A transcoding service is described that is capable of utilizing the excess capacity of the computing resources of a service provider. The customer of the transcoding service can submit a bid price for completing the transcodes. As long as the specified price exceeds the fluctuating price of the unused resource instances, the transcoding service will execute the job on the unused instance(s). If the price of the unused resource instances exceeds the customer's bid, the transcoding process stops. The transcoding service may pause the transcoding when the dynamically fluctuating price of the unused resource exceeds the customer's bid and then resume when the price falls back down. Users can specify constraints for transcoding, such as timeframes during which the transcode must be completed, a total price for completing transcoding or priorities of the media files. The system can automatically optimize the utilization of the resource instances according to the constraints.
