Merge two or more images, music tracks, movies, and documents into a single file. Organize the order of the files and select between the manual and automatic modes. Work with PDF, RTF, TXT, MP4, MP3, AIFF, MOV, M4V, MP4, BMP, TIFF, PNG, JPG, JPEG, GIF, and other formats.

Gelatin is a very handy system utility that lets you merge or join different files together. It supports quite a few different formats, including PDF, RTF, MOV, M4V MP3, MP4, and JPG, among others. The application has a drop zone where you can drag the files that you want to merge together. This interface works like a charm and it makes the app incredibly easy to operate. You simply need to drag two or more files, and then the application will ask you where you want to save the merged file and its name.

Unfortunately, you will also need to enter the extension of the file, because it isn't detected automatically. If you don't enter it, the application will return an error and the files will not be merged.

From the Preferences window, you can change the behavior of the application slightly. For instance, you can set it to automatically quit and beep when files are done merging and you can also set a default location for your files to be saved and even a name for them.

I tested the app by joining two MP3 files together. The process was smooth and rather fast after I figured out that I had to include the .MP3 extension for it the app to work.

Just tried a re-install as suggested. The same error. Can someone please clarify what is meant in this article by "adding the extension manually." ? It does most file types fine, but not MP4s - just shutdown once I have dragged them onto the interface and once I click on the play button. Any help is appreciated.

Hello. I am trying to join two mp4 files but having the same error message come up. Would you mind explaining how you 'add the extension manually'? As I can't see any way to do that... Cheers!
