Lighting effects not exporting smoothly

[jessevantrigt]

Dear all,

Iam working on this ad with a lighting effect on the background, but as soon as i export it I see lines of the effect in the clip. (see example)

Is this a rendering problem?

An export Problem?

Can anybody help me with this?

Kind regards,

You may need to export with a higher bit depth codec, your still looks like an 8bit.

Try one of the DNxHD 10 bit codecs to see if that is better.
