I like to incorporate large panorama photos into my HD videos. These are resized down to around 9000 x 1200 pixels, and then I use Magic Motion, Pan and Zoom to slowly pan (a 1920 x 1080 window) across the image.
In PD8 these generated a nice high quality effect with all the detail visible.
In PD10 the effect is, to put it bluntly, rubbish. For a HD output the image quality is worse than SD! I have a suspicion that PD10 is (internally) resizing the full sized image down to 1920 x 1080 and then applying a 16x9 window to the degraded image. How else could PD10 produce such a low quality image?
Any suggestions why PD10 is doing this?
