Jerky, Jittery DVD

[leng]

Hello All,

I just authored my first dvd. I am putting my old 8mm tapes to dvd. I capture the video from my Sony Handycam through a Hauppauge PVR-150, and it is saved to my hdd as an .mpg file.

I use Nero Vision 4 to create the dvd. The finished dvd is unwatchable on my (few year old) home dvd player. It is jerky and jittery. It seems to play fine on my computer in either Nero ShowTime or Windows Media Player.

I have tried burning straight to disc and also to hard drive and then to disc, with the same result. I am using Taiyo Yuden media, burning at 4x.

Any help would be appreciated.

Thanks.

My specs are:
AMD Athlon64 x2 Dual Core 5000+
2GB Ram
250GB WD HDD
TSST TS-H653A 16x DVD +/- RW
Windows Vista Home Premium.

From your description I would say the problem is probably field order reversal. You card has most likely captured top field first, but somewhere alone the way the field order has been reversed to bottom field first during encoding. Deinterlacing in the software players has reduced the effect on your PC. I suspect if you play back one of the VOBs in virtualdubmpeg2 you will see the same problem.

I don't know of a nice way to fix it without reauthoring. If you demux the mpeg out of the VOBs you can use Restream to fix the field order, but the you have to recreate the VOBs and put them back. Probably easier to just create a new menu and author a fresh with the fixed mpeg files.

Thank you for your reply guns1inger.

I certainly don't mind reauthoring. I want to get this right before jumping in to converting all my 8mm's to dvd. I'm not sure what you mean by:

"Probably easier to just create a new menu and author a fresh with the fixed mpeg files."

How am I fixing the mpeg files? I do notice in Nero Vision 4 that I can set the
*Sample Format* to:

Automatic (which is what it is set to now) or
Progressive or
Interlaced (top field first) or
Interlaced (bottom field first)

Do you suggest using something other than Automatic?

Really appreciate your help.

Try this trial version

http://www.videohelp.com/tools/TMPGEnc_DVD_Author

The latest version can author as DVD or .divx and can convert to either format.

If your files are DVD compliant they should just go in and be unchanged. The other handy feature is the preview function so you can see what it will look like on the DVD player.

[guns1inger]

Honestly, I wouldn't use NeroVision at all, but that's just my preference. If you are going to go through the re-encoding, then try setting it for Interlaced, Top Field First. Just do a sample and test to be sure.

It seems to play fine on my computer in either Nero ShowTime or Windows Media Player.

Missing media info ? , was it + or - used .

Home dvd players wont just play anything , but a pc generally will without problems .

Confirm the media used is actually supported by the home dvd player first .

Practice the compatability rules : Dvd-r only , no more than 4.3gig per disc , 4x burn (or half the medias max burn rate)

Then work on the issues from that point .

I suggest imgburn to burn under vista , instead of nerovision (issues) .

[leng]

The media used was both. I tried it on a + and -. I am going to try the suggestions. I really appreciate all the help. Thank you.

A quick followup question. I see that my Hauppauge PVR-150 outputs the files as dvd compliant mpeg2's. I also notice that Nero Vision 4 re-encodes the files, which seems to be where my problems are. Is there a authoring program (preferably free) that will just take these mpeg2's and allow me to create basic chapters. Then I can burn using my Nero Burning Rom program and hopefully not have the jittering effect?

Thanks in advance.

Skip Nero altogether.

Author with TDA or SVCD2DVD, both inexpensive but good.
ImgBurn burns better than Nero, and it's free too.

I have 10 DVDs to burn and I had this problem on the second one. I was suspecting the player was the problem.
Tried DVD+RW and a DVD-R discs, same problems.
The strange thing is that I captured all the material using my Hauppauge PVR500. Cut with Cuttermaran. Encoded with TMPG and authored with DVD-lab.
I did exactly the same thing for all DVDs.
I didn't burn the others to see if they will playback ok or not.
Will try to open the files on VirtualdubMPEG2 to check.
I really don't want to re-author all the discs :/
I'll look for a thread I read someday on how to demultiplex all the DVD to change the audio files and multiplex it again. Maybe it works for the fixed mpg too.

[Caple]

Well, ReStream says my file is "top field first", so it's ok.
I'm capturing analog cable with a Hauppauge PVR 500.
So I believe I don't have any option but try to reencode all the files (10 DVDs) and reauthor again (or just change the vob files like I read on a guide here).
Any other way?

[Caple]

Just another question.
The latest DVDs I burnt took me about 45min, instead of 8~9min when burning at 8x. Of course I knew something was wrong.
Got a burner from a friend to do some tests and his burner is working fine. Also my computer boots faster then before (see http://forum.videohelp.com/topic330647.html).
So, my burner is defective. It burns, but really slow. Can it be the reason for the jittery playback, considering the jitter is only on the TV, not on the computer?

[guns1inger]

Separate problem. Sudden reversion to what is basically 1x speed usually means your drive has dropped back to PIO mode. Right-click on My Computer and select Maage. Click on Device Manager, then open up the IDE controller branch. Double click on the primary IDE channel, then click on Advanced Settings. Check the current transfer mode on both devices. If there is a device attached it should say DMA. Repeat for the secondary IDE channel. If either channel shows a device in PIO mode, uninstall the channel, and restart windows. Your burning should return to normal speed

[Caple]

That's not the problem. It is DMA. I checked before posting here :/
But, as it's slow as hell, I thought it could be the reason for the jittery playback.

[Caple]

That's funny.
I never used a jumper on my DVD burner.
Now I jumpered as master and Windows is booting faster (like with my friend's burner) and is burning normally again.

[Caple]

Sorry to bring the topic up again, but I need some input here.
I'm still trying to make it play fine.
The jittery problem is not the discs, cause I tried three different brands.
It's not Nero too. Cause I used other software and the jittery still there.
It's not my DVD recorder. Cause I burnt other stuff after that and everything worked ok.
I extracted the mpg files from the DVDs using VOB2MPG and burnt using ImageBurn, playback is still jittery on my DVD player.
The DVD player is not the problem too, cause it's jittery on my cousin's player too.
So, the problem was the encoding on TMPG or the authoring on DVDlab, right?
Restream says the files are top field first, so that's not the problem.
What should I do?
Reencode the DVDs with DVD Shrink, choosing 99% quality, just to make it reencode again?
I don't know what to do.
It sucks to only have the computer as an option when I want to watch those videos.
Any, any help is much appreciated.
Thanx.

Use ReStream to change the field order to BFF and test play. Otherwise post a few seconds so we can see it happening.

[manono]

Restream says the files are top field first, so that's not the problem.

It is if it's supposed to be BFF.

[Caple]

Damn, tested it as BFF and it plays fine!
I was 100% sure it should be TFF.
I read, years and years ago, don't remember where, that analog source was TFF and digital source was BFF. I'm sure I read that. So I had it on my mind. Didn't even try to change to BFF on ReStream because of that.
Seems like after all this years capturing and authoring I'm still a real NOOB!
Thanx!
