There's also a word of warning here - the fps filter (which gets auto-inserted with -r) has a tendency to buffer the duplicated frames between two input frames. This can cause large memory spikes if your input has low fps (or is generated from JPEGs with large time difference), since frames between two input frames will be generated and then sent to the output in a single operation, spiking memory usage. |

Which ffmpeg version are you using? This hasn't been the case since 2012. Both input and output -r are effected through fftools and not libs.
