Will the GH4 Get V-Log? All about V-Log L


STOP PRESS: Lookout in the UK for leading Panasonic spokesperson, Mark Baber (Product & Marketing Specialist of Imaging Marketing & Consumer Group), who will be demonstrating it around the country at Panasonic Show Events.

The rumour mill going around since early this year that there may soon be a firmware update that will contain a V-Log L (Lite) – a logarithmic curve similar to a scan from negative film which is also highly compatible with conventional film workflow would be greeted with hallelujahs from Panasonic GH4 filmmakers and potential customers.

GH4 owners and more specifically graders of Panasonic’s flagship GH series micro four thirds camera footage are waiting in eager anticipation. But don’t hold your breath just yet – because it may never happen! At the moment all we have seen is some video clips showing  some of Panasonic’s senior imaging engineers testing it out and we don’t really know the full results of those tests. But lets say it will arrive, what will V-Log L offer users over the conventional profiles such as Cinelike D and Cinelike V found in the GH4. In layman’s terms lets take a look at what a Log does with information drawn from Panasonic’s amazing Varicam35 documentation.

The light captured by the sensor is converted to electronic information by the sensor. Therefore, in simplistic terms light information and electronic information have a proportional relation. Log curve characteristics show the relationship between the linear domain video signal and exposure measured in stops, and a change in each stop of exposure increases or decreases the signal by almost the same amount. V-Log L will reproduce the complete tonal range captured by a CCD or CMOS imager, the V-Log image can be described as the “Digital Negative” of the image acquisition process.

V-Log Benefits:
  • Its fantastic when you have to shoot scenes that have a high level of contrast. 
    There’s perceptively more dynamic range.
  • It will perceptively work much better than Cinelike D/V in low light.
  • It provides better reproduction of detail in a scene than you would normally get without it.
  • You can grade with LUTs (Look UP Tables) a V-Log L picture much more easily than a non V-Log L picture recording. Davinci Resolve, FCP X, Adobe Premiere/After Effects users will rejoice in being able to work with a very flat picture. The Atomos Shogun also has a LUT feature that will work better with V-Log L employed recordings.


GH4 users await in anticipation for more news on V-Log L’s release.
