Whenever you watch a tutorial as long as it’s a supported quicktime 7 format you can watch it up to 3x faster. Quicktime 7 (and earlier version) have an option that kind off works like watching something in fast forward with the sound on. The only difference is that the audio doesn’t have distortion from pitch. Meaning, your tutorials don’t sound like they’re being done by Alvin and the Chipmunks. This is great because you can actually understand what the instructor is saying.
