I don’t edit video often, which means it feels different each time I try. I last wrote about cropping on a Mac in 2012. It felt different (but easier) this time.

Downloading the file from youtube

I entered the original youtube URL into http://en.savefrom.net. Then I downloaded the mp4 file.

Opening the video in iMovie

  1. Open iMovie
  2. New Project
  3. No theme
  4. Name project
  5. Import Media > navigate to the mp4

Crop the video

  1. In the thumbnails view, select the beginning of where you wan the video to start.
  2. Drag to where you want the video to end.
  3. Adjust as needed
  4. Play the video in the preview to ensure it is right.

Export the video

  1. File
  2. Share > File
  3. Next
  4. Save to location
  5. Wait until Mac pops up message that export was successful

cropping video fast for dummies on a mac

Two years ago, I wrote about cropping video fast for dummies on Windows.  I now need to do the basically same thing on the Mac.  This time is a little simpler as I only need one continuous segment cropped.  And I have more experience.  I’ve done it once before 🙂 on a different operating system.  However, I still don’t have any special software.

Where I started

The original video is 2 minutes and 44 seconds.  I want to get a 5 second or so video of the robot shooting a basket.

How I did it

  1. Learned that I do have video editing software – iMovie – that came on the Mac.
  2. Use ClipNabber to download youtube video.  Had to click “clipnabber classic” to get to the download screen as the first screen is about some Mac software to download.  As I don’t do this often, I don’t feel the need to download anything.  This downloaded the clip as an .mp4 file.
  3. Downloaded Squared to convert from mp4 to something iMovie can import.  (Squared beta lets you download directly from youtube, but I’ve already downloaded it.).  Open mp4 in it and choose export to DV>  Conversion took less than a minute.
  4. In iMovie, file > import > movies
  5. iMovie automatically splits the video into short thumbnails.  Drag the one(s) you want to the top.  It’s cool because you can select a range so this serves as a rough cropping.  You can also join clips that way.
  6. Click on point of subclip you want to start and choose split.  Repeat for end of subclip.
  7. Right click video and choose detach audio.  Select the purple audio track and select cut.
  8. Share > Export movie

Converting to Flash

It was requested I provide a Flash version of my 4 seconds of video.  There is software you can download that does this, but I didn’t want to download something (trial version) that I’d only use once.  Another option is to upload it to youtube.  I went with the youtube option.  Then back to ClipNabber to download as flv (flash.)

How did it work?

This process was better than the Windows way (without a real editor.)  iMovie is impressive.

The final product

The completed video does show what I wanted.  It was easier to get rid of the sound this time too which is good because I won’t control the viewer’s machines this time.
