NB: OBE-VoD can only encode to AVC currently. MPEG-2 support is in development.
These settings create generic transport stream types. View the CableLabs or DVB sections for specific information on how to setup these stream types.
Before starting this guide you should be aware of any restrictions (or lack thereof) on AVC Profile and Level. A common restriction is Main Profile at Level 3.0. However, many providers will allow High Profile, which usually provides increased quality.
Note: The settings here are for two pass encodes. If there are time constraints it is possible to not run the first command and delete the "--pass 2" switch in the second encode. It is also not necessary to add any Audio or Muxing options to the first pass. Top Field First is assumed. If you require Bottom Field First replace --tff with:
--bff
Some streams may require a custom SAR. To set SAR add the following option:
--sar X:X

If the entire stream is 25p you can gain significant compression benefits by using fake-interlaced mode. This flags the stream as interlaced, yet encodes it progressively.
