IMHO, I have two suggestions.
1) Use a video converter to reduce the size somewhat. There are several free video converters/editors available for downloading.
My personal favorite at the moment is Freemake Video Converter (
www.freemake.com/free_video_converter/ ) You will have the option of sub-dividing your clips in the Freemake editor to make them smaller.
2) Upload the segments to Multiupload and make your post in that OCC section.
Hope that helps.
