Photoview360 rendering model produces different material characteristics rendering a single frame?

For some reason when i save an animation through photoview (saving the bmp files) my materials look different to when i just render one frame??? ive got some example photos attached but i cant work out why it changes the material characteristics when i save the animation through photoview ??

The image where everything looks normal is a single frame render (this is what i want).

The image that is really white and the poles have a transparacy to them is a frame from multiple frames saved during an animation rendering (this is not what i want).

Thanks for the help!
