digital breaking up on effects/DVD Architect recompression

[Groucho]

Oh: I should add that the digital break-up is really only present AFTER burning the movies to DVD and watching them.

I can see it a little bit on the files themselves after the render, but not anywhere near as bad as it is after the burn.

thanks,
Chris

Hi Chris,

I’ll take a wack it.

[groucho] “1) After the track motion correction a nasty digital “break-up” is introduced ONLY in the areas of the moves where effects were used.”

More info please. Do you mean that you have added effects and now have problems that you did not have before moving the frame with track motion? If so, what effects are you refering to?
We may have a field order problem here but send more info.

[groucho] “2) DVD Architect is STILL saying that the files need to be recompressed”

When you render out your project in Vegas, select DVD Architect Video Stream as your template. The default settings are fine. This will render out a video stream that DVD Architect will not try to recompress unless your project is to large to fit on your DVD. You will also need to render out a Dolby AC3 stereo file using the same file name as your mpg video file. As long as you give it the exact same name DVD architect will find it automatically when you bring in the mpg file.

Last, DVD Architect will have to render out your background image that you create for your Menu. It will also create the needed files types to create your DVD.

If you are new to DVD Architect you may want to google DVD Architect Tutorial.

Hope this helps, Regards, Rick.

Thanks for the help Rick.

All the effects were added when I edited the movies originally with Windows Movie Maker. I didn’t do any further “effecting” with Vegas.

Everything looks fine until I move the frame with track motion and then render the file for authoring – then the “break ups” appear.

I’ve experimented with rendering WITHOUT doing the track motion adjustment and it’s fine – except of course that I’m missing 10% of the screen, so I know it’s not the rendering process that’s introducing the artifacts.

I’ve also tried using a constant bitrate instead of the default variable, but that – if anything – makes it worse.

I also happened to notice that the digital weirdness happens where there are some kind of effects in the movie – fade-ins, fade-outs, slo-mo, that kind of stuff.

Does this help clarify? I very much appreciate your assistance.

On the bright side, I did figure out #2 – I was just using the wrong template. So that one’s solved at least.:)

thanks!
Chris

Chris,

Your description helps a lot.
I have seen this problem before on some of my projects.
Welcome to the NTSC Interlaced Video World.
Whenever you repoisition your video frame using Track Motion or
Pan/Crop it is a roll of the dice as to wither you land on an
odd or even field. Land on the wrong one and you can get breakup or
a soft image. All that is needed is to open your project back up and
go into track motion, move the image up one field by pushing the up
arrow up key one time. It might be a good idea to zoom way in to the window
before up arrow up. You are barely moving the frame. The reason you
do not see the problem in your preview windows is that your computer monitor
is progressive scan unlike a TV which is interlace scan.
Render out a short section after you make the adjustment. If it works you are
in business. If not you might try reversing the field order completely in
your project settings and matching that with your render settings custom tab.

Let me know how it comes out.

Later…Rick.

I’ll give it a shot – thanks mucho Rick!

Shoot – I tried both your suggestions, Rick but unfortunately I’ve still got the digital weirdness happening.

Anything else I should try?

thanks,
Chris

Chris,

Are you sure that you actually moved it. In some cases you have to first click on the image in the track motion window before up arrow click.

Let’s try this. We will deinterlace your project. If this works you do have a interlacing field order problem, if it does not work something else is going on.

Open your project properties, video tab, select “none progressive scan”
in the field order box. Then render out a short section progressive. To do that select custom button after you have selected your type of render and template. In the video tab you will see a dropdown box with the option to render progressive, select progressive. Now render and see if that gets rid of your breakup. A test DVD would be a good way of viewing unless you have an External Video Monitor.

[groucho] “I have rendered them from WMM as DV-avis,”

Just for grins, click on your explorer tab in vegas and right click on one of your WMM-avis and select properties. Can you copy and paste that info into a post. I would like to see the specs on one of those clips.

Thanks…Rick.

[Groucho]

Hey Rick:

Yep, tried the “progressive” solution – no dice. The digital guck remains as long as the resize in track motion remains. Without the track motion step everything renders dandy.

I’ve definitely tried moving the field around, and I even tried doing the whole operation in pan/crop to see if that would make any difference. Nada.

I’ve pasted the file properties below. Maybe there’s a clue in there?

again, thanks much for your help Rick –
Chris

Chris,

I downloaded your clip (very cool).
When I play it back on my external video monitor it looks great.
When I adjust frame with either track motion or pan/crop the movement
gets a bit strobish. Just out of curiousity, why are you try to adjust the
frame? It looks great straight up.

I played around with it for a few minutes. Your field order is best set to lower. I tried a Manual reduce flicker on your clip, looked pretty cool, kinda like the star trek warp effect.

I will play more with it later.

How about taking this to my personal email, we are taking up space on the forum and no one else has chimed in.

I know I’ve asked for a lot of info, thanks for your patience, but I have a few more questions.

The clip that you posted, was that an export from the vegas timeline or was that one of your source clips. If it was a source clip it had been edited.
Can you tell me the history of the clips creation.
