Movie render queue and sequencer do not render correctly

Hi everyone, I’m trying to render a scene which contains some glass material (car head light), but the outcome didn’t match the preview in my viewport.

This is the scene in my viewport:

Here is a frame captured by high res screen shot: As you can see, the headlight begins to disappear as I increase screenshot size multiplier.

Here is a frame captured by the movie render queue: And the sequencer:

Anyone knows what the problem is?

when you increase multiply more than 1 time, there is a pop out message, warning you that the additional effect will be gone!

so how can i fix it?

I just want the headlight to appear in my final render
