What you are seeing is moire artifacts. The 240fps is pretty much a gimmick and will look like that in most scenes. It's a two fold issue, first is that even though the output is in 1080 it's actually capturing in 720p which is why it looks soft. The other issue is that even taking in the info at 720, 240fps is taking in a ton of "information" and the processor isn't capable of a high enough bit rate to actually process the information so you get artifacting like in your example. The 120fps looks good though so I'd have l just stick with that. If you shoot above 180 degree shutter you can also get away with further slowing the 120fps in post with good results.
The screenshots above is the result of 120fps. I didn't use the 240fps at all. That's why i'm confuse about this. The 240fps is worst than these results .
What I mean by 240ss is the shutter speed setting.
The artifacts you’re seeing might be from line skipping, which the camera may need to do in order to process the data fast enough to achieve those high frame rates.
