Newbie Question about DV and Studio 8

[mercm3]

using Pinn Studio 8 I capture about 80mins of video to my hard drive(my son's football games) using the default settings for DV. Afterward viewing the raw AVI file i notice sometimes there seems to be jaggies when something moves on the screen. Thinking they would disappear when I created the DVD I went ahead and used Studio 8 to create my DVD complete with menu options(yeah I know not really a big deal but my first time hehe). Anyways those jaggies are still there in the DVD. I know when I play the camcorder directly to TV they are not there so I believe these jaggies are something i am introducing during the DV to DVD conversion. sorry question seems so general but anyone got any advice on this matter?

Your footage is interlaced -> intended to be watched on TVs.
If you want to create a DVD out of it you can keep it interlaced - software players (on PC) will perform some deinterlacing during playback. Just make sure to tell your MPEG2 encoder that it is getting interlaced content when creating your DVD.
Check the guide to learn about the whole process:

You should be a bit more specific when you talk about jaggies!

It could be interlacing artifacts, which you won't see on a TV. Since you are going DV all the way, then the field order should be right.

If you are constantly seeing "jaggies" on a TV, then I would guess that the field order has been screwed up. Everything that moves looks bad.

If you only see an occasional "jaggie", it could be caused by dropped frames, and appears as a jump in the motion of somthing that should be moving smoothly.

I have a question related to interlaced videos. If my DV source is interlaced and I do all settings in my encoder to generate interlaced Mpeg2 file for watching on TV's, this DVD (mpeg2) will be equally good while watching on PC, as PC supports deinterlaced video.
And the same question, if I convert my DV (interlaced) to DivX (that doesn't support interlaced) using deinterlacing feature while encoding, the generated DivX will play fine on my TV using the standalone player?

Thanks for all the advice guys I got it str8 now. Everythings all happy :)

Generally your DV source will be interlaced, if you taped it youself with a run-of-the-mill camcorder that is. If you have an expensive DV camcorder that can do 'progressive' video, then you should know quite a bit about interlaced/non-interlaced/progressive things anyway!

DVD players on a PC will usually incorporate a 'de-interlacer' on the fly, to mak stuff look better. Movies are filmed progressive, but newer straight-to-TV movies are taped interlaced. TVs are meant to handle interlaced, and are given two fields for every frame. For interlaced (eg: the news) they can be quite different. For progressive (eg: movies) they are generally very similar.

Going DVD (on PC) with a filmed movie looks as it should. A home video on a PC DVD player will not look quite the same as it did originally - because it is de-interlaced.

So your statement ...interlaced Mpeg2 file for watching on TV's, this DVD (mpeg2) will be equally good while watching on PC, as PC supports deinterlaced video... is quite wrong.

I beleive the later versions of DivX can encode interlaced. XviD has been able to for quite a while. Don't use them myself.

Your de-interlaced DivX will play fine on your TV (if you have the player that is!). However, it may not look as 'fluid' depending on your source.
