how do u make a AMV?

Answer 1

By taking clips from various series and synchronizing them with a musical track, you create a feeling of synchronisation with the audio using editing, lip-sync, and digital effects techniques

Editing - Using different clips from the video source and changing between them at specific times is the most important tool the AMV creator has. Often both the events in the video and the transitions between the clips are synchronized with events in the music.
Lip-sync - the synchronization of the lip movements of a character in the original video source to the lyrics of the audio, to make it appear as if the character were singing the song.
Digital Effects - Using video editing software (like a non-linear editing system) the video source can be modified in various ways. Some effects are designed to be unnoticeable (such as modifying a scene to stop a character's mouth from moving) whereas others are intended to increase synchronization with the audio, or possibly create a whole unique visual style for the video.
Some editors use original and manipulated animation, both two-dimensional and three-dimensional, in AMV works. Such additions are often used for visual effect or to convey a story that cannot be done using only the original video source.
