HELP !!! Interlace or NOT to Interlace , that is the quest??

[arcorob]

I have Hi8 films captured to 720 by 480 AVI files. USe Video Factory to produce final AVI.

Now take TMPG and Setup to build MPEG 2 for SVCD.

Here is the question that is SO UNLCEAR.

On SETTINGS
VIDEO TAB
Encode mode defaults to Interlace
Advanced TAB
Video Source Type Defaults to Interlace

Is this correct ??? WHat is the difference. I know how frames are interlaced but my question is , ARE THESE SETTINGS correct ? I want to get a CLEAR , NON-MOTION blurred SVCD and play on tv

Help is VERY greatly appreciated

I think you mean "hi8 tape", not "hi8 film". There is no such thing as "hi8 film".

Leave settings as they are. Use maximum bitrate you DVD palyer can handle, of which I think you should be aware, if you don't want artifacts.
Why, it's a long , long story....

A PC monitor “draws” the image from top to bottom one line after another. This is non-interlaced.

A TV “draws” the image every other line from top to bottom and goes back to fill in the skipped over lines from the first path, hence it’s interlaced.

What this means to you is, if you are making a video for TV, then leave it interlaced. If you are going to make it for PC viewing, convert it to non-interlaced.

If you view an interlaced video on a PC monitor it will look jagged, especially during fast moving shots. This is due to the two fields of interlacing are slightly out-of-sync to compensate for the interlacing of the TV.


Hope this helps...

The setting in the "Advance" tab is for the source video and this tells TMPG how to handle the source. Since your hi8 captures are interlace you will want to make sure "interlace" is selected here, and for "field order" you'll have test encode a small segment to determine the order.

In the "Video" tab this affects the output MPEG file only. Since you're making SVCD, and SVCD can be either progressive or interlace, it's always best to match the source. In this case you should choose "interlace". The setting basically tells the player how to treat the SVCD as either 'frame' base or 'field' base I believe.
