Also, when decoding an interlaced video x264 tells the player the video is interlaced. When decoding a progressive video x264 tells the player the video is progressive. That way the player knows whether it should display the two fields separately or together.

* There are various techniques used for deinterlace processing from a simple blend, to previous and post frame interpolation.
OK now this is the thing?
I get what you told me most Apple devices can show Prograsive videos and this is what Handbrake was for.
But Most DVDs are Prograsive if they are Films that is.
So when you take a Prograsive video and then ad a De Interlace Option to it you are giveing a Prograsive video another Prograsive encode.
And even if you set De Interlace to OFF Handbrake will still tell H246 it is a Prograsive vido and it will then be encoded as Prograsive.???
HDTV sets, DVD/Blu-Ray players and the new generation of media players support a wider range of formats. Almost all support interlace or progressive DVD. You yourself said your player plays DVD VOBs fine.
So you are doing all this because you want a smaller file or just want to understand the options?
You said your MPeg2 VOBs played OK didn't you? I'm assuming this applies to both "Land of the Lost" and "Buck Rogers".
You are asking here for a 500 kbps AVC encoded, quality reduced alternative to DVD VOB. To do that you need to identify the DVD format before you convert it to AVC.
So, how is that "Land of the Lost" encode playing on your player. Can you see any difference compared to the VOB play?

First things first.
Handbrake does a good job of converting to MP4 and they play ok.
I understand now that H246 is just compressing the video that is all it does everything like making it Interlaced or Prograsive is a job for Handbrake or whatever other program you use.
I know if I pick any of the De Interlacing options from the Dropdown list that is the type of De Interlacing it will aply to the video.
But if I pick OFF in the De Interlace dropdown list it will give it a De Interlace Weave and it does this because it must give it some kind of De Interlacing so it can give it to H246.
Ok I get all of this Handbrake must always give Prograsive video to H246 not that H246 can't compress Interlace it just is that Handbrake can't give anything but Prograsive.
Ok so I get all this so if I open a DVD of a Movie I know what you would tell me.
You would tell me a Movie is already Prograsive so you don't need to De Interlace it.
Ok I get that but even if I pick OFF from the De Interlace Dropdown list Handbrake will still give it a De Interlace Weave.
Ok so even if I don't pick OFF in the Dropdown list the other setings Fast Slow Sloest are all other types of De Interlacing as well.
And I don't want to give it any of them as well.
So would you not say Handbrake is not for taking in Prograsive video?
H.264 (MPEG-4/AVC) is the video format
MP4 is the file container.
x264 is the h.264 compression codec that Handbrake and most other "free" programs use.
x264 can encode progressive or interlace. Handbreak just uses the progressive features.
Handbrake is primarily a user interface that sits atop several other process functions (e.g. x264 and the various video/audio filters). It was the decision of the Handbrake writers to only support progressive video output (h.264 or MPEG-4 FFmpeg or VP3). They did this because they were mostly targeting media devices and cell phones, many of which can't process interlace video.
x264 encoder but Handbreak always tells x264 that the video is progressive even if it is interlace.
Deinterlace (off, fast, slow, slower, custom)
Decomb (off, default or custom)
Detelecine (off, default or custom)
If your DVD is Progressive (soft telecine) set everything to OFF. It is already Progressive. Other similar programs would give the option to convert 23.976 fps progressive (soft telecine) to 29.97 fps interlace (hard telecine).
PS: In the NTSC DVD world the only "progressive" option is 23.976 fps (soft telecine). But it is possible to disguise other types of progressive as interlace (e.g. hard telecine, 29.97p, 24pA etc). These are processed as interlace.
