Error occurred while creating project
January 31st, 2009
Message text:
After Effects: AEGP Plugin AAF: Error occurred while creating project.
Message interpretation:
The program could not add a footage item to the project during import.
Possible causes:
The error is quite misleading and can crop up on a number of occasions. In the given example, an MPEG-based source material was imported without success and triggered this message. AAF refers to advanced audio formats, which in this case would possibly mean embedded audio in a video file. Such files are regularly generated when using modern digital photo and video cameras and transfering the data on the file system level without additional capture procedures. Within the file, often multiple data streams are stored, which can include multiple audio channel as multiplexed or unmultiplexed streams plus any number of extra streams for timecodes or metadata. If these streams do not adhere to a given order, e.g. audio is recorded on channels 3 and 4, not on 1 and 2, After Effects may not be able to recogize or decode them properly.
Another case is presented, when you do not transfer the whole content via a specific file manger associated with the camera. This regularly happens to users with P2 systems, that require to use a specific helper program to transfer the MXF files correctly in the order they are stored. This means, that the entire folders in which they are organized need to be transfered, including any auxiliary files also stored in those. This not only ensures retaining all the metadata, but also continuity, if multiple files are linked to present one shot/ take.
Resolution or workaround:
Use the file management and conversion tools bundled with your camera to transcode the files and transfer them to your computer. Also make sure to check your camera and choose a more compatible set of defaults for it to avoid these problems in the future.
