wanting to pan jpg images

[Douglas Spotted eagle]

If you can only get vertical pans, is your horizontal locked off?
You’ve got to keep the target area inside the limits of the image. Vegas isn’t changing the image, merely cropping what’s on the sides or top of the image. “Coloring outside the lines” means you’ll have pillar boxes or letter boxes.

You mean the jpeg is much larger than your project don’t you? I’m not sure that matching the output aspect will help you unless you are trying to see the entire jpeg at once within your video. If you are shrinking the video by dragging a corner, you simply need to drag in the opposite direction to expand it. You must expand it to zoom in. If you shrink it too much, it will become too small to fill the screen. That will reveal black “space” behind the image. That is probably why you think you are seeing black bars.

Thanks DSE and Bob,

I don’t have the aspect ration locked. I should have been more precise.

I guess the problem is I’m having a heck of a time understanding how the pan and crop tool works. When I try to zoom into an image by expanding the box, the image often does no longer fits the entire viewing area.

I’m trying to get a bit of a “Ken Burns effect” where I could start zoomed in on a part of the image and slowly reveal more of it as I zoom out. OR… pan from a part of an image to another.

also, I’m finding difficult to relate to the window in pan/crop tool (with the “F”). I thought it would simply contain what will be seen on screen but apparently not.

If someone could also point me to an article that describes how to interpret it, that would be great!

Think about it. If you are zooming in, why would the viewing area continue to show the entire image? You are zooming in so that you can see more detail. You can only see more detail if things get larger. When the image gets larger, you can no longer see the entire image within the fixed size of a TV, projector, etc. The increase in size is also what gives you the ability to pan.

I don’t have the aspect ration locked.

You should if you want the image to fit the aspect of your project. Otherwise whatever is outside the project aspect will be black (or show the track below)

You don’t zoom in by expanding the box. You zoom in by making the box smaller. You zoom out by expanding the box and if you zoom out too far you’ll see black edges.

It’s quite simple: “F” is the camera Frame. Think of it as a virtual Viewfinder on your video camera. If the image completely fills the “F” it will fill the screen. If the image is smaller than the “F” there will be black on the screen where the image is not.

If you think of it in terms of camera movements, by making the “F” area larger you are pulling back to take in more area making the image smaller. By making the “F” smaller, you are pushing in and filling the viewfinder will a smaller amount of the image.

Does that help?

If the jpeg’s aspect ratio does not match the project’s, forcing it to fit the project will distort the jpeg image. This matters if the intent is to zoom and pan the jpeg. If that is the case, the jpeg will probably be larger than the viewing area, and it will not leave black borders unless the viewing area moves beyond the jpeg boundary.

Good point. I left out an important step. If you have Maintain Aspect enabled, AND then right-click the Frame and select “Match Output Aspect” you are guaranteed that the image fills the frame, cropping off any areas outside the project aspect. It’s the Match Output Aspect step that I left out. (sorry)

Just to be clear, Maintain Aspect ensures that any resizing because of cropping is done quality in both the width and height. Maintain Aspect actually prevents an image from being distorted.

Yes John, Thanks!

This helps tremendously. I’ll give it another try armed with this new information….
