Experiment on Panasonic HC-V770 at 240fps and super slow motion

Experiment on Panasonic HC-V770 to take video directly on my project screen. Like the HC-WX970 and HC-VX870, it offers high speed video recording at 120fps with 1080p. The native recording is done 1080/60p. With the slow motion feature,it can record at 120fps. The Intelligent Frame Creation of the Crystal Engine on camera can interpolate to an equivalent of 240 fps. This test is to see how smooth of 240fps can be if I shoot at slow motion footage on my project screen. That gives me 8X slower than original
