going on a trip and want to take some video mounting my gh4 with a 12-35mm on my car hood for some fun, but there will be changing light as its a windy road, and i wont be able to adjust anything while driving. What settings would you use?

set it all up manual locked down and deal with the blown out and dark bits with changing light in post (i would like 1 long shot though), set up in full manual so the light meter is good then switch to shutter mode with a highish iso so the dof does not get too shallow and let the camera deal with the light changes, go with aperture mode and let the camera do its thing... or any other ideas? will go by trial and error but just wondered if anyone else has played with this.

any info would be great thanks!!
 
I'd use CineD for widest range possible... then experiment for the exact conditions. Contrast and light and dark spots aren't always a bad thing.

Side note: if you have a separate person available to either drive or operate, use the Panasonic Image app with the camera's WiFi to monitor and change settings. Don't do this as a solo operator/driver, of course.
 
yeah ill most likely be driving so im not going to try and juggle a tablet at the same time, i was asking because its around sunrise and certain parts of the road are facing into the sun, thanks for the tips!!
 
If you set your lens to the 12mm end, you will not need to worry about shallow DOF, as long as you set your focus somewhere near infinity, then everything should be in focus even at a fast aperture like 2.8. If you are going for realistic, movie-like motion blur, you should keep your shutter speed at 1/40th or 1/50th (or set it to 180 degrees). This shutter speed outdoors probably means you need an ND filter on your lens, even if you shoot at 200 ISO. What I would do is set the GH4 to 'S' for shutter priority, put the camera on 1/50th shutter speed, and then let the aperture auto-adjust for the exposure differences of going from sun to shade on your drive. The ND filter will also protect your lens from any pebbles, etc. that might hit your lens.
 
thanks dvdbrother, ill give that a shot, sounds like the best option as ill only get a couple of try's, ill let you know how it goes, thanks!!
 
hey there, so it ended up looking pretty good, the shutter priority helped a bunch with all the changes in direction of the sun! i was wondering though have you ever tried to smooth the exposure changes in post so it doesn't look so much like a click every time the aperture stops down or up? using FCPX and tried splitting it right on the change and running a dissolve but no love, any ideas? no stress though im happy with how its turned out... example at about 4 seconds in http://youtu.be/zkS0Qldwtqs

Thanks!!!
