interlaced extras...

[fedge]

Im sure this may have been asked before. but i must be dumb my searching didnt find it. How do i deinterlace the extras (only the ones that need it ) without messing up the main feature and other progressive sources.

If you enable "Deinterlace with DECOMB" it will only apply to content flagged as interlaced.

There is a common problem with PAL discs where the progressive content is flagged as interlaced. In this case it is not possible for DVD-RB to automatically select the right method, instead it goes by the flag and treats everything as interlaced. You can enable "Disable 'interlaced'" to treat the whole disc as progressive, but if it is mixed content you would have to manually edit the files to get it right.

Hi-

Not only is this a problem with PAL material (extras or the main movie), but an equally big one with NTSC extras. Unless you've examined the DVD extras thoroughly prior to sending them through DVD-RB, and know what you're doing, you can mess things up in a really big way by deinterlacing.

For PAL, as wmansir stated, most of the time you'll have progressive material encoded as interlaced, and the last thing you want to do is to deinterlace it. As he said, unless there is some truly interlaced material, using the "Disable Interlaced" option would be much better. If you really want to deinterlace the interlaced parts, you might add FieldDeinterlace(Full=False) to the .avs Filter Editor. That way only truly interlaced material will get deinterlaced.

As for NTSC extras, frequently they are hard telecined. Already telecined originally film material is encoded as interlaced 29.97fps, and just deinterlacing that will give you a horrible "strobing" effect. Perhaps even more often you'll have a mix of interlaced material and hard telecined material. For example, many of the "Making Of" documentaries included as NTSC DVD extras have interlaced "talking heads" discussing the movie, interspersed with hard telecined clips from the movie. Deinterlacing the whole thing will also mess up a lot of it (the film parts), and it's debatable whether or not deinterlacing video (30fps interlaced material) is any improvement. Again, unless you're real sure of what you're doing, you would probably be better off leaving it alone to let DVD-RB reproduce it the way it's on the DVD originally.

If you want to apply a filter (such as a Deinterlacer) to the extras, or to some of the extras, then the Add-On for DVD-RB, RB-Opt, allows you to do that I believe.

Thanks i think that is the answer i was looking for but not "forward to"...
