DVD2AVI_1.77.3 - CAN'T GET PERFECT AVIS OUT OF VIDEO VOB FILES

Cunhambebe wrote on 4/15/2004, 3:08 PM

I'm planning to rip a dvd vob file and then convert it to avi for editing purposes (totaly legal ones) with Vegas. I've tried a couple of times with a prog called DVD2AVI but the result with video files (movie/film, seems perfect) present some kicks when you have fast camera movements from left to right and vice-versa and/or when there's fast action on the screen. I was just wonderign if I can do this with Gordian Knot, too. Can anyone help me with that? Is there a perfect config for DVD2AVI in order to fix those "kicks"?
Thanks in advance

I did email you a response but as I didn't get a reply I assumed you'd gone to sleep or found the problem.

What I still don't know is is this effect constatnt over several frames. If it looks OK in the AVI but not in the mpeg then what bitrate are you encoding at?

Sorry, I went to sleep yesterday - I was very tired.
Well, the compression options in Vegas are: MPEG2; DVDA NTSC video stream; best, VBA 8000 (all the best options). Same in TMPGENC. Have you already received my e-mail?

I don't understand why there are these bands on final mpeg video. AVIs generated from VOB files seem so perfect but as soon as you render them as MPEG, that's the resul: banding. Maybe there's a config option with DVD2AVI that I don;t konw, even some related to de-interlaced video...I don't know, I'm very confused since so many people keep sending guides that simply des not work (despite the fact I thank them all for trying).

How's the weather in Australia tonight? Here 11:42 am.
Thanks!

My original advice was to NOT have DVD2AVI do anything to the video, but instead to put the VOB directly on the Vegas timeline, and have Vegas render a DV AVI file. You then start a new project and put this AVI file on the timeline. Your subsequent posts confuse me, because you keep talking about the video created by DVD2AVI. If you create video with DVD2AVI, then you must have the Colorspace and YUV->RGB settings set correctly. In addition, you must choose a video codec when encoding that is capable of high quality.

I still recommend not using DVD2AVI to do anything with the video.

Thank you Johnmeyer. sorry for this is so confusing to you. Can you imagine how confusing it is to me?
You know John, I don't understand. If there's no way to get good results with DVD2AVI, why using it?????? One more thing: I've tried to open the avi (created this way VOB>DVD2AVI>VFAPI>VEGAS= AVI) with TMPGENC to re-render it as m2v, following your guide on inverse telecine. It worked, but as soon as I edit this MPEG file and give it a final re-render, the banding is back.
Some other users at DVDRhelp have told me about selecting TV scale in DVD2AVI. Let's see if I can do it. I'll reply as soon as I get the new results here.
Thanks again for the valuable help.

Thank you johnmeyer but putting VOB file directly on Vegas' timeline does not work at all: the result is garbage. Thanks again for the trial. Now, you left me thinking about what you wrote down:
"If you create video with DVD2AVI, then you must have the Colorspace and YUV->RGB settings set correctly. In addition, you must choose a video codec when encoding that is capable of high quality."
By any chance, do you know how to set colorspace and YUV->RGB correctly? Nothing have worked until now. I almost finished my project. Just have to fix this. Thanks again for you help. :)

I guess I know what the problem may be: the AVI is 23,976 IVTC Film and the properties for my project to render the MPEG file are NTSC DV 29,970. How can i convert this 23,976 to 29,970? Any hints? Virtualdub?
Thanks.

I don't know how to fix this problem. Please, I do need some more help.
Thanks in advance

You can't "convert" frame rates, but you can render to the new frame rate in Vegas with no trouble at all. Vegas will take care of it for you automatically. If you are getting fuzzy or "doubled" images then you can disable resampling, which will duplicate occasional frames rather than blending them together. This will produce a sharper image, but it may be a little jerky.

In either case, this has nothing to do with the banding problem.
