Help! The blurred resulting image in DVD ripping!

[Ewen Howe]

I researched around this site and failed to find a answer of my problem.

I am very newie in DVD ripping and I have tried to ripe DVD into VCD or SVCD. I followed the Sefys AIO newbie DVD Ripping Guide and made a few trials. The sound, picture colour etc look fine. But, all resulting mpeg1 or mpeg2 movies are showing the blurred image at motion objects/scene, though still object/scene looks fine. I used Smart Ripper to copy, DVD2AVI for frame serving (the version I used is a little different from Sefys Guide) and TMPGEnc for encoding. All of the tool are the latest versions. Can anyone tell me which section may cause this problem, copying? frame serving? or encoding? How do I overcome this problem. Thanks!

The blurring and motion problems you see are most likely the of low bitrate. Try enodeing in TMpeg using 2-passVBR. It takes about twice as long to encode but I find it very effective at getting rid of the problems your seeing.

I encoded a test with TMPGEnc Plus using 2-passVBR as you suggested, but the result show little improvement and the video quality become even worse than that using CBR...

hi there,

here's couple of things you can do..

1) 2 pass VBR, like wulf109 said (or at least any VBR is better than CBR)
2) motion search accuracy set to high quality (slow)
3) this is a more complicated one

when you're making your .d2v project file in dvd2avi, an "info" box should appear. in that info box, you should see a video type. it will either be FILM, NTSC, or some percentage of either. if the video type of the movie is 90% FILM or greater, you should turn on forced film and encode in tmpgenc as 23.976 fps + 3:2 pulldown.

if the above still doesn't help, you should try these

4) up the bitrate to 2000+ kbit/s
5) under field order (in tmpgenc's advanced menu), just reversing the field order setting and see if the problem goes away

Ok, I will try those suggestions one by one to see which one will work for me.

BTW, I have a little question for the DVD2AVI that I am using, which is a little different from what is described in Sefy's Guide: Under Video>Field Operation>Forced Film, here there is no further choice as for 23.97 or 24.00 as the Guide. Under Audio> there is not MP3Compress. Am I using a wrong version or what? Also, the DVD2AVI is the same software as that inside the DVD2SVCD all-in-one? Thanks!

I will post my trial results as soon as I finish.

hmmmm.....

no, no....you need to do 1, 2, 3, and 4 at once....

you will notice significant improvement if u do them together...

Thanks for reminding, I've got it!

Now, I come back with the result of trials following the suggestions of poopyhead. Although the motion blur is obviously reduced, unfortunately, the results were poor, unsharped, darker, definitely worse than the results done with Sefys Guide except the motion blur. Audio was fine.

Let me follow poopyhead's list (it seems to me that the problem is only relating to TMPGEnc settings) to see if I did anything wrong:

(1) At the Video menu, set 2-pass VBR;
(2) At the Video menu, Motion search precision set to high quality (slow). This causees a longer encoding time;
(3) At the Statistical Window of DVD2AVI ('info' box?), the video type shows FILM 92% (actually the percentage is varying, at beginning of movie it shows 73% and soon become 91-93% and stay around there). Accordingly, at the Advanced menu, I ticked the boxes of 'Inverse telecine 24fps and Inverse 3:2pulldown (rather than Source);
(4) At the Video menu, the bitrate shows 2520 kbits/s, so I left it as it is.
(5) At the Advanced menu, the field order set to the other than Bottom filed first (field B) (there are only two there).

Those are what I did. I am still puzzled with my previous question about my DVD2AVI which lacks the Forced Film allowing me to force 23.976fps than 29.97pfs. But, when I preview the .d2v file with DVD2AVI, the movie shows satisfactory without noticable motion blur. But, after encoding....I am going to try some other settings myself and continu to appreciate further advice and suggestions. Thanks!

well, you need to get another version of dvd2avi that will allow you to force film (this is critical to better results). once you do that, you will not need to use inverse telecine in tmpgenc. also, in tmpgenc for 3:2 pulldown, the 3:2 pulldown option i want u to check is in the VIDEO section, NOT the advanced section.

Thanks a lot, poopyhead and walf109, for your pateince and detailed guidance! I would like you all know that, the motion blur problem has been overcome. The problem was due to the DVD2AVI I used, the version is not capable of Force FILM to 23.976fps. I tried to install a few versions and found eventually the ver.1.86 is the right one. I made the frame serving with it and encoded with TMPGEnc Plus. The resulting VCD or SVCD show no obvious motion blur. I also tested the various settings including those suggested by you but the results show no obvious difference from those in the Sefys Guide....

However, the Aspect Ratio becomes problematic. My original movie is in 16:9, but the .d2v file showed up in TMPGEnc as 4:3 which is hiden under Settings>Video, making it unchangable there. If I encoded into VCD(MPEG1), I set the Aspect Ratio as 16:9 under Setting>Advanced and resulting in a 16:9 movie. If I encoded into SVCD (MPEG2), evenif I set it as 16:9 there, the resulting in movie became 4:3 automatically. I tried a few settings around there but failed to figure out. Could you ofer more help? Thanks again!

you're suppose to adjust the source aspect ratio in tmpgenc to what dvd2avi tells you.

so, in dvd2avi when you're making the .d2v project file, the "info" box that appears will tell you the source aspect ratio (either 4:3 or 16:9). this is what you enter in tmpgenc as source apsect ratio under the advanced menu. depending on your source, the dvd can either be NTSC or PAL...for me it's NTSC, so i would choose 4:3 525 line NTSC or 16:9 525 line NTSC, depending on what dvd2avi indicates.

under that same advanced menu, you should set image positioning to either full screen (preserve aspect ratio) or fit to frame (preserve aspect ratio) depending on which verison of tmpgenc u have

under the video menu, you should set output to be 4:3 Display NTSC. if you're gonna watch it on a widescreen HDTV (then the output would be 16:9) otherwise, regular TVs are 4:3. again, NTSC or PAL depending on which region you're in.
