![]() ![]() This has a highly undesirable effect on edge quality.ĭetail: Avoid high levels of detail regardless of camera type if detail is necessary to achieve the image quality desired, then the best choice is to use the chroma key Edge Some lower-cost lenses can exhibit chromatic aberration - colored halos - around edge transitions in certain Lens: Select a camera lens based on the set size and production needs. The better the noise performance of the camera - the better the Most obvious in dark areas of a developed chroma key and can be very difficult to remove without compromising key quality. Keying as the chroma levels in a normal video image are much lower than the luma levels - as a result, the chroma information contains proportionately more noise. Image noise has a significant effect on chroma Imager/Sensor Noise: Noise is always present in the video image but can be minimized by choice of sensor type and gain settings. These edges will appear as bright or dark key halos, which cannot be removed without compromising overall key quality. Detail-enhanced edges are undesirable inĬhroma keying. Resolution imagers can produce great results in normal video productions, but rely on relatively high-detail settings to enhance image edges. This is critical for an excellent final result. Resolution: Cameras naturally vary in performance the ideal camera has a high-resolution imager with very low noise. That the chroma background reads as an even signal without variation. Look at the camera output on a waveform/vectorscope and ensure
