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. In today’s era, significant advances are happening constantly in the field of Information Technology. The development in the IT related fields such as multimedia is extremely vast. This is evident with the release of a variety of multimedia products such as mobile handsets, portable MP3 players, digital video camcorders, handicams etc. Hence, certain activities such as production of home videos is easy due to products such as handicams, digital video camcorders etc. Such a scenario was not there a decade ago ,since no such products were available in the market. As a result production of home videos is not possible since it was reserved completely for professional video artists. So in today’s world, a large amount of home videos are being made and the number of amateur and home video enthusiasts is very large.A home video artist can never match the aesthetic capabilities of a professional audio mixing artist. However employing a professional mixing artist to develop home video is not feasible as it is expensive, tedious and time consuming.
