Why from the render to the video the materials reflections are changing?

Hello, I have a problem. It’s my 3rd test with D5 render, I’m really happy for the renderings results, today I tried to render a short sequence in 4k and also Full HD, but i have this problem, the reflections are really different from the render (1st image) and the video ( 2nd image). I just took a screenshoot of the video.

Someone can tell me what’s wrong? maybe i have to work more on the material settings?

Thank you in advance!
