Choppy playback within UVS

[esclava]

Hello!

I¡¦ve searched the forum and from what I¡¦ve seen my problem hasn¡¦t been mentioned¡K

I¡¦m running UVS11.5-Plus
I¡¦m trying to import my .vob files VIDEO_TS folder: Capture => Import from DVD/DVD-VR/AVCHD => Import DVD Folder

When the capture process finishes, almost everything is normal, that is, I can edit my movie and even play it. However, there are certain scenes that even as a .UVS project file are choppy or jerky when I play it in the preview window (I guess that¡¦s what the main view window is called?). This has never happened to me before. The finished project has been jerky due to a bad burn/render, but never has it been choppy from the project view window unless I had applied filters, which is not the case.

When I select the clip in the timeline and then play it, it plays just fine ¡V no choppiness at all. And if I had applied a filter, I know that selecting the clip in the timeline would bypass any changes I made. (If I¡¦m not mistaken, selecting the clip in the timeline and playing it in the library work the same because you¡¦re actually playing the original file¡Kit¡¦s just a shortcut.)

Here¡¦s what I¡¦ve tried so far:

1. Tried the entire process with the new VS12 ¡V same choppy result
2. Saved the file ¡§same as first video clip¡¨ ¡V same choppy result
3. Saved it without SmartRender ¡V same choppy result
4. Opened a totally new project file and went to File => Preferences =>Show message when inserting first video clip in the Timeline and selected the option to keep my project properties the same as my original clip ¡V same choppy result
5. Re-imported my .VOB files fresh (the same .VOB's on a backup DVD) ¡V same choppy result
6. Chose Share => Create Disc => DVD => No menu => Save as Disc Image and let that process complete ¡V same choppy result
7. Imported a different set of .VOB files for a totally different project and it plays perfectly in the timeline and the rendered project is perfect.

So now I¡¦m thinking this all points to a corruption on my original discs, since all other projects are working fine and this is the only one that is this way.

Does anyone have any suggestions that I haven¡¦t listed above? Has anyone else experience this weird problem? If so, how is it solvable?

I'd really appreciate any help you can offer!

¡V Thanks ¡V

First, can you please look at your DVD (that you are trying to import from) in Windows Explorer and confirm that it has a structure of files that do include .vob files. I know it sounds a bit like teaching granny to s*ck eggs, but what I am trying to exclude is that somehow or other you have a hybrid video i.e. a video DVD but one which uses high definition AVCHD video on it...

Next, have you tried simply copying the contents of the DVD to a folder on your computer and importing from there, or at least changing the extension of the .vob files to.mpg. Then opening one of the .mpg files in VS. If you can do that, please right click on that mpg file inside VS and copy all its properties here, please. Mind you, from all the various things you have tried (and especially your step 2, I would think that excludes getting the field order somehow or other mixed up)...

Indeed, does the mpg opened that way display the same problem?

But once these things are all excluded, I am afraid it *does* sound as though your DVD is corrupt in some fashion...

Okay, I double checked my original DVD and yes, the files are all in .vob format.

I have been trying to import the .vob files from a folder already on my hard drive. So it won't work (I mean, it's choppy) directly from DVD or from a DVD Folder.

I changed the file extension from .vob to .mpg, dragged it into my VS library, and I get the same choppy results.

After I dragged the newly extension changed .mpg file into the library, here are the properties of that clip:

FILE
File format: NTSC DVD
File size: 1,048,242 KB
Duration: 1605.572 seconds

VIDEO
Video type: MPEG-2 Video, Upper Field First
Total frames: 48,119 frame(s)
Attributes: 24 bits, 720 x 480, 4:3
Frame rate: 29.970 frames/sec
Data rate: Variable bit rate (Max. 9200 kbps)

AUDIO
Audio type: Dolby Digital Audio
Total samples: 77,067,467 Samples
Attributes: 48000 Hz
Layer: None
Bit rate: 192 kbps

I forgot to mention in my first post that another step I tried was to change the field order from Upper Field First to Lower Field First, and then to Frame-Based... I honestly don't know what all the field order info means, but changing the field order didn't correct the problem either.

Thanks for your suggestions...

Hi again! On this same topic....

This time I am struggling with one of my family movies that I have actually edited in VideoStudio. When I originally brought my footage into VS, I had added titles to some of the scenes and added a few things in the overlay tracks. I burned out the movie to an .iso (back in 2009) and now I noticed there is something I want to change in the movie. SO I re-imported it into VS and I noticed now that in all the places where I had originally placed titles in my overlay track, the video footage gets unbearably choppy, like I am missing 100's of frames per sec. It's really horrid. However, when I play that imported movie file outside of VideoStudio, it plays normally. So I tried ignoring the problem of choppy jitters within VS and I saved out my "new" changes to another DVD Folder ISO. (I did that because sometimes there is normal jitter during playback in VS that goes away after a burn.) But no matter what I try, the footage surrounding my titles in overlay jumps like crazy. Does anyone else have that problem?? This is really aggravating! I know there has to be some solution. Thanks for any help!
