Some quick calculations on a captured frame from your vid.
Distance object moved in one frame ~ 145 pixels
Length of object ~ 30 pixels
Motion blur at 60 fps and 1/2000 exposure ~ 5 pixels
From this, if the object was 1 inch long it travelled about 5 body lengths in 1/60th sec.
giving 300 inches per second or about 20 mph
very fast for a small insect, but still possible. Increase in size estimate gives proportionate speed estimates.
1/2 inch object about 10 mph (possible for an insect)
2 inch object - about 40 mph (faster than possible for an insect)
3 inch object - about 60 mph (faster than possible for a bird)
12 inch object - about 240 mph (faster than credible for a drone)
36 inch object - over 700 mph
The straight trajectories seem unlikely for insects, but certainly not impossible.
If the object passed in back of the tree, it appears too large to have been a bug or bird.
The quality of the motion blur is extremely correct, largely ruling out CGI.
I only looked at one data set, and the original images would be far more accurate and believable.
Using common sense it is far easier to believe that these are insects, flying in front of the tree than any other explanation.
Drones would have to demonstrate unheard of performance. Man sized craft would be travelling far to fast to be earthly in origin.
So I am left with either unusual bugs ( 99% ) CGI hoax (1%) or a device of non normal origin ( impossible to estimate).
