Performance of a set of video processing devices in a flexible architecture such as flexible hardware, software or both, can be predicted by analyzing and storing information about the performance of individual video processing devices. An editor will specify a combination of operations to be performed, which are associated with a set of video processing devices. Given this set of video processing device to be used, the performance characteristics of individual video processing devices in the set are accessed. For each frame, a total performance characteristic of the set of video processing devices is determined. This determination can be made by combining the performance characteristics of the individual video processing devices according to a combination of operations performed by the set of video processing devices to produce data for each frame. The performance characteristic may include latency, processing time and/or memory bandwidth. The total performance characteristic may be compared to a threshold. According to this comparison, it can be determined whether the set of video processing devices can produce each frame in real time.
