Cinema 4d output animation


Hello, everyone,
when i trying to make animation in one file and get one video file in “animation” format, everything is fine, looks nice.
I’m selling my animation, the quality must be high, almost without loss and some pages do not accept in this format, don’t accept such a single “animation” file as i rendered.
But when I trying another method - to do image sequence (.png). My special effects (moving wind, fog and etc.) somewhere disappears.
Can you explain that?
Thank you!
