Exporting from Premiere to DVD...

[mountainman]

I am exporting video from MiniDV that I capped to HDD and then exporting to DVD. When I do so, the video looks very "jaggy". Anyone do this? If so, do you recommend an export setting?

Thanks.

Pics of jaggies? That may be the easiest way to help, but I'll take a stab at a couple things.

What resolution are you exporting your video from Premiere at? If it's DV, it should be 720x480 for NTSC, which is the exact same resolution your DVD authoring program should be exporting it to. If it's any different, then you'll get some sort of aliasing on your video.

Are the jaggies just interlaced lines? Perhaps your DVD authoring program isn't detecting the source as being interlaced?

Hi Jim...I didn't explain well. :)

I capped miniDV video and edited it in Premiere. After that, I chose to export to DVD. I used the default setting and it was very aliased. You can usually just see it at big color changes and also during faster motion (running, etc). It looks almost ghosted?

Thanks for any help. I apologize for not being able to explain better.

Can you provide any visual samples of what you describe? That would be the quickest and easiest way to diagnose your problem.

Without a picture, my guess would be that it has to do with deinterlacing. Here are a couple links which may or may not help you fix, or at least understand the issue:

Which format was the original capture?

[mountainman]

When it captures, it does so in AVI.

Jim: I looked thru them and they are quite jaggy like those that have not been deinterlaced. I am not too knowledgable on what video does when it goes from AVI to MPEG4 (DVD, right?).

I'll be opening up the program again tonight and will try again.

:)

Thanks!

I'm just guessing, but it sounds like the video is still interlaced, and either Premiere or your DVD authoring program isn't (properly) deinterlacing it.

When you convert your video into a DVD-compatible format (MPEG-2), all it is doing is compressing the video to a certain spec, it doesn't modify it in any other way. So if the source video is interlaced, the final product will be interlaced as well. However, most DVD programs should be able to detect and flag the video as being interlaced, and the DVD player should display the images without those lines. The fix may be as simple as just changing a setting to deinterlace the video.

I'm planning to try that tonight. I got busy last night with other stuff.

I'll let ya know!
