Problems Editing Ripped DVD Content

This is and is not something related to VRD. I ripped a DVD. I wanted some of the video footage for a project I am working on.

I used Riptit4me. It went flawlessly. I found the vob container the video I wanted. I used VOB2MPG to convert to an mpg. All this went without incident.

I played both the vob and the mpg in VRD and they played fine. The only issue was an abnormally long loading time before I was able to play them.

Thinking all was fine I went to my editing software; Ulead MSP and Sony Vegas Studio. When working with the mpg there it has hiccups in the video.

I thought I might have done something wrong during ripping so I did it all over again and got the same result.

The abnorally long loading time in VRD strikes me that it is having a time negotiating the file, but manages. Maybe it is far more forgiving than my other software?

Am I doing something wrong? Do I need to run the footage through some sort of mpg cleanup tool?

If it was a commercial DVD, theoretically it should be fine.
Maybe your ripping software leaves something to be desired.
Try using the QSF feature - run it through, then save to a file.
Now, reload -that- file into VRD and see how it works.

Hi Anole,

yes, it is commercial DVD . I already tried the QSF feature, but it did not help. Both the original and the QSF files played fine in VRD. VRD seems far more tolerant than my editor programs.

The ripping software has some sort of feature called fix vts. I will try that.
I will let you know.

Thanks!

OK, I tried the Fix VTS, but the picture still momentarily stutters every once in a while. It is like the picture pauses, backs up a frame and then continues on.

Is there some sort of other ripping software I could try?

RipIt4Me is the best ripper there is--you need to be using the latest version 1.6.4 I think.

But why use VOB2MPG? Instead use phd's DVDCopy utility that you will find here on this site, and apply it to the VIDEO_TS you have made. DVDCopy will QSF+Copy the VOBs to a single mpg file that you can edit in VRD.

It oughta work; this should give you perfect mpg to use in your Ulead/Sony programs. What it WON'T do is protect you from the FBI agents that may show-up at your front door! ;)

MSP and Vegas may be hiccuping on the 3:2 pulldown material also.

Load the file into VRD and check the thumbnail timeline. navigate the file a little. Do you see "P" frames listed? If so this may be your issue.

I can't speak about Vegas but which version of MSP are you using? Have you applied any patches or updates to MSP?

I am running MSP 7.30. I just checked and I am running the lastest patches which included 3:2 pulldown.

I ran VRD and brought up the time line. I see no "P" anywhere on the timeline. I zoomed out to 0.5 seconds/frame and still see nothing. Where should they be?

In the mean time I am going to try the file I produced with DVDCopy.

Thanks for all the help.

No Cigar!

Even the file created with DVDCopy does the same thing. I am not sure, but it even seems to always be in the same spots on the movie. It looks as iff the frames in that area are momentarily played out of order. It may play a frame many frames ahead then back where it should be, then another place.

I am not saying totally out of order. Let's say a series of 10 frames starts to play. It looks like it might something like 1,2,5,3,4,5,9,... Jumps ahead momentarily, then back. Really strange.

Since many of you have done this and have never had a problem I am sure it has to be me.

One thing no one has commented on that still intrigues me. This file is a hair over 1GB. Load time in VRD before it can play is probably 5-10 times as long as a file of 5GB of DTivo extracted video.

Is this normal?

Is the load time long before or after you QSF the file?

To see if the file has "P" frames, move to various points along the timeline. It will look like this in the thumbnail area of VideoReDo.

What are the properties of the file in VideoReDo? Ctrl+L

In MSP, are you seeing the hiccups playing the file after renderin in MSP? In preview viewer? In source Viewer? Are you enlarging the screens in MSP or using the defaults?

What are your project settings in MSP?

I double checked VRD for "P" frames. None are present.

What are your project settings in MSP?
The source window plays fine. I have the preview windows set for high quality playback. The file hiccups in the preview window after rendering . The windows are very close default size. The hiccups do seem to happen in the same place each time. I tried to "make a movie" by setting the preview area at the hiccup and clicking the "make a movie" button. It got to about 95% and locked up.

Here is a screen print on the project settings.


Does this help?

OK. The MSP settings look like the default MPEG2 settings.

2 things I can suggest:
1. Save the file in VRD with MPEG audio and import into MSP

2. Upload a 30-50 segment of the file to the FTP and I can try it on my version of MSP to see if it is reproduceable.

Confirm that the segment has the same problem in MSP before uploading.
ftp://upload:upload@videoredo.net/

Create a folder with a unique name and place the file in it.

Let me know when it has been successfully uploaded.

I have uploaded the folder as requested.

Interestingly, the file I created for you with VRD with mpeg audio does not exibit the jerky/choppy playback the original file did. The only problem is that in MSP it shows a compression rate of 64% (I think) when it started out as 0%. I can visibly see the difference.

I also created file with MSP that still exibits the problem.

I have uploaded both in the folder "SMaye ripping problems".

Both of the files have MPEG audio. Neither have AC3 audio.

Do you have a segment of the original file?

One is labeled "VTS_05_1 B4 VRD.VLST.mpg" but it looks like it was already processed since it has MPEG audio.

Folder name changed to: "SMaye ripping problems t3637"

Hi phd,

You are correct. I can't believe I missed that! I took the vob from the DVD and processed it with DVD Copy to produce VTS_05_1 VLST.mpg.

This file still had the hiccups. The file

VTS_05_1 B4 VRD.VLST.mpg

is simply a clip from this file.

I took a similar clip from the same file and ran it thru VRD as requested. I made sure to select mpeg audio at "save as". The file created was VTS_05_1 mpeg audio.VLST.mpg. This file was cured of the hiccups.

I am currently traveling and have no access to my home PC. I will work with my wife and see if I can upload what is needed.


I will be back in touch when I get the proper file(s) uploaded.

Thanks for your help!

Hi phd,

I got back and arranged the file as you asked. Sorry for the lengthy names. I just wanted you to be sure which one you had. I checked the file and it definitely exhibits the hiccup. I have uploaded it as "VTS_05 from original vob 1-19-2006.mpg".

One thing I am having a problem understanding is no matter what I do I can not seem to avoid compressing the file. I mentioned this above in a previous reply.

When going through VRD I went from 0% compression to 65% compression. As I was creating the clip in MSP I just uploaded I set compression to highest quality and checked smartrender. The result was a file with 42% compression.

Maybe I am wrongly associating degrading PQ with compression, but I do see a significant difference between the original at 0% and the others at 42% and 65% compression. Is there no way to avoid this?

I looked at the file "VTS_05 from original vob 1-19-2006.mpg".

What preprocessing has occurred with this clip to create it?

It appears to be somewhat out of sequence.

Perhaps your method of extraction needs to be refined a bit.

  1. Ripped the original DVD using Ripit4me
  2. Took vob containing this video and converted to an mpg file using "vob2mpg" (but also got the same "hiccup" results using DVD Copy).
  3. Loaded the mpg created by vob2mpg in to MSP where I edited to create the mpg segment you looked at. During this stage I could clearly see the out of sequence frames BEFORE the edited mpg clip was created, so I don't think the problem occurs during this process

So far, the one thing that eliminated the hiccups was when I saved the mpg in VRD. The only bad thing is the compression and loss of PQ that resulted.



BTW- When I try to load this vob (1GB) as ripped from the original DVD it takes 55 seconds for VRD to load. When I take the mpg created from DVD Copy it takes 5 seconds. Which is more normal. That's what I meant by the long load times.

You might want to try an alternative extraction method. It looks like frames are out of sequence.

It should not be necessary to use vob2mpg. VideoReDo can QuickStream Fix a VOB.
