Recently I produced a video putting Wressle Castle in its landscape context. The idea is to briefly illustrate the results of a landscape survey. I’ve put this post together to explain how I created the video with free software.
To start with, here’s the video itself:
It was inspired by a paper in Internet Archaeology “Google Under-the-Earth: Seeing Beneath Stonehenge using Google Earth – a Tool for Public Engagement and the Dissemination of Archaeological Data”. If you don’t want to click that link, it discusses how Google Earth can be used to create a landscape tour, showing features, locations of trench, and including a voice-over. The purpose is to use Google Earth as an outreach tool.
I started out by establishing what it was I wanted the video to show and to write a script for the voice-over. The video starts out by putting Wressle into the context of northern England, highlighting some notable properties owned by the family who built the castle. It then zooms in to the parish of Wressle, showing key features such as the nearby river and the village. Finally it zooms in again to focus on the area immediately surrounding the castle.
Once I worked out what I wanted to show, the next step was marking it out on Google Earth. It’s now free to use, and you can plot points and areas, labelling key features or showing the outlines of certain features as you choose. I then recorded the audio track, first on my phone and later using a USB microphone hooked up to my computer with Audacity for better audio quality. Audacity also allows you to edit the sound file. The audio track gave me a framework for the video around which I could base the timings for moving the camera. What I did notice was that as soon as I sat in front of a microphone and tried to read from a piece of paper it was very easy to trip over what I was saying. Rather than trying to do it all in one take, I recorded one or two sentences at a time. It was a bit painstaking, but worked in the end.
Google Earth has a tour function which will move the camera round in a manner you decide. However, as I wanted to sync the video to the audio, I felt I could do it by hand. I created pins on the map for key landmarks mentioned in the audio, and they appeared in the menu on the left. By double clicking on them in the menu, the camera smoothly zoomed in towards them. Check boxes allow you to toggle what appears, so if you want an invisible point which you can zoom to, you can still use the pins. I used the polygon option to create outlines of features such as ponds or gardens. By right clicking and choosing options you could alter the colour or fill of the shape.
To record what I had on my screen I installed Microsoft Expression, a free piece of software which allows you to capture all or part of what you see on your screen as a video. Google Earth has a toolbar on the left-hand side which lists the points you’ve marked. If you double click on one of those, the camera zooms to that point. You can also use the mouse to pan around. With the audio track playing so I got the timings right, I double clicked on the points I wanted the viewer to see and recorded the video.
Microsoft Movie Maker is another piece of free software, but is often installed on Windows computers by default unlike Expression. It allows you to shuffle video and audio about, trim it if you want, make sure they’re synced up, and add in still images in this case to complement the audio.
Altogether, a three-minute video probably took about 10 hours with drafting, re-drafting, recording audio, syncing it to the visuals, getting feedback and adjusting accordingly.
If by this point you’re still reading, I’d love to hear your feedback on the video so feel free to leave a comment below.
