zypper in --no-r openshot
Problem: installed openshot-qt-2.2.0-1.9.noarch obsoletes openshot < 2.2.0 provided by openshot-1.4.3-2.1.noarch
 Solution 1: deinstallation of openshot-qt-2.2.0-1.9.noarch
 Solution 2: do not install openshot-1.4.3-2.1.noarch

It indeed would appear that openshot-qt obsoletes it. In addition, openshot does not even start by default (because of the absence of libmlt6-modules and some ladspa modules, due to my use of --no-recommends). However, openshot-qt does start, even without the extra modules.

Closing for now (since no reply), but feel free to reopen if you think it's really worth having the old one.
