A Flash-cut involves rapidly flashing a series of images in quick succession, creating a disorienting or hypnotic effect. The flash-cut is a much faster version of the Match cut. 

In a truck shot, the camera moves laterally with the subject, creating a sense of movement and energy. This technique is often used to capture outdoor scenes, such as car chases, where a handheld camera might not be stable enough to capture the action.

A Locked-On video effect is when it looks like the camera is locked onto one aspect of the clip, keeping that one point in the middle even as the subject moves.

An easy way to distinguish a Locked-On from a Fixed Camera effect, is that in the prior, you can usually see the framing ‘bounce’ to keep the image in center frame.
