In 5 steps you'll be able to zoom during video recording with your lovely N9, I also tested it, it works fine :

1- Enable developer mode (Settings> Security> Developer Mode) if not already done.

2- Download the file camera.conf

3- Open Terminal and enable root acces :
-devel-su
-password : rootme

4- Copy the downloaded file in the etc directory:
cp/home/user/MyDocs/camera.conf/etc/camera.conf

5- Restart the device.
/sbin/reboot

Note:
-It can now zoom both with the top bar (like the pictures) and with the volume rockers.
-To remove this tweak just delete the file by repeating the procedure from step 2 to step 5 and type this command:
rm/etc/camera.conf
