It is definitely easier that way, and we can make a lot of simplifying assumptions. I would still consider having a placeholder image to cover for the possibility that there might be parts where no slide or screen recording is shown. But we mi= ght make it a policy to always show something. WDYT? > > -- > Ricardo > Best regards, g_bor
