So I finally got a spare moment to look at Panasonic's new smart coding software that will be available for most of their new cameras coming out including the new 3,5, and 6 series cameras. I tried to load up a 631LT with the new firmware, which also includes the new ONVIF config tool capability, and due to a weird network hiccup I bricked the camera.
So after sending that back to Panasonic to be repaired, I decided to try a WV-SFN311, loaded the new 2 step firmware ( which is now encrypted) and breathed a sigh of relief as I didn't brick this one. Over all their isnt that much has changed on the surface.
So the Smart coding runs only when transmission priority (or mode) is set to VBR (variable bit rate ). Normally a WV-SFN311( 720p) will have an average bit rate of no more than 2048 KB when running at 30FPS. At 30FPS on my desk with no movement or picture change, with out smart coding the average bit rate is around 1200KB, which is about where is should be given the small area its covering. With Smart Coding turned on the average bit rate is around 270KB with the camera in same exact conditions.
the camera still "throttles up" when movement is taking place on the screen increasing the bit rate to what it would be if you were not running in smart coding mode, but after about 5 sec its starts slowly moving back into smart coding mode and returning back to the low bit rates again.

WV-SFN311 in normal mode with Frame rate as priority
I pulled a 60 second copy of the streams in both modes using FFMPEG into H.264 files with no movement on either of the stream copies.
311_FR is the camera in normal mode with FPS as the standard, 311_VBR_SC is the file size after running with the Smart coding on. its a little less than 25% smaller with almost no losses. I am not sure how to Embed video here yet so as soon as I figure that out I may post them in the comment section unless john beats with a full article for every one first. Going to try a 1080p model as soon as I can get one up and running with out bricking it.
It seems like a great idea if you record 24/7 if you just record on motion it may not be worth it.
