    13 The native encoder has the advantage of not requiring an external library and both encoders should provide a similar output.
     13The native encoder has the advantage of not requiring an external library. Both encoders should provide a similar output, but for lower bitrates/quality (e.g. 1000 kBit/s for 720p content), xvid will deliver better quality than mpeg4.

    1515The default FourCC stored in an MPEG-4-coded file will be `FMP4`. If you want a different FourCC, use the `-vtag` option. E.g., `-vtag xvid` will force the FourCC `xvid` to be stored as the video FourCC rather than the default.

     30There is rarely a need to use `-qscale:v 1`. Note that if you choose it, libxvid will take much more space than the same video compressed with the native mpeg4 encoder.
