If you are using video creation software (i.e., Windows Movie Maker, Flash, FinalCut, etc.), export (or "publish") the file into a video format (i.e., a file with extension .mov, .avi, .swf, or .mpg).
These options can be selected in most video software. Refer to your software's help guides for details.
Please do not upload your movie workspace file without first exporting or publishing it to a video format - this file is often huge and requires our evaluator to have the same software as you do to view it.
