Another one of my small time guides. This time I was chilling on some grapes!
Things you can do with Quicktime Pro:
1: Rotate video: Movies shot in portrait mode look great while filming them but look awful once they are on the PC. How does one rotate? Quicktime Pro. Just open the video, hit Command+J and select the video track at the top. Then just hit the rotate buttons and you're done! No need for rendering and all that.
2: Add your watermark. Just create a Jpeg with whatever watermark you want. Black, will reveal, and white will block. So if you want video playing in a text "Goobi", just type out Goobi in photoshop in black and save it. Just remember the video crops to the black edges, so it's best to add a 1 px stroke to the outline of the image.
3: Extract audio from a video: Again, in movie properties, select the soundtrack, and hit Extract. Then save that.
4: Add chapters to a movie: There's a nice little guide prepared by apple. Just search for "creating chapters" in the help. You then get a nice little drop down list to select your chapters. Useful for music concerts and such.
5: Add audio to track: Open your video track. Then open your audio track. Do a command+A, and then Command+C to copy the audio track. Highlight the video track and hit Edit > Add to Movie. Add to movie and Scale makes your audio fit the video by slowing it down. You can do it the other way as well, that is, add video to the audio track.
