Hi, George
There is no definitive answer for this, since every festival has its own standards and regulations. My recommendation would be to keep the logos, keep the artwork as you intended (or maybe you could 'hide' them so they're not so apparent, but leaving it clear to the audience what they're watching). I think the majority of the festivals (specially if they're used to dealing with exp.film) won't mind at all...
