The AEC file extension is used for Cinema 4D After Effects Composition files. It is a native file format used by both Cinema 4D (C4D) and Adobe After Effects (AE). It enables users to transfer 3D scenes and compositions between the two programs with ease and accuracy.
An AEC file contains all of the necessary data for a single After Effects composition, including 3D layers, lights, cameras, effects, plug-ins, blend modes, layer styles and cinema 4D assets. In addition, the file also includes project settings, resolution and frame rate information and any additional information needed to create the 3D composition. AEC files are often used in video production workflows, allowing creative teams to collaborate on shots that use both 3D elements and textured 2D elements.
Similar File Extensions
The Maxon BodyPaint 3D, After Effects CS5.5, and newer versions of both Cinema 4D and After Effects are capable of opening AEC files. When opened in any of these programs, the entire composition state is present in the file. The contents of the file can then be manipulated as desired, such as adjusting settings for objects/layers, editing cameras, or rearranging lights.
AEC files can also be saved in other formats such as Layered Photoshop (.PSD)or Avid Media Composer (.AVI). This allows for additional flexibility when working with AEC files in non-compatible programs by providing access to more options for importing content or saving different formats that work better for specific technologies.
Programs for WINDOWS system
Programs for MAC system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .AEC) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .AEC extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .AEC file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .AEC extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .AEC extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .AEC file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .AEC file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .AEC file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .AEC file) will be extended to the maximum.
It is also good to check
- if the .AEC file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
