It does make logical sense that packaging the (adaptive) interlacing and (adaptive) deinterlacing into the encoder should make it work better than externally - but it's more complexity: more tuning in the encoder; more work in the decoder. Has anyone ever done it?

x264's interlaced encoding is inherently less efficient than its progressive encoding, so it is probably better to deinterlace an interlaced source before encoding rather than use interlaced mode.
2Bdecided, is this the bottom line or do you still maintain that it gives "better quality/lower bitrates" in h264? If yes, what other encoder than x264 are you refering to?
