Speeding up Events. I can't do it?

MH_Stevens wrote on 8/22/2007, 9:58 AM
I'm failing tring to speed up an event. I have a 10 minuets take of moving clouds that I want to speed up by about 30 times (3000%) to last 20 seconds. I'm using the velocity envolope and setting the speed to 3000% but event just does not run that fast?

Also I expected compressing an event (shrink with ctrl) to sepeed it up would work but this does not seem to.

What's the correct procedure please.

Render out and then re-render and so on.

That's what I does! Works like a dream!

Mike, are you saying it doesn't work at all? Or are you saying that the fastest you can get with velocity is 300% and the fastest with ctrl-shrinking is 400%? If the latter, that's quite correct and you need to follow Grazie's instruction. If it doesn't do anything at all, then it sounds like you've got some problem with your Vegas installation.

Right. I can get the 400%. Maybe Grazie can explain the render out thing as I have never rendered just part of a project. Do you render it to a file and then re import it to the time-line or can it be done internally? Why the 300/400% limitation?

Thanks

If you combine 400% squish with 300% velocity you get 12x.

I usually do this outside of the current project. Make a new project with just that clip, speed it up, render to a new file, replace the original clip with the new file and repeat as necessary. Then use the final rendered file in the original project.

Why the limitation? Don't ask us. Ask the SONY programmers. *shrug* My guess is that they figured that was sufficient for any reasonable use.

MH? . .hmmm..

"Maybe Grazie can explain the render out thing as I have never rendered just part of a project. "

Maybe he can? Yes, I've asked him and he says yes, . .. hold on . .yes he can!

He says that what he does is to highlight an area and use Render to new track or even . . . hold on . . yes, yes, I see . . he says you can also use render a file and then re-import . .


"Do you render it to a file and then re import it to the time-line or can it be done internally? Why the 300/400% limitation?"

Ah MH wishes to speak to you directly, yeah? OK . .

Hi MH, Grazie here, yes I re-import the file OR do the New Track render option. Is that internal enough? Is this not what you want? You want something more? I can understand that.

"Why the 300/400% limitation?"

Ask SONY. However, my direct question to you, MH, is this: Should this be more? 1000% or 100,000% or should it be infinite? Maybe it should? Put it as a Product suggestion to SONY!

Look, what I understand is that you ARE finding Vegas easy to use and that you are now within that area of activity where you are wanting MORE for Vegas. THAT is a good thing - and I bet Madison would appreciate your wish and enthusiastic attitude.

Regards,

Grazie

Thanks G-man. I'll go give that a try. So I will squish and speed to give 12x and then render to new track 3x to give me 36x. I'm interested to see what quality loss I get with this.

Thanks

No! - When you bring back the render and repeat your 12x you end up with 12x12=144 times ! And so on. You envelope and squish the Render! And then again, if you want 12x144=1,728 times . . .12x1728=20,736 times . . hang it YOU do the math!! LOL!! No, 3x the render will ONLY give you the same file back. You need to do your 12x thing to each progressive render.

Quality? Abso-bloody-marvellous! What do you think? LOL!!! Try a bit of motion blur - FAB!!

Grazie

I thought that was a bloody fast sunset!
Thanks G

I Love doing timelapse sunsets, clouds, etc by speeding up my footage...!

I throw a velocity envelope on my clip and push it to the top of the clip = 300% increase in speed

Open clip Properties and Disable Resample and change Playback rate to 4.000 = 400% increase in speed

Together you have 12x the original speed as mentioned above.

BUT, I also look for the small triangle notches at the top of the clip and put my cursor on the notch closest to the beginning (left side) of the clip and then drag the right hand edge of the clip to that very first notch and the overall clip will be 1/12th the original length, now render that....

Otherwise, I will get a clip with the sunset repeated 4 times really fast....(3X)
When all I really wanted was one sunset super fast (i.e.12x)
If I want to speed it up even more I take the newly rendered clip and do the same steps and it will be 12 x 12 = 144 times the original speed.

Even with "disable resample" I've gotten really nice results, but if you don't check that it will take a whole lot longer to render.
