I used a video camera to film the shots and sequences of my film trailer. Whilst filming I used a tripod to balance the camera so that the filming was steady and not shaky, using the tripod meant my recording was controlled and so went the way I intended.
I also used the video camera to record sound effects as it was better quality recording than from my mobile phone. I recorded my singing as well, I then used Audacity to combine with an instrumental backing track that I had previously removed the original vocals from.
Once I had all the footage I needed, I uploaded it onto the computer via the USB cable that came with the video camera.
