The max upload size for videos is 500MB, which works out to about 15 minutes at HD-quality. You’ll minimize your upload time and still get full HD by uploading MP4/H264 with a bitrate of roughly 5000 kb/s at 1920x1080 pixels (if you upload in a higher quality, your video will be converted and scaled down while we prepare it for playback on the web). If you do not have an editor available to re-output your video at this quality, a number of free tools are available, such as MPEG Streamclip, Handbrake or Miro Web Converter.
