Different Bloom effect live/render

[Miky]

Hello everyone, as you can see in the image attached, there is a difference between bloom effect in live and the rendered one.

The top image is the screenshot took live, better bloom effect, better light, more realistic.
The image bottom is the renderd one, seems like a bad lightsaber
Why there is such a big difference? and how can i setting bloom properly if it change in rendering process? Is there something wrong in what i do??

Thanks

Pretty sure this is because you set the bloom in pixels and it doesn't scale to match the higher resolution of your rendered image. Set the bloom to be bigger and that should help.
