It is a good versatile device. But, I cannot use tripods, monopods, or stability sticks in most places where I shoot video. In some, I cannot even use a camcorder. This device also adds weight I...

Thanks. Yes, handheld using Active Mode and viewfinder. Using the viewfinder adds an extra element of stability. It seems to be necessary for that reason alone.

This one is ok - he didn't grade it or even focus on close subjects to blur most of the frame! Mounted on his car, and straight from the camera - one of his best. :)

You really think that I do not know the difference between frame rates and bit rates?! And you think that Leica is offering 1080 at a bitrate of 120 bits per second?! and 100 bits a second for PAL? !...

You can do better if you just want 1080 120 fps, maybe

With no LCD, no ability to frame shots so this camera is not ideal just for HD slo-mo videography.

If you want 120 fps for slo-mo, the spec sheet for the Leica version of the Panasonic LX100...

Hero 4 Black coming in October with 4K30p

Plus, full manual controls of video. No LCD for viewing. So, really still mainly for attaching to your skateboard or drone. This will be clearly superior to the Sony AS100V, which has no LCD or 4K.

AX100 video

This 4K video underwent no conversion. It was just merged and trimmed in TMPGEnc without re-encoding (so it is XAVC S 60Mbps):

I understand your concern, but the unit comes from Honk Kong and is made in China; both are PAL countries. If your monitor sees 25Hz as a setting, the unit will output 25Hz if you want. I can't test...

by original it is meant the original video uploaded to vimeo, not re-encoded by vimeo.

the lx100 produces the same clips as the gh4. Get one of those 'originals' to test your software.

It has the same specs as the original, judging by the GH4 specs, (mediainfo), and he did no corrections, alterations, improvements at the very least.

Shutter speeds

Do not shoot auto - the shutter speeds will be too high in bright light. Learn best practice.


Normally, you want to shoot at double the frame rate. For 4K on the AX100, that means 1/60th...
