Have seen the check your filters solution for the "No Formats available with current settings problem". The problem is all filters are shown as off in my V19 project. More than that, the identical project a) worked and works perfectly under V17; b: loading it into a V19 session that has a "renderable" offering, i.e. get a project up which shows all render settings available then simply load the failing project in and still get message. And conversely, opening another project in place of the failing project shows all render settings. There are two somewhat unusual aspects to the failing project: use of reverse and use of Twixtor; however, as noted, V17 doesn't have a problem. (Didn't install V18 so nothing to report.)
