Why does my After Effects have [filename] the blockbrackets with the filename in the Timeline?
I reckon it is something to do with save files or the other thing?
Thanks in Advanced
Click on the Name panel right above the footage and see what happens.
As Dave hinted, you can either view the layer name or the source name, and you can pick which by clicking the column heading. The brackets are an indicator of which you're seeing if the layer name and the source name are the same.
Thank you very much
