I’m also new to Vegas, and I have learned a lot from this forum group.
I also have the full version and I have learned another way to change the speed of your clips. First put your clip (event) on the timeline. Then you can hold down the CTRL key and drag the end of the clip. If you drag it in, it will speed it up. If you drag it out, it will slow it down.
The only problem is that when I do this, I’m not really sure of the percentage that I’m changing.
I’m not very familiar with the velocity envelope, but if it is better, I want to learn more.
