NIH has accepted videos as post-submission materials for many years (NOT-OD-12-141). Our original guidance required videos to be embedded in .pdf files. Technology changes have made that practice more difficult. Effective immediately (NOT-OD-20-061), post-submission videos do not need to be embedded in .pdf files. Acceptable formats for videos are .mp4, .mov, .avi, and .wmv. All other aspects of our video policy remain unchanged.
