View Full Version : Encode with WMP12 quality deinterlacing?

I recently bought MXC Volumes 1 and 2 and I've been trying to rip them with good quality for a while now. If I demux the VOB and play the M2V back with WMP12, it looks great. WMP12 apparently has an on the fly deinterlacing. However, when I use any software to convert it to H.264, it always ends up looking crappy, no matter the software, deinterlacing, or bitrate. This is really frustrating. If it can play back good quality, why can't I convert it to good quality? If someone could help me out with getting the video do deinterlace with good quality, that would be great.

Upload a small 10 second source M2V sample - one showing steady movement - to a 3rd party upload site such as SendSpace or MediaFire so we can have a look. I don't really think that WMP can do a better job than a good AviSynth deinterlacer. You might also tell us what software programs you've tried already.

Thanks for the response. When I get home, I'll upload a 10 second clip of the source video. What program is good for splicing 10 seconds out of an MPG without recompression?
I've been using the deinterlacing from the built in video encoders, but those haven't been working so well. Specifically handbrake's. But last night I put it through VirtualDub's deinterlacer and the straight uncompressed deinterlaced video looks great. However, whenever I convert it to h.264 at around 1000kbps, it blocks like crazy. When I move the bitrate above 2000kbps, it starts to look better, but h.264 always seems to block it whether I use an x264 gui or handbrake. I just want a clean image like I see from the straight deinterlaced AVI, and I would think that 1500kbps + the right settings would be enough, but I don't know how to make it so the compression blocks don't appear. So maybe the problem is a combination of the deinterlacers and the settings I've been using for encoding? But I'll upload the clip so you can check it out

Okay, uploaded two clips. One is with fast motion and the other is a place with some motion where the blocking becomes very noticeable.

Here's my most recent result. If I deinterlace with VirtualDub, it looks great. The result is a 35GB AVI. So then I try and reencode that, and it seems at about 3000kbps with x264 is where the blocks finally disappear and the quality is finally good and there are no blocks during movement. So I've upload my results, the first clip is at 3000kbps and looks great, the second one is at 1000kbps and looks abysmal. Could you show me your results @ 1000kbps and 15000kbps two pass? 1500kbps is the highest I think I'd want to go, but even that is pretty high for standard definition.

Thanks a lot.

I am afraid WMP12 uses hardware deinterlacing, which cannot be used when you are encoding.

As far as I can tell, that video (the original) is not interlaced. There's a ton of aliasing going on; it looks like it was badly deinterlaced or something. Some sections do look slightly interlaced; maybe it needs a pass with decomb.Here's my most recent result. If I deinterlace with VirtualDub, it looks great. The result is a 35GB AVI.

http://www.mediafire.com/?ktyfmngnzyzThat's a ridiculously high-motion intro sequence with tons of cuts. It requires more bits than the rest of the episode. Testing just on that will give much different results from testing on the whole episode.
