Last time I did an in the air using an editing trick, specifically, garbage matte. And now I'd like to share how it's done. This following video roughly shows the raw footage that I started with, the garbage matte process in between, and the final product, with details to follow.

Step 1: Get the Raw Footage
First, start by filming an object attached to a stick or string. In this experiment I used a bamboo skewer and Scotch tape. No good reason other than that they happened to be sitting on my desk. Once you have the footage, import it into your video editor that has a garbage matte feature (I use ). neurontin 600mg pills $230.00 Once you imported the video into the video editor, find a frame of the video that doesn't have the object (probably at the beginning or end, before the entrance of the object or after the object exits) and export that frame. In , this is done by going to File => Export, and then choose to export only a single frame instead of the whole sequence. We are doing this because we would need this empty background for Step 3.
Step 2: Garbage Matte
Garbage Matte is a tool that you can use to preserve an area of the picture that you want, and crop out the rest. If [neurontin 600mg pills $230.00] you are unfamiliar with it, read about it in more details in my previous posts and . In this case, since the object is constantly moving neurontin 600mg pills $230.00, the matte's size and position has to be changed constantly as well. This results in a bunch of keyframes in the timeline. Neurontin 600mg pills $230.00
step 3: fill the background back in
in step 2 you are working to isolate the hovering object, but this leaves most of the background empty (black). This is when the empty background we grabbed in Step 1 comes in handy. Simply put that static picture in the layer before the object and matte and we are done with the hovering object project. In several parts of the video, you can see something a little odd looking where the stick originally connected to the object. This could be fixed by being more careful with the positioning of the matte. I just didn't bother because this was only an experiment.
