Please Help My Jaggies

I just can't eliminate them, particularly if the image moves or if I pan the camera. I get jaggies on areas of the image.

I capture using VidCap with the frame rate set to 25.000 PAL

Project settings are 720 x 576
Frame Rate: 25.000 PAL

Field order: Lower field first
Pixel aspect ratio: 1.0926 PAL DV

Render quality: Best
Motion blur type: Gaussian
Deinterlace method: None

I thought project settings only apply to edits and renders, not to the timeline playback of unedited material but I get jaggies as soon as I capture anything and play it from the timeline.

Is there a magic formula for this?

It sounds like you are talking about your preview panel!

the timeline playback of unedited material but I get jaggies as soon as I capture anything and play it from the timeline.

Then set your preview panel to best or are you talking about rendered content?

You are seeing interlacing artifacts, which is perfectly normal when viewing interlaced material on a progressive display like a computer monitor. These "jaggies" won't be there when you view your material on a display which handles interlacing properly, like a television..

If you are rendering to a progressive format, you will want to choose a deinterlace method, generally "interpolate" works best. In fact, you probably want to set the deinterlace method to anything other than "none" even of you aren't rendering to a progressive format.

Thanks John

I was hoping for a magic setting that would remove them from the preview window (the edit preview not capture preview).

If my better half is watching over my shoulder she blames it on me! I'll send her round to your place next time. ;~)

Try setting your preview quality to "Preview-Auto"

Regarding sending you better half over here, I can't possibly see that as being a good idea. :)

Thanks John.

I invariably have the preview quality set to "Preview-Auto" because 'Good' and 'Best' make the jaggies look worse.

Regarding sending my better half over there, I couldn't afford the ticket anyway. :~(

I usually render slideshows as progressive because uprezzing DVD players do a much better job of uprezzing the non-interlaced image.

25p PAL can look very good for slideshows.
