V-Log L

V-Log L is Panasonic's proprietary log video profile for Micro Four Thirds cameras. It is a modified version of V-Log, the log gamma used in Panasonic's professional VariCam cinema cameras, scaled for the dynamic range capabilities of M43 sensor systems. The L stands for Lite, indicating a simplified implementation compared to the cinema version. V-Log L is available as a selectable picture style on compatible Panasonic M43 bodies and records a flat, desaturated image intended for post-production colour grading.

V-Log L footage requires a LUT to convert to a viewable colour space for delivery. Panasonic provides an official V-Log L to V-709 LUT available as a free download from its website. V-709 is a broadcast-standard colour space suitable for most delivery formats. The LUT can be applied in DaVinci Resolve, Adobe Premiere Pro, Final Cut Pro, or any professional editing application that supports LUT-based colour correction. Using a custom grade instead of the supplied LUT is also common in professional workflows.

Many Panasonic M43 cameras that support V-Log L also include a monitor LUT function, which applies the conversion LUT to the camera display in real time without affecting the recorded signal. This allows the operator to see a graded, viewable image on the LCD or EVF while recording in flat V-Log L. Without a monitor LUT, the on-camera image during V-Log L recording appears flat and washed out, which can make exposure and focus assessment more difficult on set.

V-Log L is available on Panasonic's video-focused M43 bodies including the GH6, GH7, and G9 II. On some older Panasonic M43 bodies, V-Log L was a paid firmware add-on rather than a standard built-in feature. OM System's equivalent format is OM-Log 400, which uses a different gamma curve and colour science but serves the same purpose of providing flat-gamma footage for post-production grading.
