1. Use the defaults
a. DVD-RB doesn't convert NTSC to PAL (in fact I don't know of any process that will do it with satisfactory results).

2. VHS Quality? No, but you can set it for Half-D1 -- which is better than VHS but lower than standard DVD.
a. No. Generally deinterlacing is a bad idea. The only exception is for instances where the disc will only be displayed on a computer monitor -- and the playback software doesn't do interlaced playback very well.

jdobbs,

In regards to 2a. If it is going to be played back on a standalone DVD player that's connected to an LCD TV (progressive, of course), should de-interlace be used?

Stand-alones outputs deinterlaced material to progressive port; if you have a LCD you should have a progressive-capable player, so better not to deinterlaced unless cases like jdobbs mentioned to.

The question is whether is should be de interlaced for storage and the answer seems to be no, since it might cause artifacts.

Hardware deinterlacing seems the norm from new players?

EDIT: also i am wondering if capture hardware doesnt already de interlace upon capture.

Is retail DVD interlaced or full scene?

Generally you should never deinterlace except for very specific reasons under very specific circumstances. Deinterlacing attempts to smooth the differences between fields. On a truly interlaced souce the fields represent two different points in time -- and the picture will suffer as a result of attempting to "merge" them.

Hardware deinterlacing seems the norm from new players?No. They playback progressive souces as progressive, and interlaced sources as interlaced.
Is retail DVD interlaced or full scene?They vary.

jdobbs,

Deinterlacing for a computer is done because there are so many software players out there than just suck when it comes to handling interlaced sources. A high quality software player (like, for instance, PowerDVD) will play them back correctly even on the computer.

All standalone players are designed to properly handle interlaced sources.

A high quaility software player ... like PowerDVD ...Pity its observance of the DVD specs sucks so bad :)

Its a player, its suposed to allow for variance.

Also, the terms progressive and interlaced....Aint they similar things???

Progressive Jpegs and interlaced video.... there should be another term for full scene video?

for semantics, shouldnt the fields be two different points at the SAME time??

otherwise you get the flickers if they aint at the same time :D

:stupid:

No... that's exactly the point I'm making. The picture of the second field is the event that occurred 1/60th of a second later than the first field (assuming NTSC). Progressive sources may also have two fields -- but they both represent the same point in time. That's the main reason interlaced frames need to remain interlaced... so the fields are played back 1/60th of a second apart, like the recording. That's also why it is important to separate fields when you do certain filtering functions on interlaced sources.

I played a DVD which was intentionally authored badly (had a VM command in an inappropriate domain) and it just ignored it. A decent player would have stopped dead and told me something was wrong.

Scratch? No -it was an invalid command. Anyway, this is OT.
