You need to open the Motion JPEG B compressor component, use ImageCodecSetSettings to configure it with progressive settings, then pass the component instance in the codec parameter for CompressSequenceBegin.

To create a settings handle for progressive settings that you can pass to ImageCodecSetSettings, the simplest thing is to write a small app to generate it. Open the Motion JPEG B compressor component, call ImageCodecRequestSettings, set "Number of fields" to One in the dialog that comes up, and then save a copy of the resulting handle.
