Infoseite // green screen / chroma ask



Frage von sadira:


Hello, I would like to propose a person from a cut film, with no blue or green screen

because the camera is static, would be my idea, until only the background to film, and then the person
but it would have comparatively möglichsein a kind to make, and only represent what is happening in Film 1 is different than in Film 2
zb rest green and hide

I hope this is somehow understandable way (-;

Once again the (Keyword)> Differenzkey (After Effects). But the fact is that a Chromakey (green or blue, because some units in skin color) or even a Lumakey (strongly lighted white wall with "zebra") to simplify the matter and bring a better result. For chroma Lumakey is like a skirt around the foreground subject to be avoided (blue or green halo, "Highlight", "edge"). The simplest is that the background is somewhat removed next. The Chromakey is due to the 4:2:0 Farbsamplings of Consumer codecs was not very clean contours have. As always synonymous, and in any case, a Nachbarbeitung necessary.

A tip for Differenzkey: The background should be completely static, no clouds, leaves minimal light or synonymous changes.
