Clip Mac Command Line

  • ImageMagick is a free command line program which works in a Unix Shell, so can be used via Mac OS X's Terminal program, but can also be run on Windows via a separate executable. It reads in hundreds of type of image formats, but only writes out MPEG or animated GIF.
  • Mac CLI is a set of utilities that simplifies that. Mac CLI is basically a set of developer-friendly utilities in one package with easy-to-remember commands. Mac CLI can handle basic stuff like.

Press Command + Control + Shift + 3. This method works exactly like the one above, except the screenshot does not immediately create a file. Instead, the image is saved to the clipboard, the same temporary storage area where your computer remembers the text that you have copied. For Windows and Mac, there is an executable installer than runs this script; for Linux you need to run the script yourself at the command line. If you are willing to install to the default location in the system and set up the IMOD environment for all users in the default way, then you can use the installers on Windows and Mac, and install on.

  • 2Methods for Creating a Movie from an Image Sequence

About

On this page I've listed a few options which can help you take a sequence of numbered image files, each representing a 'frame', and convert that into a movie file.

NOTE: In all cases, it's pretty much assumed that your image sequence is put in its own separate folder and the image names should be end with numbers as per the examples below:

  • 'frame000.png', 'frame001.png', 'frame002.png', etc
  • 'my_movie_001.jpg', 'my_movie_002.png', 'my_movie_003.png', etc


Methods for Creating a Movie from an Image Sequence

Option 1: QuickTime Pro...... ($30 for Mac and Window)

QuickTime 7 works on Windows and Mac (not Unix) and it costs ~$30 to unlock the 'Pro' version which can be used to modify movies. Instructions to install QuickTimePro are here. Once installed you must make sure you have a sequence of (same sized) images in a numbered sequence (eg: img000.tif, img002.tif, ... img099.tif). Within QuickTime click: File > Open Image Sequence and select the first one. From here you can chose frame rate and it will save to a huge .mov file, but after saved you can go File > Export to save to a number of different compressed formats. Read more about these export options [[[QuickTime|here]]. Even though it costs $30, this is my preferred choice for because I like having lots of export options.


Option 2: ImageJ...... (free and cross-platform)

Clip Mac Command Line

ImageJ uses Java so is cross platform (Windows, Mac OSX and Unix). ImageJ/'Fiji' (a fuller featured version) can reads and writes many image formats, but only writes out one type of movie format - and that is AVI. Often AVI is all you'll want though (especially if you want a PowerPoint movie) and the instructions are as follows:

  1. Copy all the images/frames you want in a single directory with nothing else, and make sure they are in alphabetical order. For example: 'frame000.jpg', 'frame001.jpg', etc.
  2. Open ImageJ.
  3. Click File > Import > Image Sequence, navigate to the desired directory and click Select. There are some nice options here for scaling etc.
  4. Click File > Save As > AVI..., select your frames per second (25 is good if you have many frames) and save you AVI.

There are no options for AVI quality, but this is still very effective if you happen to have ImageJ/Fiji installed.


Option 3: VirtualDub...... (free, but Windows only)

VirtualDub is for Windows only and was designed for creating and editing AVI files. Once you've installed the program from here, just do the following:

  1. Open VirtualDub then click File > Open, then select the first image in the sequence.
  2. Click Video > Frame Rate, to change the frame rate (once loaded).
  3. Click File > Save as AVI to save.


Option 4: ImageMagick.... (free, command line and cross-platform)

ImageMagick is a free command line program which works in a Unix Shell, so can be used via Mac OS X's Terminal program, but can also be run on Windows via a separate executable. It reads in hundreds of type of image formats, but only writes out MPEG or animated GIF. It is also tricky to get conversions to work, so if you're not comfortable or unfamiliar with command lines I suggest you skip this option! To install ImageMagick go to the imagemagick download page. If using a Mac, the easiest way to install ImageMagick is to install 'MacPorts', then run 'sudo port install ImageMagick'. For Unix, ImageMagick may already be installed, and you can type 'convert' into the command line to check. Once installed, you should put all your frames into a separate directory, restart a new shell and then run this command:

Actually I've never had this work for me, because ImageMagick has many nasty dependencies. If that doesn't work the following line creates an animated GIF (yuck):

NOTE: A similar command line toolset you can install is FFmpeg


Option 5: Adobe Photoshop.... (costly, Windows and Mac)

Although expensive, Adobe Photoshop is a program many people may have already.

From CS3, Photoshop allows you to create movies/animations. Prior to that ImageReady was used for this.

