Render Video more darker rather than render picture

Is this only me or others problem too? i want to make animation video and image together combined (compose in other video editor software)

the problem is my video rendered more darker rather than my image rendered (the same location, same number of light, same day time)

i Try render in lossless quality the result still the same with maximum quality the different only the lossless is in PNG image sequence but still darker (same with my mp4)

but when i render only one image the light is true what i want.

Demian Gutberlet is this bug or not?

Hi ElZoel

do you happen to have the setting "Auto Contrast" enabled when rendering the still image? This feature does not work with video rendering (as it would result in unstable contrast between frames and thus to flickering).

Yes i do. hmmm.... oke i'll try it later to render with Auto Contrast OFF, thank you i'll be back with the result soon
