Progressive all the way? at DVinfo.net

2 beginner's questions:
If I output my progressive clips to normal interlace DVD and I don't have a progressive DVD player, would I still get the film look when watching from normal interlaced TV?

Do I need to do everything in progressive from capture to display in order to get the film look?

Thanks.

For what I've heard is that the progressive frames on your DVD-disk are converted to interlaced by your DVD player, which in turn sends the signal to you interlaced TV.

You WILL get the film like motion, because the two fields that are generated by your DVD-player have the SAME frame as a source. Because of this your content will have 25 fps (for PAL) or 30 fps (for NTSC)

When you play an interlaced DVD-disk, the DVD-player wil also output even and odd fields, but now they are different because the source is interlaced (which causes the smooth video-ish motion)

I think you can capture your progressive footage in interlaced mode on your PC. As long as you don't explicitely re-interlace your video, your computer will capture the same video as if you selected "Progressive" in your NLE (this is true for Premiere and I suppose it's also true for other NLE's)

AVI files cannot exist of even and odd fields (just frames), so there wouldn't be a difference between capturing with the progressive setting on or with the interlaced setting on, because the output is an AVI file and AVI's are always progressive.
