Hi Phyllis, Andrew My script was just a proof of concept, can cinelerra use external tools for proxy file creation or not. The answer is Yes. > how does Cinelerra work with this proxy file and switch back and forth to the "real" file As I remember, the user must create a proxy file with external script, and the next step is to tell cinelerra to use proxy. It won't recreate proxy files because they already exist.
