Troubleshooting Problems Opening MJP2 Files


Common Problems Opening MJP2 Files

Adobe Premiere Pro CC is Not Installed

When you double-click your MJP2 file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Usually, this is because you do not have Adobe Premiere Pro CC for %%os%% installed. Your operating system cannot associate your MJP2 with Adobe Premiere Pro CC, so double-clicking the file won't work.


Tip: Another MJP2-related program can be selected to open the file by clicking "Show Apps" and finding the application.


Outdated Adobe Premiere Pro CC

Occasionally, you might have an outdated version of Adobe Premiere Pro CC installed that's incompatible with your Motion JPEG 2000 Video type. If you've got the wrong version of Adobe Premiere Pro CC installed, you'll need to install the correct version. Most of the time your Motion JPEG 2000 Video file was created by a newer Adobe Premiere Pro CC than what you have installed.


Tip: Right-clicking on your MJP2, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.


Ultimately, most of the difficulties opening MJP2 files are due to having the wrong version of Adobe Premiere Pro CC installed.


Other Causes of MJP2 File Opening Problems

Assuming you have the right Adobe Premiere Pro CC version installed, other problems can prevent you from opening MJP2 files. There can be external issues inside of %%os%% that are causing these errors when opening MJP2s. These other problems include (listed in order from most to least common):

  • Invalid MJP2 file references in the Windows Registry (the "phonebook" of the Windows Operating System)
  • Unintentional removal of the description of the MJP2 file inside the Windows Registry
  • Adobe Premiere Pro CC or another MJP2 application experienced a flawed installation
  • Your MJP2 file is corrupted (issues with your Motion JPEG 2000 Video file itself)
  • Your MJP2 has adversely impacted by malware
  • Drivers associated with MJP2 software need to be updated
  • Windows cannot load your Motion JPEG 2000 Video file due to insufficient resources (eg. RAM)
