AT A GLANCE
- Adds V-Log L Gamma to GH4, GH5, FZ2500
- Wide Dynamic Range of up to 12 Stops
- Improved Color Matching with Varicam
- Similar Characteristics to Cineon
- Same LUT and Curve as Standard V-Log
DESCRIPTION
Upgrade Software Key DMW-SFU1 enables log video recording (V-Log L) on DMC-GH4 , DMC-GH5 and FZ2500 to offer exceptional flexibility as well as wider dynamic range for colour grading in post-production.
V-Log / V-Log L have been developed to feature similar characteristic curve to Cineon, which is a characteristic curve of film digitization. Taking full advantage of a Four Thirds sensor, V-Log L features a log characteristic with 12 stops. Both V-Log and V-Log L have the same characteristic curve and LUT (Look Up Table) can be utilised in common.
The firmware of DMC-GH4 needs to be updated to Ver.2.4 to achieve this function. Please refer to the bundled instruction manual for the activation procedure.
Activation Code from Panasonic.
This code, which is delivered on a physical card, allows you to easily install the V-Log L gamma onto the camera, giving you a flat profile that provides a wide dynamic range of up to 12 stops, improving upon the range previously attainable with the GH4, GH5, or FZ2500. The addition of this gamma also allows users to better match colour with existing Varicam systems that feature standard V-Log, as both profiles utilize the same characteristic curve and LUT. Additionally, the profile has been developed to have similar characteristics of Cineon, which is used for film digitization.
Updating your camera is a stepped process similar to updating your firmware; although, you will need this activation code along with your camera's serial code to generate an upgrade key from Panasonic's Update Portal. This upgrade code is also region specific and is designed to work with cameras distributed in Canada and the USA.
