Unfortunately, you have posted to the Premiere forum. This is for the precursor to PrPro, which has its own forum. I'm sure that Jeff, or Curt will move this over to that forum.
Now, there are two places that one would set the FPS. The first will be in the Sequence Preset. If one chooses a Desktop Preset, they can then change nearly all of the settings. What is the FPS in your Sequence?
Next, when doing Exports to many formats, one can also set the FPS. What was chosen in your case.
PS - what sort of display will handle 3500x600 material? Just curious.
I do not why it changed but check the Interprete Footage in the Project Window and set it to the right Frame Rate.
Also check if your sequence setting is set to 25 fps, that is if you are on PAL.
