Ultra fast motion in Sony Vegas 10.0e?

I know about the control button feature and the velocity envelope and playback rate, but is there a way to make my video even faster?

I'm doing timelapse and would love to have 60-100x+ faster than real time. Thanks!

Apply both, save it as a veg file, start a new project, import the veg file and repeat both methods as needed.

What do you mean import the Vegas file into another new Vegas file? What if I have many other cuts in my timeline that I don't want to apply this fast motion to? Thanks.

Re: Ultra fast motion in Sony Vegas 10.0e?

Start a new instance of Vegas, copy/paste the desired clips from the existing project to the new one, do the speed-up tricks to them, save the project, delete those clips, import the saved veg, repeat, get the speed up to the desired amount, save it again, close this project, go back to the existing one, import the saved sped up veg file and drop it on the timeline.
FYI, this technique is called "nesting".

How to get up to 1440fps in Vegas

if a max limit of 1440fps (60x24fps or 48x30fps) is good enough, the following will work... but you can't go any faster without doing what Mike suggested.

1) render the clip you want speeding up to an image-sequence (which go up to 120fps)
2) import the image-sequence, assign desired frame-rate
3) playback rate (4x)
4) velocity envelope (3x)

note: when importing the image-sequence, do a quick compare of the video and image-sequence versions with the scopes; sometimes Vegas handles bitmaps weirdly (ie; you may need to put a computer-to-studio filter on the image-sequence to have it match the original; not likely but figured i should mention)

You may be better off exporting an image sequence. Under scripting. That many speedups, interpolations, and renders is going to take its toll on quality. An image sequence will be full-quality frames.

Re: Ultra fast motion in Sony Vegas 10.0e?

NOTE: In the newer versions of Vegas, outputting to an image sequence is under File - Render As instead of via scripting.

You also get more options than just jpg or png.

Re: Ultra fast motion in Sony Vegas 10.0e?

Does anyone know how to set the time step when rendering an image sequence in Pro 10? I only want to capture one or two frames per second, but Vegas wants to create 30 stills per second.

Re: Ultra fast motion in Sony Vegas 10.0e?

I can see a couple of ways to handle this:

1. Go back to using a script

2. Speed up the clip, export, and then revert it back.

Re: Ultra fast motion in Sony Vegas 10.0e?

I found that changing the frame rate in project properties sets the time step. For my current project I set the frame rate to 2 and I ended up with two two stills per second when rendering the image sequence. Not sure if Vegas will accept fractional frame rates if you want less than 1 frame per second.
