E.T. - Progressive or Interlaced?

[wulf109]

I'm confused over the subject of progressive or interlaced. When I scan the vob in Bitrate Viewer it says it's frame=interlaced,but if I scan the vob in DVD2AVI it says frame=progressive. Which one is correct and does it matter? I've never been able to frame-serve a vob file at resolutions higher than 352x240 and get good results. At higher resolutions I either get severe stuttering and comb lines or both.
Does progressive=noninterlced? I find that if I encode in Tmpeg SVCD non-interlaced the picture looks,to my eye,sharper then when I encode interlaced.
Does a high resolution monitor,600-800 lines,display non-interlced better than interlaced?

23.976 progressive = noninterlaced

PC monitors display progressive data

Films are nativly progressive

Encoding progressive will result in an overall better picture and a better output on a PC monitor.


If you are getting "combing" you are seeing interlacing due to telecine or hybrid materal. TMPGenc has an excellent IVTC to restore the original progressive signal if the movie is encoded "hard" telecine ( ie the video signal has been altered ). THe majority of US titles are "soft" telecine that can be fixed by using DVD2AVI's force film setting.

If in doubt search for more info.

When I say high resolution monotor I'm referring to a TV monitor not PC.

Standard TV's are interlaced and the "lines of resolution" is mostly a bogus number. Encoding a truly progressive mpg generally improves the quality only due to inreasesd consistancy between adjacent pixels in a progressive encode.

If you are talking a TV with Componient input and progressive display combined with a progressive DVD player then yes, it would make a signifigant difference.

Most films released to theaters are progressive. ET was a theatrical release, so it originated as progressive film. If you scanned the first .VOB in BitrateViewer, then you may have scanned the studio header / FBI warning, which are usually interlaced, and BRV doesn't continually update its info.

Always - I repeat - always, scan any .VOB but the first to get the true nature of the video. Use DVD2AVI to get the correct nature of the video. If I was a betting man (and I am) I would lay 10 to 1 odds that this is a PROGRESSIVE FILM video. Any takers?

Are not all films released to theater progressive ?

You are corect,I scannned the first vob in Bitrate viewer. When successive vob's it says progressive.

I am almost 100% positive that they are... however, I didn't want to get "flamed" by stating that as an "absolute" while missing that "one" exception that someone may know about.
