A technique for managing the production, post-production and distribution of audio-visual projects permits accurate management of production values and thereby allow accurate and measurable reproduction and control. Test signal data is used to assist the operator in insuring the levels are set to the intended display characteristics in the event that factors such as creative lighting or applied effects affect the desired look of the scene. The test signal data may encompass elements that determine resolution, White level, Black level, Grey steps, Frequency response and linearity as well as sound parameters. Chroma channels may exhibit similar signals including a bar pattern that can be used to insure the best colorimetry is maintained. Standard signals may also improve compositing and cross media transfers without extraordinary efforts to match production values.
