| 28 | | || Slices: || -slices || 4, 6, 9, 12, 16, 24, 30 || Each frame is split into this number of slices. This affects multithreading performance, as well as filesize: Increasing the number of slices might speed up performance, but also increases the filesize. || |
| 29 | | || Error correction/detection: || -slicecrc || 0, 1 || 0=off, 1=on. Enabling this option adds CRC information to each slice. This makes it possible for a decoder to detect errors in the bitstream, rather than blindly decoding a broken slice. || |

It requires encoding the file twice, though: The 1st pass is to analyze the video source data and logging the results, and the 2nd pass uses this previously gathered information to achieve a higher compression ratio.

| 31 | | || Multi-pass logfile: || -passlogfile || a filename prefix || This is the prefix of the logfile used for storing the information gathered during previous passes in multi-pass encoding mode.
