I haven't looked at it yet, but you shouldn't use single-pass bitrate mode. Use either 2-pass bitrate or single-pass quantizer.

edit-

Hooo boy.. your video is a good example of why not to use smart bob anymore. I'd like to see how leakkerneldeint performs in that clip.

Here, quick setup:

- Download LeakKernelDeint
- Extract to avisynth plugins folder
- Add this code to your script

Code:

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\leakkerneldeint.dll")
avisource("blah.avi")
complementparity()
#LeakKernelBob(order=1,threshold=0) 
LeakKernelBob(order=1,threshold=10,sharp=true,twoway=true,map=false)

Actually, if you could do me this favour I'd really appreciate it.. Could you upload that same clip without any deinterlacing and at a high bitrate? Xvid Q1 would be good. I'd like to do some deinterlacing tests on it.

Thanks for that. Cheesy

Used that instead of smart bob and got better results (most noticably as far as on screen text is concerned at least). Here's the insane quality output (2-pass) test file. The XviD version is over 190megs, so I'll upload it tonight after work.

Wow that's 10 times better. Shocked

Only one problem remains.. that strange dotted line at the top. It looks like a capture issue since the pd_zero clip had it, too. You should look into that since it may be a defect with the capture card.

Well, that's been on ALL of my capture cards (and other vids I've seen taken on a capture card directly by other people), so I can't do much about it. It's certainly not a defect in the card tho.

Glad the clip is more to standard Wink

Thanks for the help again. Cheesy

Ok, then add this near the end of your script:

Crop(0,2,0,0)
Addborders(0,2,0,0)

Or maybe

converttoyuy2()
Crop(0,1,0,0)
Addborders(0,1,0,0)
converttoyv12()

Nice one. I've added it so it looks like this:

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\leakkerneldeint.dll")
avisource("cod2.avi")
complementparity()
Crop(0,2,0,0)
Addborders(0,2,0,0)
#LeakKernelBob(order=1,threshold=0)
LeakKernelBob(order=1,threshold=10,sharp=true,twoway=true,map=false)

Will test it out later on. Smiley

Thanks again.

I edited my post, you should probably use this one instead:

converttoyuy2()
Crop(0,1,0,0)
Addborders(0,1,0,0)
converttoyv12()

There's only 1 pixel line in your video that's useless, it's just that you can't crop by 1 in YV12 colorspace. So by converting to yuy2 first, you can, and then convert it back to yv12 for the encoder.

There shouldn't be any color loss since YV12 (4:2:0) is a subset of YuY2 (4:2:2). But I'm not an expert on this, I just compared it with two instances of vdub and I don't see any difference in color.

i haven't watched the video, but that may be because the card is not expecting odd dominant video.

If you haven't watched it yet, how do you know if it's "dominant" Wink

Also, can I apply such filters WITHOUT capturing? I need to use the card for still shots, but with the interlacing being a bugger, all fast paced action will have the lines in them. Can I apply any filters without capturing to get the same de-interlaced effect?

The only way to get progressive is if the console, game, and capture card support it.

I suggest trying out mvbob(), this thing is pretty kick ass and should get some acceptable results. Check this thread to learn how to get it setup: http://speeddemosarchive.com/yabb/YaBB.pl?board=other;action=display;num=1149210661

Got a couple more PAL S-Video samples uploaded for youto double check for quality. I tried that mvbob() but I - personally - didn't notice any difference and the compression time (even on my P4 HT 3.4Ghz rig) took FARRRRR too long in comparison.

http://www.gamerguides.co.uk/samples/fight_night_sample.avi (17.87 Megs)
http://www.gamerguides.co.uk/samples/pgr3_sample.avi (16.89 Megs)

This one is a decent PS2 PAL Composite sample:

http://www.gamerguides.co.uk/samples/god_of_war_sample.avi (16.26 Megs)

The part at the top that you don't like has been removed (thanks to your help) and - I think - they look absolutely stunning (especially the Fight Night 3 Xbox 360 sample).

Hehe, I'm re-encoding my God of War run and the 3 and a half hours of footage took about 5 days to encode the HQ version with an Athlon X2 4400.

I think you need a bit of a trained eye to fully appreciate mvbob. But that's ok, when I introduced mvbob in this forum I said it's only for the hardcore quality enthusiasts. Wink

Anyways, your quality test gets an A+ in my opinion. Fight Night and PGR3 look amazing. The God of War sample looks pretty good.
