I don’t have a 64-bit pc, but I had thought zypper looks after this automatically?
If it were me, I would 1st setup my repositories with OSS, NON-OSS, Update and Packman only per the guidance here: Repositories/11.0 - openSUSE-Community
Setup only 11.0 repositories, and setup ONLY those 4 repositories. ie ONLY OSS, NON-OSS, Update and Packman. No others. None. OK ? (If you need others, they can be installed and immediately removed afterward on an adhoc “as and if” required basis).
Once your repositories are setup, then in a konsole / gnome-terminal simply type “su” to get root permissions and type: zypper install cinelerra kino
and the dependencies and architecture should be automatically sorted for you.
I also recommend you try kdenlive … ie … zypper install kdenlive
If I have this wrong, perhaps a 64-bit user could quickly chime in and correct my mistake. Many thanks!
