What kind of source material is this? Interlaced? If is is interlaced, you have to tell the encoder. If you don't tell the encoder, you either get very bad quality or you need a very high bitrate. > Given those caveats, can someone explain how I > can programmatically set the bit_rate? Do you mean "how do I set the bitrate"? Since you answered it above, I don't understand the question. Or do you mean "what value should I choose for birate"? If you ask the question, I consider it an indication that you actually want constant quantiser instead. Using a bitrate makes mostly sense if you have a known upper limit.
