Good day, everybody.
I like to watch interlaced DVD on computer using bob-deinterlace filter which make picture looks pleasing to the eye.
For me it seems that new codecs provide relatively the same quality of picture with lower bitrates (MPEG2 9mbps = VC-1 Divx x264 3mbps). But as far as I know only VC-1 can encode interlaced video.

GOAL:
To convert interlaced main title (DVD-Video) into interlaced VC-1

ATTEMPTS:
- I've tried FairUse manual regarding VC-1 which describes encoding with VC-1 through ffdshow. I didn't figure out if there is the way to encode interlaced video.
- Got Windows Media Video 9 Series. But it doesn't work with VOB files though it handles *.MPG (renaming VOB to MPG crashes the program)
ACCESSORY GOAL:
May be properly changed all the VOBs into a single MPG will solve the problem? I don't know how to do the conversion.

By the way, Is there any players which plays interlaced VC-1 encoded files using potential of interlaced video (like bob-deinterlacer with MPEG2)?

I don't know about DivX, but other MPEG-4 ASP codecs like XviD and libavcodec support interlaced encoding, and so does x264.

Once you get the video to decode properly (libavcodec's VC-1 decoder and some other filters have problems with interlaced video), there is usually a way to deinterlace by hardware, built-in software filters or ffdshow. If you have a graphics card that supports full VC-1 hardware decoding, like ATI Radeon HD or some NVIDIA G98 chip, MPC-HC and its DXVA filters should work well.

One option is to bob-deinterlace before encoding so you don't need to worry about interlaced encoding and deinterlacing on playback.

I've used Rhozet Carbon to do 30i MPEG-2 to 30i VC-1 with good success, so it's certainly supported.

As for playback, you need to flip on a registry key in WMV9 PowerToy to get 30i to 60p conversion. And it's lovely. I have no explanation why that's so, and thus can only offer my apology :).
