122#PIVOT VECTOR SPACE APPROACH IN AUDIO-VIDEO MIXING

ABSTRACT

Audio-Video mixing is an important aspect of cinematography.Most videos such as movies and sitcoms have several segments devoid of any speech.Adding carefully chosen music to such segments conveys emotions such as joy,tension or melancholy. In a typically professional video production,skilled audio-mixing artists aesthetically add appropriate audio to the given video shot. This process is tedious, time-consuming and expensive.

The PIVOT VECTOR SPACE APPROACH in audio mixing is a novel technique that automatically picks the best audio clip (from the available database) to mix with the given video shot.This technique uses a pivot vector space mixing framework to incorporate the artistic heuristics for mixing audio with video. This technique eliminates the need for professional audio mixing artists and hence it is not expensive.It also saves time and is very convenient.
