Until recently, only high-end video cameras permitted frame rates of 500fps (PAL) and above but Sony changed that when it introduced the 1-inch sensor RX10 II and RX100 IV. Both cameras are capable of shooting 2-second (quality priority) or 4-second (shoot time priority) clips at 100fps, 250fps, 500fps, and even 1000fps, though the higher speeds will result in a decrease in image quality.
We recently came across a very nice video by James Dart on YouTube. He chose to use his RX100 IV to film the coast of Plymouth using frame rates shot between 120-250fps and SLog2 to preserve the quality of the file. He then conformed the footage to 1000fps in Final Cut X.
