Project simpson DVD

[mectron]

HI,

1st - I don't know if this question is in the right section, but if if not.. please redirect me :)

I try to rip one of my Simpson Season 2 Episode and i cannot event get the Intro right!!!

I use knot to prepare the project (like in the guide). but since it's only a 23 (or so) minutes episode and there is no way(?) in knot to go lower then 650 mb, i open the Knot's generated avs file in Virtualdub and set range for 1000 frames to do somes tests.

But the only results i can get are:
1. Overall quality at 1100 kbps is look like a 300 kbs encode
2. When i play the original .vod in powerDVD or the .D2V in Knot it play fine.. but when i open the .AVS in VirtualDub the playback is full of what it's seem to be IDCT block....

I did tried various filter (yes i did search the forum) with no success.

I have encode various movies with Knot with great success, including Cartoons (My Lilo & stitch RIP on 1 CD with 2 Audio tracks is 100% perfect).

I dit test with Divx 5.02 and 5.03 with the same results.

Source VOB is NTSC Interlace.

Anyone can help?

PS: Excuse my English (it's not my native language)

Hi and welcome to the forums-

there is no way(?) in knot to go lower then 650 mb

In the Total File Size box over on the right of the Bitrate Tab, you can change it to whatever you want.

Overall quality at 1100 kbps is look like a 300 kbs encode

I don't know why that's happening, as I don't have enough information to figure it out.

the playback is full of what it's seem to be IDCT block....

Based on what you said later, you may be seeing interlacing. Do you see many black horizontal lines, particularly in movement-action scenes? I haven't worked with The Simpsons. Lilo And Stitch was easy, but if The Simpson's was encoded as interlaced, then almost certainly IVTC can fix it. I find it hard to believe that it is truly interlaced. Maybe someone that has worked with it can say. What I would suggest is to Not Force Film (use No Field Operation) in DVD2AVI, put IVTC in your .avs when creating it in GKnot, and then encoding the same 1000 frames in VDub. Then see if that looks better.

Also, for more information on interlacing and IVTC, please read the DVD2AVI-IVTC Tutorial (http://www.doom9.org/ivtc-tut.htm).

Thank's!

I use the Inverse Telecine in Knot and it work great. All the blocks on flat surface are gone (When i open the AVS file in VirtualDub). So now i don't have any block in my Divx Encode.

Now is there a good filter for the Rigning effect? a 3000 Kbps it's perfect, at 2000 it's still enjoyable.. but at 1100 or below it's horrible! I sure i am still doing something wrong... Simpson Cartoon are cheap and don't have a lot of detail (compare to Lilo & Stitch, wich is realy easy to encode a low bit rate).

I have been encoding more then 200 Simpson shows from broadcast source in SVCD Format and the picture is by far better then with DIVX5.

Hi-

Almost there, eh? By "ringing" I'll assume you mean Mosquito Noise. You can use the Spatial-Temporal Filters available in GKnot, or some third Party filters that I think better. You might try the 2DCleaner (spatial-fast), FluxSmooth (spatial-temporal-slower), or Convolution3D (spatial-temporal-slowest). You'll have to put the .dlls in the GKnot folder, load the Plugin and then add the command to your .avs. It's pretty easy once you get the hang of it. You can find them and many others Here (http://www.avisynth.org/index.php?page=Section+3%3A+Filters+and+colorspaces#q3.3). You want the YUY2 filters for the version of AviSynth included in GKnot. But, FluxSmooth is down in the YV12 section, but the download includes both versions.

Ok, a couple things about these dvds, first they aren't exactly easy to rip. I have done them myself and have had a significant amount of problems getting it to look close to the source. For ivt use decomb, I find using this in your avisynth script works best:
LoadPlugin("c:\decomb.dll")
Teleclide(guide=1)
Decimate(cycle=5)
Now, for some more avisynth filters, I find convolution3d using Convolution3d (preset="animeHQ") works well, warpsharp also works well using low values works well like 1 blur pass and depth 10-15. Make sure you are resizing properly, I like neutral bicubic resize to 512 x 384 or 640 x 480 all depends on how much bitrate you want to give it. Alright, now as for setting up the codec, you will need to drop the max quantizer, probably this is a big part of the reason why it looks so bad. Drop you max quant to 8 or even 6. Set the PVE to normal or even to strong. I would use b-frames and gmc as well, I wouldn't use 1/4 pixel since I found that it produced some artifacts when encoding these episodes. I hope my first hand experience with these episodes helps. :)
EDIT: oh yeah, one more thing I forgot, set the rc averaging to 1/2 the # frames.

Thanks BoNz1-Good Post-

He may not be able to take advantage of all your tips as he's encoding through GKnot, I believe. So, no RC Averaging Period or Quant adjustments (maybe he can do that in VDub). He can modify the Telecide setting easily enough (he's already using Decomb as it's the default IVTC in GKnot). And in the Options Tab of GKnot he can make the Pro Features adjustments you suggested. WarpSharp is another (good) Filter available through the link I gave him.

Thank's guys, Can't wait to test it out. I will prepare stuff in Knot, then use Vdub to do the rest.

Will post result tonite (-5 gmt here)

After using all the tips from Manono and BoNz1 my result a quite fantastic. I have learned a lot here!

I have started using knot for my rip 2 weeks ago. The more i use it the more i like it... But nothing beat VDub for extra setting and finishing the job!

Thanks a lot guys!
