How audio and video are merged?
Have you ever been curious about how the audio and the video get merged in a recording? Our technical experts can abridge you with the most authentic explanation.
When a singer sings a song, his video and audio both are recorded. As these are the two different inputs of recording one is video and other is audio, it is likely that there may be some time difference between the two and if not corrected or synchronized the lip movement may not match with the song.
What is the method or software by which these two are merged with each other and well synchronized? Is it done by the electronic circuitry itself or some application in the system?
