Rendering Older Image

I’m using Blender 6.86 on Mac Pro. I’m having issues rendering. I rendered a video image perfectly, but when I came back to file and moved camera to new angle it displayed the previously rendered version. I’ve spent hours trying everything I could think of including online searches. No matter what I change prior to rendering, the image is still the original graphic. This has to be something simple to fix, but I can’t find the answer. Any ideas?

Have you anything loaded in the video sequence editor or compositor and have them enabled in the Render / Post Processing settings. These would overide your scene rendering.

The one thing you didn’t do was post a link to your blend file so other users could check for the solution
