Batch ogg vorbis transcode

What I'm trying to do is simply make this command

-shell
find . -name "*flac" -exec oggenc -q 7 {} \;

spit the oggs out into whatever folder that I choose. I've tried just putting ~/vorbis at the end of the command, but I get a predicate error:

find: possible unquoted pattern after predicate `-execdir'?

I've been through the "find manpage", and I understand that the {} at the end of -q 7 is there to find flac files. So this is throwing me for a loop. Anyone know what I have to add to that command so I can output oggs into chosen folder? Thanks for reading and helping. By the way, I did try:

-shell
find . -name "*flac" -exec oggenc -q 7 ~/vorbis {} \;

but that only spit the oggs into the folder with the flacs. Not a ~/vorbis folder. I'm trying to keep folder name and structure put output it into a folder of my choosing (~/vorbis). And I 'm not asking for a full script. I'm just simply asking for somebody to explain how I can get what I'm trying to achieve. Thank you!
