There is no information related to the Movie Mode and the supplied arguments. I recommend checking the file you are trying to export, or if you generated the file with another program, then check the software and make sure everything is exported as it is to import it in the Movie Mode. Besides this information, there is nothing else mentioned on Google or any other websites from this category. This appears to be a problem caused by the files you use to create your animations. It's also recommended to check the built-in Help section.
