Voodoo Doll

A second trial with the DIY camera dolly, with miniDV footage tracked in Voodoo and then post processed in Blender 2.5 including CGI elements and colouring. I've included some timelapse footage of the creation process in the video. Voodoo performs well with slow, forward motion, but there was some loss of tracking during a faster, lateral movement, so I had to base the second animation around a shorter clip than I'd hoped for.

Physically there are still some wobbles on the camera dolly but greatly reduced by using paint rollers at the track joints. A further addition to the dolly is an eye at the front so it can be pulled along from the side with a pole and hook.

The base for the skateboard dolly is two sheets of 12mm plywood bolted together. You need something to hold the tripod in place - I've used furniture coasters.
I reversed the direction of the wheel bolts for better spin. The wheel trucks have to be positioned accurately so they keep the rails parallel. For this step you will need : one Doctor Who Series Three box set and one Woody Allen box set.Welcome to the future of high-tech filmmaking.
First test run footage:

OK. Runs smoothly except for wobbles where the pipes join - at the moment I only have very loose joining plugs for them (next on the to do list.) The wheels are completely silent, track is self straightening and there's no lateral roll.

Hello Dolly! [Skateboard Dolly Part I]

It's time to upgrade the Sci-Fi Gene standard package: starting with the camera department. There are three options, any of which should improve some aspects of film quality.

1. Invest in the latest semi-professional HD camcorder for higher resolution, better image quality and all the latest built-in features.

2. Build or buy a camera rig, matte box and French shutters and 35mm adapter device to enhance the capabilities of the current camera with professional lenses and filters.

3. Sign up for a camera operator training course to learn how to get the best from existing equipment.

As you can see here I chose option 4.

The next project is a track and dolly system. I've based mine on a design featured in The Guerilla Filmmaker's Blueprint by Chris Jones, reviewed here, but there are variants of this design all over the internet. The base will be made from two 96cmx60cmx12mm sheets of plywood.

Building the wheel trucks: 8mm holes on each side of the bracket for the wheel bolts, 4mm holes on the corner for woodscrews. 8mm bolts for the wheels were cut to required length.

On each side of the bracket: bolt, nut, 2 x washer, 54mm skateboard wheel with two bearings, 2 x washer, nut.

Wheel trucks are screwed to wood blocks which can in turn be screwed to the base and easily repositioned if needed.
