For high quality audio, sound is separately recorded with an audio recorder when video is recorded. So, it is necessary to synchronize the video with the audio. This application reads multiple MTS (common camcorder recording format) and a MP3 file using FFMPEG library and and present them as wave forms for easier alignment. Using left and right arrow keys with the combination of Ctrl and Shift keys, users can zoom in and out and shift the audio relative to the video.
