When importing an AVI file, After Effects including the recent After Effects CC sometimes returns the error “Unable to open that file. File uses an unsupported compression format.” You may be confused about this cause Adobe claims After Effects does support import AVI files. Well, in order to get AVI and After Effects to play nicley, the codec that a particular file uses must be installed on the computer. If you receive an error message or the video does not display correctly, you may need to install the codec used by the file. However, AVI can contain various video codecs. It’s difficult for you to find and install the codec.
In fact, there is another easy option to use all AVI files and AE without problems. The quick workaround is to transcode AVI to After Effects supported MPEG (the most compatible video format for AE) file format and then transfer the converted AVI videos to AE for editing.
To convert AVI files to AE, we need to get some help from third-party software.
