Bemerkung

This effect may produce different results than Lens Correction (frei0r) although the name may suggest the only difference is the effects library. Lens Correction (frei0r) uses frei0r.lenscorrection, whereas Lens Correction (frei0r) uses avfilter.lenscorrection. There are different options available in each effect.