For CC and later see: https://helpx.adobe.com/photoshop/how-to/make-animated-gif.html

For CS3 to CC use:

  1. Go: File > Scripts > Load Files into Stacks... (This option will add all your image in as one file with separate layers) and add all the images you want in the animation.
  2. Open the Animation Palette under: Window > Animation.
  3. Click on the Flyout Menu on top right corner of the animation window and select Make Frames from Layers.
    NOTE: If your frames are backwards click the bottom left icon to of the animation window get into 'frame animation mode', select all the square frames then click the flyout again and reverse frames.
  4. Adjust the timing of each frame by selecting the 0 sec. on the frame.
  5. Go: File > Export > Render Video. Among the many options you can save as a movie for Flv, IPhone, IPod, Quick Time, MPEG4 and so on. I recommend using compression type 'H.264'.

Edit in iMovie on iPhone or iPad

After you add video clips and photos to the timeline of your project, you can make a clip longer or shorter, change the sequence of clips, or split a clip into two separate clips.

Make a clip shorter or longer

You can trim a video clip or a photo so it appears for a shorter or longer period of time in your project.

  1. With your project open, tap the video clip or photo in the timeline. A yellow highlight appears around the selected clip.
  2. To zoom in on the clip, pinch open in the center of the timeline. When you zoom in, you can see more detail in the clip, which can make it easier to edit.
  3. Drag the beginning or end of the clip to make the clip shorter or longer:
    • To make the clip longer, drag the edge of the clip away from the center of the clip.
    • To make the clip shorter, drag the edge of the clip towards the center of the clip.

If you can't drag the edge of the clip, there might not be additional video at the beginning or end of that clip. For example, if you added a video clip that’s 20 seconds long, you can’t make it longer than 20 seconds. It might also mean the clip is at the shortest length allowed by iMovie, which is 0.3 seconds. If you still want to change the duration of a clip, you can try slowing down or speeding up the clip.

Change the sequence of clips

You can change the sequence of clips in the timeline to change when a particular clip appears in your movie. With your project open, touch and hold the video clip or photo in the timeline until it rises off the timeline, then drag and release where you'd like the clip to appear in your project.

Split a clip into two separate clips

When you split a clip, you can adjust the duration of each section, remove unwanted sections, or add different titles to each section.

  1. Scroll in the timeline to position the playhead (the white line) where you want to split the clip.
  2. If necessary, pinch open in the center of the timeline to zoom in on the clip.
  3. Tap the clip, tap the actions button , then tap Split. Or tap the clip, then swipe down over the playhead on the clip, as if you were slicing through the clip with your finger.

iMovie places a None transition (also known as a cut) between the two newly created clips. You can change this transition to a cross-dissolve or other transition.

If you can't drag the edge of the clip, it means there is no additional video at the beginning or end of that clip. For example, if you added a video clip that’s 20 seconds long, you can’t make it longer than 20 seconds. It might also mean the clip is at the shortest length allowed by iMovie, which is 0.1 seconds. If you still want to change the duration of a clip, try slowing down or speeding up the clip

Add or remove frames with the clip trimmer

For more precise editing, you can use the clip trimmer to add or remove individual frames from a video clip. You can also see how much of your clip is being used in your movie.

  1. In the timeline, select the clip you want to trim.
  2. Choose Window > Show Clip Trimmer. The selected clip appears in the clip trimmer, above the timeline. The part of the clip that is visible in your movie appears between the two white lines, and the parts of your clip that don't appear in your movie are dimmed and outside the white lines.
  3. Hover your pointer over the line at the beginning or end of the clip until the clip trim tool appears, then make the clip longer or shorter:
    • To make the clip longer by adding frames, drag away from the center of the clip.
    • To make the clip shorter by removing frames, drag toward the center of the clip.

Mac Command Line Tutorial

You can use a different portion of the same clip while maintaining its length in the project:

  1. In the clip trimmer, hover your pointer over the clip until the clip trimmer tool appears.
  2. Drag the selected portion of the clip left or right.
  3. To close the clip trimmer, Press Return.

Change the sequence of clips

You can change the sequence of clips in the timeline to change when a particular clip appears in your movie. With your project open, click the video clip or photo in the timeline, then drag the clip left or right depending on where you want the clip to appear in your movie:

  • If you want the clip to appear earlier, drag the video clip to the left, then release.
  • If you want the clip to appear later, drag the video clip to the right, then release.

You can also move multiple clips at once:

  1. Hold the Command key as you click each clip you want to select, drag a selection rectangle around the clips, or hold the Shift key as you click each clip.
  2. Drag the clips to a new location in the timeline.

Split a clip into two separate clips

When you split a clip, you can adjust the duration of each section, remove unwanted sections, or add different titles to each section.

  1. Scroll in the timeline to position the playhead (the white line) where you want to split the clip.
  2. If necessary, choose View > Zoom In or press Command–Plus sign (+) to zoom in on the clip.
  3. To split the clip, choose Modify > Split Clip or press Command–B .

After you split the clip, add a transition like a cross-dissolve between the clips.
