Problem rendering quality

Hi guys
I have a problem with the rendering quality ( video ) it’s a bit blur and low quality when it’s a sequence of pictures , here is some pics ( there is only one with good quality , I found it in the end of rendering )

Hard to see any difference. Try png instead of jpg maybe?

Hi again
I will try to save with png this time, the difference is between the first and the other pictures , (wood and vase) the quality is lower , some blur
Thank you
