AVI Capture OK DVD Terrible

Post by Jabone »

Ok, I've been working with this since Christmas and at the time I gave up because it was a gift and sent it out as-is. But now I simply want to capure about 15 minutes of VHS info and burn a CD.

The resulting AVI is nice and plump. My capture settings match my project settings for AVI. When viewed in media player all looks well. Final cap size is ~ 4 gig.

Then I add menu and burn to DVD. Burn size is a measly 600 meg, even with burn options set to max quality. Everything burns OK but when played back on NTSC DVD player video is full of horrid jaggies... no aliasing.

What am I missing?

Hi Jabone,

Your missing something..:)

Are you rendering your video project to NTSC-VCD or SVCD, and then burning a DVD, using NTSC-DVD? The reason for the question is you say you want to burn a CD, then you talk about playing it on a DVD player? While I know that DVD players are capable of viewing SVCD and VCDs, it seems that you used the wrong settings.

VCD or SVCD will give you good quality, but it will be nowhere near what a DVD would be, given you are capturing to DV-AVI.

In order to provide more accurate advice, we need to know a lot more information.

1. Project Properties
2. Workflow, excactly what steps you performed from capture to burn.
3. Settings you used in rendering your video file, if you did.
4. Settings used to burn a disc.

You can also follow Steve's tutorial From Camcorder to DVD..

You surely missed this http://phpbb.ulead.com.tw/EN/viewtopic.php?t=8959

and did you look at this http://phpbb.ulead.com.tw/EN/viewtopic.php?t=27?

How could we possibly guess what exactly it was that you so obviously did wrong?

More detail please.

Read all of that...

And followed the tutorial to a T, 4 times on this project alone

The only erroneous comment was that I was burning a CD, mis-spoke, burning a DVD.

I went through this entire exercise, like I said, around Christmas... politely posted all the info needed. After doing so, the "experts" were stumped (I assume) by their lack of responses.

So never, mind don't feel like going through the hassle and tolerating snarky comments.

Sorry, Ja, that we collectively got your hackles up. But it is a big ask to think we might remember details going back to last Christmas.

And I know you say you followed the recommended procedures to a T, but above you say you captured an AVI (DV/AVI?) 4GB in size, but when you burned it, it was only 600 MB. This implies to me that in fact you did NOT follow the recommended procedures to a T. And I am NOT trying to be snarky here. The comparative sizes of these two results also sounds about right, by the way.

In fact, though, what you say implies to me that after capturing (and editing?) your video, you jumped the all-important middle step of going from your (edited?) AVI direct to burning it to disc. Instead, I think you should have been first going to Share > Create Video File > DVD, and producing a DVD-compatible mpeg-2 file. Since the AVI was captured from VHS, I am assuming again that you would set the Field Order to Upper Field First/Field Order B since that is what is the usual setting for original analogue capture. Getting the field order wrong is consistent with the jaggies you mention. And consistent with your comment about the highest quality burning settings, you would have set it at a bitrate of (again) 7 or 8000 kbps (though 6000 kbps is probably more than enough for analogue source material).

But instead of this last step, it sounds to me like you opened the burning stage immediately after any editing (Share > Create Disc), with your AVI still in the timeline. And you used either the AVI file or even the project VSP file in the burning module, and burned. Asking a computer to burn a DV/AVI file direct to disc (which means it is converting it to mpeg-2 and then doing the multiplexing and burning, all on the fly) is a big ask of a computer, especially if it is not heavily endowed with resources. I see from your computer specs that you are far from under-resourced. But the fact remains that a lot of people have trouble if they jump the intermediate step.

If I am wrong in ANY of this, then please tell me where. Hell, I don't even know which version of VS you are using.

In fact, mentioning file sizes, the other thing which might be causing a problem, depending on the version you are using, is that you are only trying to burn a small file, of 600 MB in reduced size to a DVD, which can take about 7 times the size of the file you are trying to burn. In older versions of VS, I recall they could not burn anything less than 1 GB with any hope of success, and actually padded out the file to make sure it was above 1 GB. But I really don't know what the most recent versions do in this regard as I have never tried to burn a small file to a DVD.

Anyway, without any snarkiness intended, these are just some of the reasons why we need more information on exactly what you have done and which exact properties are involved. Hope you can help us help you.

Resolved... I think.

Post by Jabone »

Ken, thanks. I never meant to suggest someone should remember my issue from seven months ago.

My hope was someone would pipe up and say "fixed in 10.."

Sadly, that is not the case. Well, maybe all these silly bugs are, but I'm not going to spend the upgrade money to find out this software is just as finiky.

All my project properties matched the capture settings of the AVI and I did create the MPEG prior to building the DVD menus, etc..
I varied resolution from 720 down to 320 w/out any luck. I literally did everything in the tutorial multiple times. It's printed out and taped on my wall.

I tried creating an ISO and DVD files, nothing seemed to matter. Out of pure frustration I burned the same files with Nero, and guess what.. perfect DVD. I'm not sure if VS9 has an issue with my burner (NEC ND-3550A), a +- burner. Since this I've read that others have issues ripping or burning audio disks with some software. Don't know. I will be buying a new burner tomorrow for a test.

The only issue (outside the finiky nature of the software) is that I cannot capture an AVI longer than ten minutes. After that, the size explodes (17gig for 10 minutes) the video is 1/4 speed but the audio is correct speed. If I break it up into smaller caps, no problem. The UI says it's not dropping frames. Perfmon show no lagging disk or memory writes... But that is another issue other than the one I originally started.

What capture device are you using? I got a little confused in my original post since you said that 15 minute AVI was around 4 GB, and that would be about right for a DV capture. That in turn would imply you have a capture device which can capture DV digital format which takes up about 13 GB per hour of video. However, your latest post suggests that in fact you are capturing uncompressed AVI, which runs out at around 65 GB per hour... But that would still not explain what is going wrong. As I said in my other post, the jaggies you mention sound as though it could have been a field order problem, but now you say you have successfully burned with Nero. So, like you, I am stumped! :cry: :oops:

Device

Post by Jabone »

Ok, to be clear, the jaggies are not as bad... close enough to the point of where I can understand the image on the screen.. before it was terrible.

More "smoothing" via compression look.. if that makes sense?

The device is my NVidia 7800 GPU. The mfg, BFG, bundled Ulead SE 9 with the card and I subsequently purchased 9. In my quest for lower blood pressure I've tried various driver updates and roll backs.

To be honest, it seems to have an issue with the audio portion. The source is a VHS-C camera, in Mono. If I set the audio portion of the capture to anything other than stereo it all falls apart. Falling apart being what I mentioned about the video running super slow and file size exploding. One would think less audio (mono) would be less intensive. But again, that's an aside issue.

I was setting it to mono, because, well... that is the source. The video properties and burn process have always been the same. The resolution I have changed (trying to sort this out), but the field order has always been "upper.." in cap and project properties. The frustration is enough to send me out for a DV cam. :D
