Explanation of Clark Scene Files:
Both the Panasonic HPX-2700 and HPX-3700 cameras come with various Clark Media stock scene files with varied
matrix and color correction adjustments. The following is an explanation of each one of these scene files and how
they could be applied in the field for desired looks.
THE FOLLOWING SETTINGS APPLY TO ALL SCENE FILES (NOT FACTORY):
-Reading a scene file will not affect your system mode. You must select your system settings independently.
-Scene files have matching values applied for all three L/M/H gain settings.
-Detail is set to on. (The default is a minimal amount of H/V detail)
-Gamma Mode Select is set to the HD gamma curve.
-Manual Knee is on.
Here is a description of all the gamma curves available in the Gamma Mode Select menu:
HD-This will produce an image with the highest contrast at the highest video output. This will give you the least
amount of latitude available in the gamma curves. Do not use this curve if there will be color correction in post.
(This curve is loaded as default for all of the clark stock scene flies).
SD-This will produce an image with a high contrast at a higher video output level than any other film like or rec
curve. This will give you a less amount of latitude therefore is not a good choice if there will be color correction
added in post.
FILMLIKE 1-There are 3 degrees of Filmlike curves. Filmlike1 has the most contrast. This will produce a no-
ticeably lower contrast image than HD/SD with softer gradations especially in the mid-tones.
FILMLIKE 2- This curve will give a considerably less amount of contrast than Filmlike1. However it still pro-
duces soft gradations in the mid-tones.
FILMLIKE 3- There is a significant difference between Filmlike2 and Filmlike3 (Refer to diagram below). This is
also a much flatter curve where as your video level rises there is a softer grade of contrast change.
VIDEOREC- This curve will give you more latitude than the Film-like curves with a considerably lower contrast.
*All of the above gamma curves use knee point and knee slope. The knee function of the camera compresses high-
lights above your set knee point. The knee slope adjusts the actual amount of compression applied to your curve.
The higher the knee point is set, the more compression you will get in you highlight areas.*
FILMREC- Film-Rec gamma curve gives you the widest dynamic range therefore providing the most amount of
information in post. Your image will be very dark and flat looking with less saturation. You will want to apply this
curve if your product will be going to post for color correction. (Best if used with a look up table set in your moni-
tor.)
*Film-Rec gamma curves apply a dynamic level setting from 100% (equivalent to an video curve with no knee) to
600% (most dynamic level the camera is capable of) which adjusts how flat you want your linear curve to be. Black
stretch is also applied to adjust the amount of detail in your shadows. Your knee functions do not exist in
Film-Rec.*
**Don't use Film-Rec when in DVCPRO HD (The 8 bit codec will not take advantage of the dynamic level)**
