Basically I could do with a crash-course in simple video editing/composition. It doesn't need to be perfect, nor does it need to look completely professional.
Essentially I am taking a Sign Language course, and part of it requires me to submit a video of myself signing. The teacher has suggested that signing a song would be a particularly good thing to include for good marks :-P
While I am perfectly capable of editing a video as far as trimming, cutting pasting etc. just altering the stream (even so far as to correct a video that had [somehow] ended up with the video in the wrong order, but the audio just fine); I have no experience whatever in changing the content, adding subtitling, including another video within the overall video.
What I'd like to do is to have a video of a choir singing a Christmas song, add in synchronised subtitles, and then myself in the corner signing along. If this isn't too much to ask?
