How do you zoom into a virtual set without moving every component? Is there a tool for zooming in? Please reply if possible.
Assuming you have the virtual set set up in 3D, then you can just move the virtual camera forward. Which you can do using the tool in the top right corner of the Viewer, with the two arrows pointing opposite directions.
Otherwise, if you are in 2D, you will need to use Scale to create the illusion of zooming in.
Where is scale?
Scale is in the Transform controls for each layer.
How do I zoom in and make it show on the final video?
You'll need to key-frame it. If you are scaling it for example, you'd go to the scale attribute and click the circle to the left of the word scale. It will change color (blue if you are in HF3, I think blue in HF2?) and it will create a point in the timeline to show that you have a keyframe there. Now, you can play it forward a little bit or drag the playhead to where you want the zoom to stop. Adjust the scale to make it bigger and it will create a new keyframe. The software figures out whats in between these two keyframes and animates it- in this case, a zoom.
