How to join AVI video files on Mac? The problem is that you don't have any ideas about getting started, right? Well, it's a good thing that you have landed on this post. This post aims to present 3 free options in joining movies together in a fast and user-friendly manner. On this account, this resource includes the benefits and drawbacks of each option so that you would be able to find the right one that will fit exactly your needs.

The three options are using Terminal, through the use of QuickTime and editing with Filmora for Mac.

Let's take a closer look at the three.

Option 1: Join AVI With TERMINAL

Let's start with the first option which basically entails the use of Terminal commands. Although it may be quite daunting for you, users can expect that it would be worthy of time in the long run. In order to make the first option possible, all it takes is to work in an individual movie file, stick the files together and sort through the header section to come up with a smooth performance.

To begin with the use of Terminal, You have to modify the directory of the locations of your movie files. The first thing you need to is to open a Terminal located in Apps. You should do this alongside modifying the directory command. There are two ways on how you can do it. The first is to type out the path manually and the second one is to drop the folder to the Terminal window before you click enter.

Next is to stick the movie files together. In this method, the second movie file will be taken. With this, you have to put the bytes on the end part of the initial file and go over it again until such time that all you work on all the files. With the use of Terminal, opt for pot down; make use of the cat which is located on the word concentrate command.

The videos will stick together with the cat command. There's nothing to worry about mixing up because they will be sorted in order. One of the best parts here is that you are free to add a number of files as many as you wish. However, you have to keep in mind that it could also lead to problems with a long list of files.

Also, you should know how to rebuild the header file so that the second book will be easily read. This is to make sure that all of the video contents are played and not just the first part. This is where the use of a certain program called Mencoder steps in. You can have it from a website called mplayerhq where in the only requirement is the binary for Terminal. After installing Mencoder, you can now rebuild the header of the avi file.

All you have to do is to paste mencoder -forceidx -oac copy -ovc copy output.avi -o output_final.avi; into the terminal.

No need to worry about incorrect file because that's the job of the last line from the cat command. There you have it- the first option, as simple as that!

  • Pros: The pros of this method include the freedom to stick files as many as you want. Also, there's no mixing up of files. You're always good to go! It is also very simple.
  • Cons: What's not so good is that too many files could cause some problems. Plus there's more of a command you have to work on.

Option 2: Join AVI By Using QuickTime

If you are not pretty sure about the use of Terminal, QuickTime Player 7 is a great alternative.

First, open up QuickTime from the Utility folder. Have the first movie opened before moving the scrubber to the far right portion of the window.

After that, drag and drop the second movie into QuickTime. Do the same with the scrubber then repeat. After compiling your move file, proceed to File Save As and opt for a self-contained movie. This app will then compile your movie and release it out.

  • Pros: The best thing about this method is that it is novice user-friendly as there are no hefty commands that you have to deal with. This makes it very well rated by many customers. So, if you are not so crystal clear with the first method, you can make use of this one.
  • Cons: The only drawback of this method is that you don't have so much control of the final movie file specs.

Option 3: Join AVI With Filmora for Mac

With its simple and clear interface, Filmora for Mac makes join AVI video much easier for normal users. But your video would have a watermark if you're using free verison.

Step1: Import AVI videos you want to join together

Step2: Simply drag-and-drop these videos to timeline in order

Step3: Click Export button to save these AVI videos as one

As you have found out, each option listed to join Avi videos on your Mac has its own chief benefits and simple drawbacks. Whatever is your option, you have to make sure that you are clear with all the details in order to make things work out as you assume. But all in all, both of these options are great options that can make you on the go with those videos.

An Alternative Way to Join Avi Videos on Mac for Free with iMovie

The Macintosh family of personal computers is pretty unique – designed, manufactured, and sold by Apple Inc., a lot of Macs have programs and software developed only for them, not compatible with Windows. iMovie can be considered one of them – it is a preinstalled video editing application developed by Apple Inc. for macOS, iOS, and iPadOS devices.

On iMovie web-page we read: “Turn your videos into movie magic… you can enjoy your videos like never before”. When it comes to professional editing, everything is entirely possible, but in this article we are going to limit ourselves with merging AVI videos for free with iMovie. AVI is a multimedia container format introduced by Microsoft, so, joining videos comes hand in hand with joining Microsoft and Mac in this case, which, without doubt, is going to be interesting…

So, it’s pretty simple: if you hold down Shift and select the clips that need to join together to highlight them,



then go to Modify and select Join Clips, you will see the clips are merged as one!
