Tests have shown the following:
A bitrate of 500 kbit/s offers sufficient quality for subtitling.
A bitrate of 1000 kbit/s offers superb quality for subtitling.
However it is always better to choose a bitrate that is as high as possible to
provide best possible quality. Please note that for higher bitrates the processor of
the PC must be very fast. A 2.5GHz Pentium 4 PC will only work up to 2000
kbit/s.
