I want to create a fairy for a movie in Sony Vegas by adjusting size, dont know how?
OK so i’m creating a trailer for a homemade movie about fairies. I’m gonna be acting as the fairy (haha) so how can i make myself look really small? There has to be an effect in Sony Vegas pro (what i use) to select an area in the video clip and make it smaller or bigger without changing the background. So in effect the trees could look like giants and i an a dot. Lol. Please if you know, tell me how? Thank you SO much.

You need to mask out the background you’re in front of. There is no magic way to get Vegas (or any other editing software) to automatically track your outline and isolate it from the background.
What you do is to film the background separately. Then you film yourself against a single colour background (aka a green screen) and use the Chrome Keyer tool to “key” out the single colour background and then allow the tree background to show through.
This isn’t hard to do. It just requires a bit of preparation and some manual work on your part. To do it on the cheap:
Get hold of a bunch of sheets of the same colour (and make sure you don’t wear that colour or something close to it in your fairy outfit) and use them to cover the wall and floor of a room.
Or paint the area of the room you’re going to use. This is less likely to be possible.
If you do go along with this approach, it’s important to get the lighting right. Make sure that the lights are facing towards the wall without creating a spotlight effect. You want the wall to be as evenly lit as possible so it will “key out” easily. Also, if you use the sheets approach, make sure that the sheets are pinned tightly with as little sagging of creasing as possible. Where the sheets reach the ground, don’t pin them tight to the bottom of the wall, but allow them to curve onto the floor so you don’t get a hard line where the wall meets the floor.
Look up the help file in Vegas under “Chroma Keyer” to get full details of how to apply the effect once you’ve done this. It’s as simple as placing the tree background on one video layer, the fairy footage on another video layer above it, opening the Chroma Keyer and using the eyedropper tool to select the green (or whatever) colour in the background of the fairy footage.
You may be a little disappointed that this is more work than you might have thought, but it’s the only way to do it. But there are great advantages to doing it this way that you may not have thought of. You can fly simply by adding a box covered in the same coloured material and lying on top of it. And there’s a hundred other fun tricks like that for you to discover when you do it this way.
Here are a couple of video tutorials to walk you through the process:
