1 quick question about TMPGEnc

[Beautiful Alone]

on step 2/5

on video type, what is non-interlace and interlace?

and field order, what is top field first[field A] and top field first [field B]?

[Tommyknocker]

Remember when you read the Newbie Guides and it said this:

Non-Interlace: It encodes your movie so that it does not have interlaced pictures... A interlace picture is a picture that has 2 picture per frame and if you remember back when I was talking about Frames Per Second I said it doubled itself, well frame A is half of the picture starting with the top line and the skipping the next then shows the one after that.

The B half of the frame puts in what frame A missed, so when the frame rate is doubled you get the full picture and also your 60Hz of NTSC or 50Hz for PAL. Ok now this encoding method doesn't do this it puts frame A and B together to make frame A then doubles it to get a exact copy for frame B. Using this makes a source progressive.

Interlace: Ok this one does what I said above It encodes a 29.976 non interlaced movie to shows half the frame in frame A and half in frame B. This is for converting to 29.976FPS from a 23.976FPS movie with the help of 3:2 pulldown under the advanced tab.

You did read them right?

so, which one is better to choose from?

If your talking about the advanced tab than there is no better or worse...you are simply telling the encoder the nature of your source. To find out whether your source is interlaced or progressive (non-interlaced) you can preview it in dvd2avi.

As far as the encoding mode which you set on the video tab, this is a decision you have to make depending on your source and what you are trying to do. If your encoding in mpeg1 you don't have a choice since mpeg1 does not support interlacing.

If your encoding in mpeg2...

If your source is progressive than keep it that way unless you have a specific reason not to.

If its pal interlaced then keep it that way.

If its 29.97fps (ntsc) interlaced than either keep it 29.97fps interlaced or do an inverse telecine (which converts the framerate to 23.976fps) and keep it progressive (the inverse telecine removes all interlacing leaving you with a progressive source.)

As to whether progressive or interlaced is better, there really is no answer for that, they are just different.

Hi, how do i find out if my source is progressive or not? thanks.
