At our hackerspace, we have a full HD video camera (Toshiba Camileo X200) with a crappy microphone input. Therefore, we use a Thomann SC450 USB microphone to capture audio on a computer. Buying new equipment is not an option due to small budget.
After recording, the only post-production we have to do manually is synchronizing our good audio file to the video. We would like to automate that step away.
I thought about the problem a little and came up with the idea of a "magic video clip" which contains an easily recognizable sound and video sequence.
Do you know of any tools (free and open source software is a requirement!) which can help us with that? I would also be grateful for hints to tools or libraries which can be easily scripted so that we can implement synchronizing ourselves. I briefly looked at libavcodec/libavformat, but it’d take me at least a few weeks to implement it using libavcodec.
