This is a typical example of a high-flying fastwalker moving across the sky. Sometimes YouTube hoaxers will video a satellite, then alter the speed of the video. It does not appear to have happened here. The creator of this video provided an excellent description of this videotaping session:

Using a Pulsar Recon 550 digital monocular and a Yukon MPR, what was initially thought to be satellite was tracked and film. You will see in the footage that the first object is quite faint but you can see it moving in a straight line through the shot. Then a second object moving much quicker enters the shot but as it moves parallel to the first object and too the right of it, it suddenly moves away from it. It clearly increases its distance from the first object.

This UFO, taped in Israel on April 28 bears a resemblance to one taped in Ireland last December. this could be because the light sources are similar in intensity, but a close look at the unzoomed imagery suggests a subtle similarity in shape.

Two witnesses have separately filed reports with MUFON that suggest that they saw the same or very similar triangle UFOs 1,200 miles apart on April 27, 2013. The reports were two hours apart, the first in Tennessee and the second in Colorado. The first was described as light gray with curved angles, and the second as having ’rounded’ angles and being ‘white.’ Both the color and the rounded angles are unusual, and do suggest that this may have been the same object.

The Tennessee witness stopped his car directly under the object and got a good view of a circle of light on its undersurface. The second, in Colorado, observed it transit the entire sky from east to west in a couple of seconds, moving at that point at very high speed.
