Thank you for the test, very informative.

Did any of you noticed that the 1Dx Mark II's motion "candence" seem like it's much more fluid than the others? It's like 30p.

That's because it is 30p; a 1dxII conforms to 30p in camera when shooting 1080p120 (4x slowmo).  No you cannot change it to 24p either.

Because I don't always trust my eyes, I hope you can all help me out here confirming either way:

- The a6500 looks to be the softest (unsurprisingly), right???

- The RX10 III looks to have the most noise, right????

-The GH5 and the Leica seem to be the sharpest???

- the a7S II colors are very... ummm... "Sony Green"???

Is this what other people are seeing too???

Sony FS5/FS700 in burst mode 12bit RAW->ProRes 422 HQ 10bit 4K DCI 120 fps no crop gives best quality, but you need an external recorder. Burst mode limits mostly not an issue if interested in slow motion, since that translates to 16 seconds or so of slow mo (enough to get to the boring threshold). This is a constraint. But this is about quality. 

This test video  has both 4K 60P and 120P shots (slowed down), to compare quality:

I think the first shot with the A6500 was a bit out of focus- because the second shot at higher ISO seemed much sharper to me.

Slow Motion 4K 120P Experiment Falls Flat

Wanted to shoot preparing a bubbly soda in 4K 120p slowed down and up close. Unfortunately, the soda was flat, and so is this video.

End trigger worked well, though - nailing the exact action. And skin tone and detail are excellent.

NX1 has been tested, above a couple of cameras, certainly above a6500 which is dead last.

And I quote

"Canon 1D X Mark II
7/10 – Quite soft with aliasing issues – could be better but nice dynamic range

Samsung NX1
7/10 – High detail but high aliasing. I do like it though.

Sony A7S II
6/10 – Soft with a crop, not exactly a stella performance

Sony A6500
5/10 – The softest yet also the one with the most aliasing, so clearly the worst of the bunch"

The question of @SMGJohn was about moded NX1, that as we know can increase bitrate to at least 160Mbps stable, on H265 (since 2014, as Andrew mentions in the same article). Normal PRO bitrate is 80Mbps.

You can get to 24p from 30p by retiming to 80% (24/30 = .8) in Premiere etc. for 120/24 = 5x slomo.

We recently shot 1DX II 120fps (PDAF worked well). Without pixel peeping didn't see any resolution reduction vs. 60p (full frame, no crop for both cases). Provides enough resolution/detail for close up and medium shots. For wides best to use 4K60p if detail is important for the shot.

Slowmotion on NX1 with bitrate hack 140mb.

Not bad, a bit of aliasing

This is a pretty picture, but as a "test" this is the worst kind of example - most of the frame is OOC (bokeh is pretty nice) and there is hardly any detail to anything. Let's see people moving around in a complex setting. If pouring water (soda) into glasses is the main use of slo-mo, then this is right on...

I have a question about the mention of the Sony data rates.  You point out the normal 120p HD recordings are at 100mbps, whereas S&Q 120p is at 60mbps, and you say therefore the normal recordings are better because they are at the higher bitrate.  However, because the S&Q conforms the recording to 24fps in-camera, doesn't that mean that the 60mbps is on the conformed 24fps (which works out at 2.5mb per frame, as opposed to 1.2mb per frame for the normal recording) , or is the compression performed before the conforming?  I'd be grateful if you could confirm.  Thanks!
