It's easy to create a speed-ramp effect using the time-remap function within Adobe Premiere.

Start with a new sequence that contains a single clip.

Move over to the video track 1 header in your sequence and hold down the mouse button at the top of the video track to resize it so it's taller.

Do the same for the audio track, but from the bottom of the track.

Then right click in the blue area of the V1 clip segment.

From the contextual menu Choose Clip Keyframes / Time Remapping / Speed.

Move the playhead indicator to a point where you want your clip to start to slow down.

Then hold down the command key and click on the white speed graph line.

This will add a keyframe.

Then move the playhead indicator to where you want your clip to speed back up.

Hold down the command key again and click on the white line to add a second keyframe.

Now park the selection tool over the white line between the two keyframes.

Drag the line downward to the desired speed.

In this example, I'll adjust the section to 50%.

In doing so, the clip segment will become longer because of the speed change.

Okay, so right now the speed change would be abrupt.

To fix this, drag the first keyframe to the left.  

This will create a ramp.

Do the same for the second keyframe, but drag to the right.

If the first half of the keyframe stays selected, this will allow you to smooth out the graph.

It's important to note that when working with the time remap graph, Adobe Premiere will not slow down the audio for you.

So it can get a bit tricky if you need to make it appear that the audio is in sync.

In this example, you can see right here within the audio waveform where he jumps off and then lands on the ramp.

In an attempt to fix this, I'll press the C key to activate the razor tool.

Then by holding down the alt key, you can cut just the audio section.

Then press the V key to re-activate the select tool.

Now move the sections of audio so they are in sync with the jump takeoff and landing.

To get rid of these gap areas, press the R key to activate the rate-stretch tool.

Grab the edges of new audio segment and stretch it so it covers the gaps.

Okay, check it out!

You should now have the basics of using the time-remap function and stretch tool within Adobe Premiere.
