How to line up 4 separate video camera audio-tracks to a pair of sync claps ?
I have 4 camera video streams, all covering the same concert. A simple hand-clap was used at both the beginning and end of the concert (approx 1 hour 20 mins) to assist in lining them up later. I will strip the audio soundtracks out from each camera and line up the 4 audio files vertically in a Reaper project….aligning the beginning handclap precisely.
Due to there being no sync device or connection cable linking the cameras during filming, I’m expecting there will be drift between the audio streams, and the ‘end of concert clap’ probably won’t line all 4 up exactly. I don’t want to break the concert up into its component songs…I want to retain them as 4 long audio streams, for editing purposes.
Please note that I’m only working with wav audio files, which have been extracted from the 4 camera’s SD cards, not from their associated 4K video files (too big to work with and not necessary !)
How do I achieve the alignment of all 4 streams with the end-of-concert sync handclap ?
Thanks very much for your help !
