# M2VRequantiser(1)

MPEG-2 streams requantization

## NAME

**M2VRequantiser** - MPEG-2 streams requantization

## SYNOPSIS

```
M2VRequantiser
M2VRequantiser <RECOMPRESSION_FACTOR> <inputM2Vsize>
```

## DESCRIPTION

m2vrequantiseris a tool that requantize MPEG-2 streams without recompressing. **M2VRequantiser** accepts raw MPEG2 video data (not VOB) from standard input and writes the recompressed frames to standard output.

m2vrequantiser represents a good replacement for tcrequant, an obsolete utility provided by some versions of the transcode suite.

## OPTIONS

**M2VRequantiser** accepts the raw MPEG2 video data (not VOB) from the standard input and writes the recompressed frames to the standard output.

**M2VRequantiser** takes two arguments. The first one is a floating point value specifying the ratio of compression. The second is the size of the M2V, since the data is streamed to **M2VRequantiser** it cannot know the M2V size.

There isn't any options and the usage is:

```
    $ M2VRequantiser <RECOMPRESSION_FACTOR> <inputM2Vsize>
```

## EXAMPLE

The following command would recompress 'original.m2v', whose size is 1024000 bytes, by a factor of 1.25:

```
    $ M2VRequantiser 1.25 1024000 < original.m2v > requantised.m2v
```
