whenever I try to load images or voices.
I am using Mac mini (4 GB ram).
I am not sure if a better computer could make the operating of the software smoother
Intermittent lagging could be due to the VideoScribe autosave feature kicking in. The autosave will take longer to process, the longer the scribe and can cause the application to freeze temporarily. If you increase the delay of the autosave this will happen less often. You could also turn off the autosave but you must make sure that you regularly save the scribe manually . You can change the autosave frequency by clicking on the cog icon on the projects screen.
