If you mean text superimposed on video, either -

* Start with a Text Preset with Transparent background (shown as grey chequerboard) on a track above the video, or

* If you have a coloured background, make this transparent by opening the Properties tab, locating the Background Colour panel and sliding the triangle alongside the vertical rectangle to the bottom. You can also change the setting in the "A" (alpha) box to zero.

That is an interesting way of phrasing a question to completely disguise what you want to know.

If it's on a flat surface you can do it. Like changing the text on a sign or something.
If the surface moves (like text on the side of a bus) it's a little harder, but still doable.
So it gets a lot harder when the surface is not flat, and yet moving.

But wait, there was a tutorial to celebrate the then new bump map thing (Vegas 4?) where some text was laid over the water rolling in over a piece of shore. Rather neat, but maybe not what you were looking for.

I agree.... Although I am sure it was not deliberate. On another forum I belong to - there is a community called "Explaining things really badly".

In which some of us may talk about explanations in an unhelpful way, that is, trying to explain things, or talking about explaining things, but not doing it well - that is, the explaining - but sometimes doing it well when we're talking about explanations rather than actually explaining, except that even when we're doing it well the aim is to do it badly at a later date, except perhaps outside of this forum, in an advice kind of way. I think. Hang on, I've got it in a book somewhere.

This post would most definitely fall into that category.

Grazie.... it you really do want a link to it I will send you an invite. It's not really all that impressive... good for a little laugh every now an then.

ill try agen then,

can u crop images and such ( text) whatever, in the third dimension?(rather than up and down)?

Cropping images is pretty much by definition a 2 dimensional operation. They have no 3rd dimension to manipulate.

However, that being said, you can use 3D track motion to move the images around in a 3 dimensional space, and you can zoom in on that space to show only part of the image. Is this what you are asking?

3d track motion??

Do you have the full version of Vegas or do you have the MovieStudio version?
