The project is made of several components: The format option may be needed for raw input files.īy default ffmpeg tries to convert as losslessly as possible: It uses the same audio and video parameters for the outputs as the one specified for the inputs. * To force the frame rate of the input file (valid for raw formats only) to 1 fps and the frame rate of the output file to 24 fps:įfmpeg -r 1 -i input.m2v -r 24 output.avi * To force the frame rate of the output file to 24 fps: * To set the video bitrate of the output file to 64kbit/s: Each occurrence is then applied to the next input or output file. Therefore, order is important, and you can have the same option on the command line multiple times. You usually only have to specify the target bitrate you want.Īs a general rule, options are applied to the next specified file.

The command line interface is designed to be intuitive, in the sense that ffmpeg tries to figure out all parameters that can possibly be derived automatically. It can also convert between arbitrary sample rates and resize video on the fly with a high quality polyphase filter.
