How to speed up more than 400% without dragging more footage in?

Hi everyone 👋. Hopefully this will be a nice simple one for all you knowledgeable Vegas Pro folk out there 🤞. The video I'm trying to create is nice and simple. It's simply my partner and I building a gingerbread house. What I want to do is speed up bits of footage where nothing much is happening. The video will then be talking > speeded up footage > talking > speeded up footage and so forth...

The clips below A are where we are talking. B is footage I want speeding up. My problem is this, using Ctrl+Drag Left only allows a max of 400%. You see, I'd like to speed it up more than this, maybe 500 - 600%. I've tried using a velocity envelope on the clip to get more speed and as much as it achieves what I want, I don't seem to be able to find a way of it ONLY speeding up the section of footage in question. The velocity envelope keeps dragging more and more footage past the point of where I've split the clip and it's impossible to work out where the split was.

So my question is, is there any way of speeding clip B up by more than 400% without dragging footage from the next clip (same file)? Almost a way of telling the velocity envelope that I just want this section of footage sped up and nothing more? 😁

Thanks for any help that you can give me,

Scott (Vegas Pro 20)

Add more points to your velocity envelope to bring it back to 100 percent.

@Seggons Hi, you could try-

Right click on your trimmed clip/s - Create Subclip.
Right click+drag the Subclip from Project Media window on top of the orig on the timeline - Add As Takes.
Right click on that event - Switches - Trim event to include all frames.
Right click - Add Velocity envelope.

When you alter the speed with the envelope it will auto trim the event but not add unwanted footage.

Right click - Take - to change or delete the chosen take on the timeline.

This has just blown my mind. I always thought that the velocity envelope was just a bar that could be dragged up and down. I didn't realise until today that points could be added along it so thank you for teaching me that 👍😃.

This is just what I was after, thanks @Gid 👌.

@Seggons Keep also in mind that using velocity envelopes only changes the speed of video and NOT the speed of audio. With the stretching method (to max 400%) audio is also speed up.
