Does speeding up video affect audio?

Yes. Audio pitch changes with speed — sped-up audio sounds higher, slowed audio sounds lower. For tutorial speed-ups at 1.5x-2x, speech usually remains understandable.

Can I create slow motion from normal video?

Yes, but quality depends on the original frame rate. A 60fps video slowed to 0.5x produces smooth 30fps slow motion. A 30fps video slowed to 0.5x becomes choppy 15fps. Higher original frame rates produce better slow motion.
