Thanks for your reply, Jeff. Yes, I use Vegas and yes, I had thought of exporting the project directly from there to .mp4 at first, but in that case I’ll get only the actual main video. In Architect I had also added a selectable menu and an additional small video. I had hoped there was an easy way to get the whole “caboodle” on the iPad as one file, but perhaps I have to be content with loading the two videos separately.
Thank you again for your response.
Nina
