Split n Join - User's Guide


Mac application Split n Join



Installing and uninstalling Split n Join

Please read the README file that comes with the application.


Using Split n Join

Split n Join utilizes four split components from SplitMe, another commercial Mac application we have developed.  This User's Guide does not cover these components.  Please refer to SplitMe User's Guide for


  • SplitMovie
  • SplitZip
  • SplitImg1
  • SplitImg2


A. JoinMovie

Clicking on the JoinMovie button at the main screen, you will see a drop file box to the right.  Drag and drop movie files here.  Supported multimedia formats include AVI, Divx, DV, MOV, MP4, WMV and more, depending on your Mac OS version and QuickTime components installed in your system.

After dragging and dropping multimedia files on the drop box, you will have movie files listed with file names, durations, data sizes, resolutions and frame rates.  Pay attention to resolutions and frame rates.  Although Split n Join can combine movies with different dimensions and frame rates, we highly recommend that you use movie clips with the same properties (resolution and FPS).  Also, note that the order by which movie clips are listed matters.  JoinMovie will simply append the second movie clip to the first one and the third one to the combined one and on and on.  Therefore, if necessary, adjsut the order by selecting a movie and dragging it up or down.  Finally, if you are ready to combine movie clips, click on the Join button at the top.

And Split n Join will instantly combine all the movie clips into one and display it in a separate movie screen.  If you have used movie clips with different resolutions, the dimensions of the movie screen will be adjusted to the largest resolution of all.  Consequently, some frames should be put in a letter box.

You are not even half-way through.  Anyway, if you are happy with what you see on the movie screen, choose Save As under File to create a QuickTime movie.  Remember that the resulting QuickTime movie is not completely self-contained.  Try opening the saved movie with QuickTime and see Properties.  All the QuickTime movies should be listed with audio and video tracks, many of which (appended movies) are actually referenced with relative links.  You can use the saved movie as long as all the components stay where they were.  In other words, if at least one of the components goes missing, changing its location, then the entire QuickTime movie will become useless.  Therefore, we recommend that you import the saved QuickTime movie back to Split n Join and export it to make the movie self-contained (to make all the tracks multiplexed).

In order to export a saved movie, choose Import under File.  Select the last saved file.  After making sure that a movie is shown in the movie screen, which suggests that no audio/video track is missing, choose Export under File.  (If even one track is missing, then Split n Join won't be able to open the saved movie.  Neither can QuickTime.)  Unless no track is missing, you will see the QuickTime movie export window.  Name the movie and click on the Options button if necessary to configure export settings.  Finally, click on the Save button to compress the movie.  This final step can take quite some time, even hours or days for slow machines or due to lack of video memory.  And you will end up with a self-contained, multiplexed QuickTime movie.


B. JoinAudio

JoinAudio works pretty much in the same way that JoinMovie does.  To begin with, drag and drop audio files on to the drop box to the right.  Supported audio formats include AAC, AIFF, MP3, M4A, OGG, WAVE and more, depending on the OS version and the QuickTime components installed in your system.  The media lists shows file names, audio durations, data sizes, audio compressors, sample rates and sample depths.  Again, pay attention to sample rates and sample depths.  Preferrably, you want to import all audio tracks with the same sample rate and depth.  Audio compressors are less important, though.  If shown in the media list, any audio clip should be decoded accordingly.

Next, just as before, click on the Join button at the top.  And Split n Join will instantly display a small, separate audio player.  You can test the combined audio clip by pressing the play button.  If it looks acceptable, then choose Save As under File to save this work as a QuickTime audio file.

Furthermore, import the saved audio file back to Split n Join.  Then choose Export under File to re-compress the Quicktime audio file.
