R5 does amazing super slow motion equivalent to 240 fps

One thing I really like about the R5's video capabilities is that the image quality of its 4K120p ALL-I format, which outputs at a staggering 1880 Mbps, is so good that you can slow down the footage another 50% in post giving you effectively 240 frames per second—and it still looks good.

Have a look at the last clip in this little sequence and see what you think.

By the way, this is the area where I grew up and still live today and it just happens to be the best Snowy Owl country in Eastern Ontario. How great is that?

I am confused by what you did and what you are claiming.

How slow the 120 fps footage is in the rendered video depends on the frame rate you choose for the timeline. If you choose 60 fps, then stretch, the slowdown is 2X. If you choose 24 fps, and stretch, the slowdown is 5X. So by changing the timeline fps I can more than double the slow down with no loss of resolution.

So, what do you mean you can slow down another 50% in post exactly? And why is that equivalent to 240 fps?

Just to show I shoot 120P 4K with the R5:

I think I used a 30p timeline, so the slowdown is 4X. But I could have increased the slowdown by 25% with a 24p timeline to 5X. Now if I wanted more, then I would have to interpolate frames. Is that what you did?

240p with with a 60 fps timeline is 4X, with a 30p timeline it is an 8X slowdown. Is that what you are showing from the 120 fps shot video? 8X?
