Convert Step Problems

[jfox]

Hello, my name is J.Foles and I have some problems when I make my DVD with Ulead VideoStudio 10 plus.
The source of DVD is a AVI film with the follows properties:

MPEG files
24 bits, 720 x 576, 25 fps
Frame-based
(DVD-PAL), 4:3
Video data rate: Variable (Max. 7000 kbps)
Audio data rate: 224 kbps
Dolby Digital Audio, 48 KHz, 2/0

I want to make the DVD with these properties

MPEG files
24 bits, 720 x 576, 25 fps
Frame-based
(DVD-PAL), 4:3
Video data rate: Variable (Max. 7000 kbps)
Audio data rate: 448 kbps
Dolby Digital Audio, 48 KHz, 3/2(L,C,R,SL,SR)

The program always gives me an error that he have convert Step problemes.

Its possible to meke what I want, transform 2.0 im 5.1 using VideoStudio10, or its better make the new DVD with the original properties.

Sorry about my inglish, it's now the best but I try to do my best.

Best Regards

J. Foles

Hi J.Foles, and welcome to the forums..

You stated that your source clips were AVI but yet your specs show MPEG. This tells me that they are possibly DivX, or Xvid, or MPEG-4? Where did you get the AVI film? Download from the internet, or off a DVD?

AVI is just a wrapper or container for various formats. VS has problems with some of these highly compressed formats. A second clue to this is the Frame-based field order. Most DV (AVI) captured from a camcorder uses Lower Field First, while analogue (typically from a VCR) use Upper Field First. Frame-based is generally used for video that is going to be viewed on a computer.

When the "Convert step has got some problems" error shows up, it tends to have something to do with the video files, that VS needs to encode. Your MPEG files may be corrupt, or have been corrupted during the process.

Hi, vidoman, thanks for your explication.

I tell something wrong. My video files have the extention MPEG and I tell that they are AVI. Wrong Information.

This files are captured from VHS with Pinnacle Dazzle DVC 90. I order to Dazzle to create MPEG-2 format and audio dolby digital 2.0.

I try to comvert some files in VS and the problem persists. VS refuse to convert to mpeg and 5.1.

If I make my DVD's with MPEG-2 format and audio dolby digital 2.0 everything Ok.

With these properties it's possible convert in audio 5.1 ?

Maybe the good choice is make DVD whit the original properties unless I capture all my films.

Do you have any jerkiness, stuttering ? If so that is indicative of having captured to the wrong Field order. Unless the Dazzle is capable of hardware transcoding, analogue to digital, you should capture it to Upper Field First.

That may not be your problem, but thought I'd mention it just in case there may be some other symptoms not convered yet.

I just ran a quick test using VS10+, where I used an MPEG-2 that had AC3 Dolby (2.0), and created a video file where the only change was to the audio, which I choose Dolby 5.1. VS rendered the file no problems, the audio to 5.1.

So I suspect a problem with the MPEG files. Are you capturing the video to MPEG-2 or MPEG-1?. If you capture to MPEG-1, then when trying to convert them to DVD compliant MPEG-2 Dolby 5.1, VS maybe choking on that. MPEG-1 is not a DVD compliant format.

Next are you following the recommended procedures, found in the top sticky of this forum? or Are you capturing your video clips, editing them, then without creating a video file from your edits (Share>Create Video File) are you going straight to Share>Create Disk with a project in the timeline?

After all that above I re-read your original post. I think your problem is that you are capturing to Frame Based.. You should be capturing to Upper Field First if you are wanting to create DVDs. I really don't know why VS would be choking on that, but I do know that the Field order should be UFF for analogue video.

Another possibility is the audio data rate of the 5.1 output, namely 448 kbps. Some people have problems with 2 channel stereo Dolby when they use the 'wrong' (too high or low) audio rate. In my version of VS10, for 5.1 Dolby the default seems to be 384 kbps and that seems to work fine the couple of times I have actually burned with 5.1 audio. So Ron, I am wondering if you used 384 or 448 in your successful test.

I was also initially struck by the Frame Based property. However I did not say anything at the time because I suspect it might be a product of the capture device. You may recall, Ron, a few months ago there was a short debate about certain capture devices which do not clearly indicate whether they capture Upper or Lower Field First. They are instead described as using 'progressive scan'. Now it seems to me -- and I could be completely wrong -- that these particular devices may capture Frame Based by default. But like you, I am not sure that this would necessarily produce the particular problem being discussed here. However, it could be worth trying to simply change the Field Order of the final project to Upper Field First, or even Lower FF if that doesn't work!!

Ken,

Like you, I used the 384 kps for Dolby 5.1 audio. The Dazzle device has me puzzled.., on what field order it uses. I have an old Dazzle, I think it is the DC10, that I haven't used since VS5 era. I don't recall what it captured to. I"d sell it on Ebay, except I think I'd have to pay someone to take it off my hands..

I do know there is no adjustment or flexibilty with them. So I would conclude that it does capture to Frame based.
