As soon as Samsung will publish the codes, one will can go with compiling and improve phone camera performance of the S5

Usually companies never publish source files that have any value. They just compile this modules or drivers, and never publish any sources of applications.

I think the S5 has a different sensor.

One obvious issue in using the Galaxy S 5 as a 4K camcorder is the lack of in-camera stabilization. But 4K gives you a lot of leeway in editing, including using software stabilization. Here is a 4K video stabilized using the plug-in in Sony Vegas Pro 13 applied to each clip:

Here is the original video that was posted above prior to stabilizing in post:

One obvious flaw is that in a scene with a wind-waving branch, the software algorithm tries to de-shake the branch and therefore causes the background to shake! Otherwise, the software appears to do a pretty good job without apparent resolution loss viewed at 1080.

Another stabilized 4K video:

Accordion playing, jugglers, a carousel, bowling, chess, a foot-model shoot, a jazz band, diners.

Select 2160 for best viewing on any screen.

Use this S5 to control gh4 of start, stop, zoom in ..and both together shooting 4 k but how or could be?

Galaxy S5 4K Video with Tripod

4K Video shot indoors in successively dimmer surroundings: From a reasonably lit library reading room, to windowless library rooms, to a dark window-lit dining hall, and finally to a windowless library illuminated by translucent marble and kept dim so that the marble shines, relatively. This last setting shows the limits of the Samsung.

Each building is preceded by outside shots so that the contrast, if any, of color and resolution can be easily made with the indoors shots by space.

All shots used a miniature tripod to prevent shake.

Sony Z2 video 4k is Ugly and soft.

@derek, I observed a comparison video and agree, the Sony did not appeal to me, other than the internal stabilisation feature at 4K. Can't really comment if the Sony stabilisation at 4K is any good, I didn't like the footage to begin with. Thanks for confirming the Sony model. New high end phone off the radar for now.

@markr041, agree. Even on a tripod, the camera clamp needs to be secure, wind appeared problematic in some instances of other shooters sample footage observed, kind of defeats the purpose of convenient device, solid tripod and clamp, IMO. Gazercam looks great. I had alredy observed the product specs of the Ikan X3. Gazercam handle/tripod base, looks better. I might hold out until the next gen Samsung and review again. Great footage, Mark. best regards,

Here you go: the Galaxy S5 on a 3-axis digital stabilizer (Ikan X3). No tripod, no monopod, just one hand. Balancing is automatic (3 seconds):

The 4K video:

More experimentation with the 3-axis gimbal. Following people, following action - and a circle-around a playing pianist in Washington Square Park, NYC.
