She asked me to make opening credits style introduction. I thought of an old, possibly mid-60s horror movie. First thing I did was use Audacity's noise removal plug in to cut down on the ambient noise from her outdoor recording. It was the first time I had ever tried it and it did a great job filtering out the breeze and other "white" noises.
Once I had rendered her cleaned up audio to the video, I set that file aside and started a new project in OpenShot, a video editor similar to Window's Movie Maker, to make the title sequence.
OpenShot uses a time line to mix together several video and audio tracks at once. The top layer is reserved for the text part of the credits. Those were rendered by a Inkscape, an open source vector graphics editor. I wouldn't begin to know how to use Inkscape, but OpenShot has many pre-loaded templates included. All I had to do was choose one, add my text and let it go.
I used the other layers for the cemetery images from the video shoot. Using some of OpenShot's video plugins and animation controls I added an inversion effect and then an animation control to give the images a vibration. I used The Gimp, a great graphics program, to add some lightning effects to a couple of images and finally, Audacity to mix my audio files.
