I have been having great difficulty creating a still image slideshow with audio in Adobe Premiere Pro CS6. I am usually using H.264 codec with vimeo's SD preset. Every time I export the images either have a serious degredation in quality or some other inexplicable error occurs such as this one:
The slide show is fine until it reaches this image at which point the background which should be black becomes this odd, pixelated gray. There is one other image where this also occurs. I have no idea what I am doing wrong.
Are you applying 'Lighting Effects' in your Timeline?
Lighting Effects effect
Nope definitely not. Maybe I did inadvertently, but I kind of doubt it.
Try tweaking your H.264 bitrate & pass number settings.
Are you updated to CS6.0.5?
