General :: Rsync Files Recursively But Place In One Remote Directory?

i would like to find and backup all *.mp4 files from /Pictures and its sub-directories and move them to a single directory on a remote. I can find and move the files but I don't want the directory structure...just the files to be placed in the remote directory.

To find my files I use

rsync -r -a -v -e "ssh -l user" --delete --include '*/' --include '*.mp4' --exclude '*' /home/drew/Pictures/ remoteserver:/Users/drew/mp4

but this creates all the subdirectories

I also tried

find ~/Pictures -name "*.mp4" -exec rsync -r -a -v -e "ssh -l user" --delete {} remote:/Users/drew/mp4 ;

This works but takes forever
