What PC software offers speeding up video & sound together at 20x+? I'm new to video editing, and I'm trying to find the right software to fit my needs.  I am interesting in creating videos where I want to speed up both the video and the sound together to rates of over 20x.

For example, here is the link to a YouTube video that is similiar to the style movie that I want to make.  This person used iMovie to create this video.

I started with the standard GoPro Studio, but whenever you speed up video with that program, the sound is lost.

I then moved to CyberLink Power Director, and with that program, the sound is not able to be sped up over 8x I believe when attached to the video.

I heard about Sony Video Studio, but it looks like you can't speed up the video past 4x in that program.

I do not want to break the sound apart from the video and try an pair it back up after speed up both the sound and video individually.  I also do not want to speed up the video/sound a small around, render the video, and then speed it up again, as that create a lot of redundant work.

Ideally, I would like to find the PC version of something like iMovie that has this capability.
I think Premiere can easily reach 80x. And you can go past that putting sequences one into the other
