I cannot install cinellera on my Debian Wheezy

got some packages missing (not new enough) - libc6 and libva1
I tried to install them but didn't work.
below were the error messages

What can be done?

First; log in as root to do administrative work, instead of screwing around with sudo.

Second; the dependencies for your desired package are not available in Stable. libc6 is one of the system's core components. Since the package you want requires a newer version, you cannot install it. You might be luck enough to find that package in backports, but most likely you only have two options:
1) Upgrade to Testing.
2) Forget about that package.

4.4 is apparently available for wheezy in the deb-multimedia repo

You could take a risk and --force-all the dpkg line.

# dpkg --force-all -i cinelerra-4.5*.deb

But you really should run a distro with the versioning needed for the result. Having a forced install is unstable, and gets in the way with updates.
