Uploading to Wakepics question

While i am laid up with my ACL injury i have taken on the role as Filmer/Editor in our crew so i have my first video and i want to upload to Wakepics and i have tried compressing the crap out of it and i just can't get it to work. I followed Kung-Fu wakes instructions which really helped (thanks) but it is still 13.5 mb is that just too large? I don't want to sacrifice all the quality just to compress it smaller, any help would be appreciated
