Processing video data with a combination of one or more operations, such as special effects, on a general-purpose computer may be improved by enabling one or more operations to access and process multiple samples of video data from other operations that introduce latencies for each request for data. Operations that introduce latencies include, for example, hardware for decompression and compression, network interfaces, and file systems. Because a computer program to implement the operations may be executed on several different general-purpose platforms, exact specifications of available hardware are not known in advance. For each operation, a computer program determines the available system memory and an amount of data that can be processed by each operation used in a composition or portion of a composition while sharing the available memory with other operations. Available system memory is allocated among the operations being used.
