Re-encoding (short: recoding) means to change the codec which is used to store a film. When a file is recoded, the software decodes the program and encodes it again. Often a more efficient codec is used to create smaller files that can be easily archived. For example, a program is broadcasted as MPEG2 with 4000 kbit/s via DVB and one recodes it into XviD with 1000 kbit/s.

Recoding is the part of post-processing your recordings which is by far the most CPU intense. You're lucky if you can encode in real time into MPEG4 with an older 1.6 GHz processor.

Software Examples
