QuickTime for Simple Video Editing
You probably know that QuickTime is fantastic for recording you, or your screen, but did you know it's also fantastic for quick and easy editing?
Most of the time all we want to do is a very simple edit, no need for fancy transitions, titles, and all that jazz, will if that's the case QuickTime is all you need. If all you want to do is any/all of the following:
Trim the start/end point of a video or audio clip
Remove sections of a video (split then delete)
Join several video clips together
Separate one bigger video clip into several smaller clips
Change the format of a clip eg mp4 to m4v, or mp4 to aac et cetera...
Edited audio can be saved it to Music (iTunes) as AAC (Apple's version of an MP3) using the Export option, if you really need it to be an MP3, Music can convert audio files to MP3 if you need it to.
Editing Video is wonderfully simple, you can trim the video just as you a would audio, (which incidentally is exactly the same on any iOS device, same conventions). But where it really rocketh is in it's accuracy with splitting and deleting bits of video, or moving them around.
Just choose View > Show Clips to reveal a simple editing timeline at the bottom, click to select it (it will have a yellow outline) then move to the section of the video you want to split, you can even nudge the split point frame by frame using the arrow keys.
View > Show Clips
This opens an editing timeline for splitting, trimming, combining...
View > Show Audio Track
This allows you to see where the quiet parts of the track are...
Combine several clips into one, just drag and drop...
Edit video by splitting
View > Split Clip
Or just press Command + Y to split wherever the video is playing
Cut up your video into sections
Now you can move, delete, trim any of the sections
