Whew! Have not seen this problem before. Have been using Premiere since Ver 3.
I am in a project where I am dropping Jpeg images on the time line and creating a slideshow.
I am doing lots of motion with keyframes on scale., position etc .
When I render the project some images disappear and another image appears several times in their place.
Here is the link to the uncompleted video :
Notice the image of the bride and groom at front of the car keeps repeating itself, whereas other images were placed in the timeline.
Help would be appreciated. I have redone the project 4 times.
Open the image in Photoshop or other image editing application, and resave it.
BTW, this issue should be fixed in Premiere Pro CS5.5. Users of Premiere Pro CS5 will need to use the workaround that Colin mentioned.
