Panasonic's logarithmic gamma curve designed for wide dynamic range recording.
Technical Details
V-Log operates with a black level of 7.3% (equivalent to 18.7 code values at 10-bit) and a white level of 61.3% (equivalent to 624 code values). The mid-gray range (18% gray) is at 42.7% in the V-Log signal. The format supports Rec. 709 and Rec. 2020 color spaces and can be recorded in various resolutions from UHD to 6K. V-Log L is a stripped-down variant for consumer cameras with a reduced dynamic range of approximately 10 stops, available in cameras like the Panasonic GH5 and S1H.
History & Development
Panasonic developed V-Log in 2014 in response to Sony's S-Log and Canon's C-Log to remain competitive in professional film production. The first implementation was in the Varicam 35, followed by the Varicam LT in 2016. From 2017 onwards, V-Log L was integrated into consumer cameras, initially as a paid upgrade for 99 Euros, later as standard in premium models. In 2019, Panasonic expanded the system with V-Log for the S1H, the first full-frame mirrorless camera with the full V-Log scope.
Practical Use in Film
V-Log is particularly suitable for HDR productions and projects with extreme lighting conditions. The Netflix series "The Crown" (Season 4) used Panasonic Varicam cameras with V-Log for outdoor shots with strong contrast differences. The typical workflow requires LUTs (Look-Up Tables) for conversion to Rec. 709 or other color spaces during post-production. V-Log footage initially appears flat and low-contrast, but allows for precise color grading with minimal loss in shadows and highlights.
Comparison & Alternatives
V-Log competes directly with Sony's S-Log3 (14+ stops) and Canon's C-Log3 (16+ stops), but offers a more linear curve than S-Log2. Compared to Blackmagic's Film-Log, V-Log shows better noise characteristics at high ISO values. For productions with mixed camera manufacturers, V-Log complicates color matching, as each manufacturer uses its own conversion LUTs. RED's REDLogFilm and ARRI's LogC remain dominant in high-end production, but V-Log is establishing itself as a cost-effective alternative in the semi-professional sector.
