Super Slow Motion ... Sound

I have some video off of a Go Pro Hero .. I shot it at 60 FPS .. I can drag the timeline out to a point .. then it just stops .. I want to make 3 seconds of video last a minute. How do I go about doing that ?
Also when making slow motion video how do I get the sound to be more low toned rather than the buzzy high pitched I have now .. My old video software had a box that I could click and it fixed the sound .. How do I do it in Sony Movie Studio 10 HD? Thanks .. K

"I want to make 3 seconds of video last a minute. "

That wish of yours is not grounded in reality. If you were able to accomplish this through multiple regenerations in Vegas, quite frankly it would look like crap.

Get yourself a camera that shoots 600 frames per second and you will be in the right ballpark. You might find a couple of surplus models available from NASA.

Vegas Movie Studio (and Vegas Pro) only let you stretch out a video to a max of 4 times its original length. In Vegas Pro there are a few additional tricks to let you stretch it out slower, but in Vegas Movie Studio I think your only option is to do this:

1. Stretch 3 seconds out to 4x its length (12 seconds long now)
2. Render this to a new file.
3. Bring the rendered file into VMS and stretch it out 4x (48 seconds long now).
4. Repeat as needed.

However, as Musicvid pointed out, don't expect it to look that good. VMS will mainly be repeating frames to stretch out the video, or creating the intermediate frames by blending two adjacent frames. You can right click on the clip, select "Properties", then try out the different "Resample" options to see what works best for you.

For example, assume your video has frames A-B-C-D-E, and you stretched it out to just 2x its original length.
With "resample" disabled, your resulting video would consist of the following frames: A-A-B-B-C-C-D-D-E-E etc
With "resample" enabled, your resulting video would consist of the following frames: A-AB-B-BC-C-CD-D-DE-E-EF etc, where the "AB" frames are a blend of the A and B frames.

For the audio, right click on the audio clip and select "Properties". In the lower part of the Audio Event tab, where it says "Time stretch / pitch shift", locate the box that is labeled "Method" and select a method. If VMS has the "elastique" method, that's probably better. You might only have "Classic" -- if so select it.

Once you've selected a method for pitch shifting, locate the box that says "Lock to stretch" and tick it. You should now get slowed down audio.

BINGO .. That's what I needed for the Video.

The Audio is still not right. In Pinnacle Studio HD they have a box I can un-check so that it doesn't try and fix the pitch. I hate using Pinnacle and would like to figure out a way to get it don with Movie Studio

Bad slow no audio

Good slow mo audio

Not sure why you posted links to a video that has it audience settings on 'private' only.

In 'preferences' of Vegas, you can uncheck the audio pitch fix for slow motion.

Super smooth slow motion.
