Just burned a copy of a previous project fine. Have redone just the last 10 minutes of this "problem project" as a new project and it still starts to pixelate at the exact same place, even though this shortened project (10 min) is now the only project. Then redid all the transitions…same result. (Have been using the same Blu-ray disks for the last few years with no problems.) There is just something wonky about these last few minutes (which have been made the same way as the first part of the video.) Have changed all the variables, one at a time, and still same result. (Even changed the size of the photos in it…some were over 4 mb, so made all of them under 4 mb)…the transition is where things start to break down and pixelate, resulting in even the photos becoming pixelated. The preview seems fine…that's what is weird! No clue…getting quite frustrated. Thinking perhaps moving to Toast 11 might solve the problem? Hate to do that and continue the same! (Using Final Cut Express for making the video.) ANyone else with thoughts???
