Thank you for responding. We are trying to migrate away from Webex and have 100's of hours of archived classroom recordings that we're reformatting to MP4. Our intent is to place edited versions of these MP4 classroom recordings into GoToTraining catalogs, then use RevStream for PPV VoD registration and distribution.
It sounds like this will not be possible because (a) catalog and RevStream inclusion is exclusive to My Trainings online recordings created in GoToTraining, and (b) there is no way to convert uploaded MP4 files into the My Trainings GoToTraining online recordings format. Is that correct?
 If my above assumptions are correct, then the only foreseeable workaround is to make GoToTraining online recordings (like normal live presentations), but play back the MP4s on the hosting computer @ full screen resolution for the presentations instead. Essentially use live GoToTraining webinars to bounce MP4 recordings to the My Trainings recording format.
If so, re-rerecording everything again will be a lot of work.
