What is AEC file?

The AEC file has been categorized as Video Files. It was designed by MAXON. In addition to this file, the Video Files category includes 546 related files. Cinema 4D After Effects Composition appears on 2 operating systems as a functional file. These systems consist of Mac OS, Windows, although it may occasionally be found on another system, it will be non-functional. It is recommended to use Adobe After Effects to handle this file. This is a program created by Adobe Systems Incorporated. This file type can also be opened by 1 other programs.

How to open AEC file?

The main problem with Cinema 4D After Effects Composition is that the AEC file is incorrectly associated with programs. This is manifested by the fact that AEC files open in unusual applications or do not have an assigned program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the AEC file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Adobe After Effects

The first step is to check if the computer has the Adobe After Effects program installed. The easiest method is to use the system search engine by entering the program name Adobe After Effects in it. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support AEC files.

Programs to open AEC file

Remember to download programs supporting AEC files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Adobe After Effects with AEC files

If, despite the installed application, the AEC file does not start in the Adobe After Effects application, you must create a file association. This option is available from the level of Properties of a specific file available in the context menu. Information about the file and the program that the file is associated with are available here. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the AEC file with the Adobe After Effects program.

Step 3. Update Adobe After Effects to the latest version

The fault may also lie with the Adobe After Effects program, it is possible that Cinema 4D After Effects Composition requires a newer version of the program. This can be done using the application (if it provides such options) or from the Adobe Systems Incorporated website and install the latest version.

Step 4. Check for the following problems with the AEC file

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. Usually this applies to AEC files downloaded from the Internet in case the download did not finish properly. The only repair option is to download the file again.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file AEC or the program directory. Sometimes virus-infected AEC files cannot be recovered, so make a backup in advance.
This can happen especially when the program is dynamically developed and the structure of the AEC files changes over time. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular AEC file corruption. The easiest way is to restore the file from a backup, if there is one, or contact MAXON
The program indicates that the file is encrypted or corrupted. The encrypted AEC files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. Copying the AEC file to another location will fix the problem.
This can happen on a file that does not support multiple access. In this case, the AEC file is blocked by the first application to open it. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Some anti-virus or backup software may occupy the AEC file for a certain period of time. If this does not work either, restart the device.
