Have you tried rescaling the image to the final export dimensions before importing into PR?
Thank you for answering so promptly Harm.
I have left the PS image the size it is as I wish to zoom in to the details and trace the route taken in our travels. Or do you mean that I should just try exporting the time line to bluray to see if that image is blurred?
Make sure Default scale to Frame Size in the Preference is off.
If its not the image will come in at 100% and you are zooming beyond 100% which means bluriness.
Thank you Ann. The scale to frame size is off. When the timeline is not playing, the image is perfect. It only goes fuzzy when playing.
Is your playback resolution set to full?
Bingo Harm. I feel such an idiot. I have wasted many hours trying different things. Now its perfect.
Thank you very much. It never occurred to me. I must have disturbed the settings somehow.
Now I will sleep easily tonight.
