I’m having the exact same problem.
I’m exporting animation from Premiere Pro as 29fps MPEG-2 and the quality of the export is fine/the same as within Premiere. However, as soon as I import into Encore there are artifacts, shaking and an overall fuzzyness/blurred quality.
I’ve tried all different types of exporting, but it seems that the problem is with Encore since the exported Premiere files look fine. As soon as they are imported, the quality degrades. This is all
