time LUT system, customers even have the choice to output a particular Arri look straight out of digital camera, or to proxy recordsdata.
LogC3 is an elective $200 improve that customers can set up on their cameras by buying Panasonic’s DMW-SFU3A software program improve key. Panasonic notes that the improve will even work on the Lumix GH6, although with out the added benefit of Panasonic’s real-time LUT system.
Panasonic licenses ARRI LogC3 from ARRI for the LUMIX GH7
Newark, N.J. (June 5, 2024) – Panasonic is proud to announce a brand new Software program Improve Key DMW-SFU3A (offered individually) on the LUMIX GH7. With this improve, ARRI LogC3* is enabled, and seamless shade matching with ARRI’s digital cinema cameras might be achieved. The picture processing of the ARRI LogC3 curve on LUMIX GH7 has been licensed by ARRI for the implementation of this operate. The choices for Log recording, which supplies wealthy shade data and vast dynamic vary, have been expanded to incorporate ARRI LogC3 along with the traditional V-Log, additional bettering LUMIX’s workflow compatibility.
*ARRI LogC3 is a Log gamma developed by ARRI and utilized in ARRI digital cinema cameras. Please notice: ALEXA 35 makes use of ARRI LogC4.*On the LUMIX GH7, ARRI LogC3 can be utilized for 10bit recording in Artistic Video mode.

It is usually doable to retailer the LUT bundle for 709 conversion (ARRI Look Library LogC3 to Rec709 3D-LUTs) within the LUT Library of the LUMIX GH7 and mix it with the REAL TIME LUT operate to seize movies with ARRI LUTs straight out of the digital camera.*As of June fifth, 2024
2. Manufacturing workflow appropriate with quite a lot of viewing gadgets
Utilizing the ARRI Look Library (log-to-log), you possibly can shade grade movies recorded with ARRI LogC3 and apply the specified ARRI Look throughout the log house.

The LUMIX GH7 can simply match colours in taking pictures conditions the place cinema cameras, such because the ARRI ALEXA Mini, are used as the principle digital camera. Moreover, when DMW-SFU3A is put in, ARRI LogC3 within the LUMIX GH7 employs a curve that conforms to the usual sensitivity of ISO 800 of the ARRI digital camera.
