How to export video to a folder other than the root of the project

Hey guys!

I'm making a little application that basically allows users to record small video diaries from their webcam and integrated mic. (It'll be used as a design probe). I've made everything work using the VideoExport and Minim libraries, but I can't possibly set it up so the exported videos get saved into another folder! I tried this:

videoExport = new VideoExport(this,"logs/log"+nameid+".mp4",cam);

but it yields "Could not run the sketch (Target VM failed to initialize)".

When I try it with the minim recorder:

recorder = minim.createRecorder(mic,"logs/log"+nameid+".wav");

it yields NullPointerException. Am I doing something wrong? Thanks for the help
