Deinterlace with avisynth, should i check progressive scan in Docce4u ?

[emilius256]

Hi everybody,
i read many posts on this forum about cce, deinterlace and the Big3 (wow, great job guys) but probably i'm too dumb to understand.
If i understand well if a dvd is progressive i must check progressive scan in DoCCE4U (automatically check zig-zag scan) and uncheck top field first.
If a dvd is interlaced i must uncheck progressive scan and top field first (unless the dvd is bff) and check alternate scan.
Now the part i don't understand well, if i deinterlace a dvd for example with FieldDeinterlace(blend=false) or with SelectOdd(), this became progressive, so i have to encode like progressive dvd (check progressive scan only), am i right ?
The same is if i inverse telecine a dvd ?
Sorry for my dumb question (until yesterday i believed that if a movie is top field i had to check top field first in CCE, result to dvd burned gone good for coaster) and thanks.

if its progressive..then it doesn't matter if you have top field checked or not since progressive doesn't use fields.

me personally i don't deinterlace because in some cases it makes the picture look worse - it may look better on a computer monitor if you choose to deinterlace but on a TV you cant tell the difference.

that has a lot of people confused - i was too at first.

If you have deinterlace on in your avs script, your source becomes progressive and can be encoded like that.

Don't know about telecide, since I almost only do PAL.

I've done a couple of interlaced movies with the "Top field first" checked in DoCCE4U when doitfast detects the stream as interlaced tff (I've also controlled that they are interlaced with virtualdub). The result has always been choppy on standalones. Now I've tried to uncheck the checkbox in DoCCE and the result has been perfect.

its actually backwards...if the source is interlaced tff...then you DON'T have to check top field first - only when its bff that you'll have to check it - confusing :confused:

Yup, hendrix is right.

Check CCE FAQ (http://forum.doom9.org/showthread.php?s=&threadid=53770) (Question 10) :)

servus...

Maybe BBWoof should "fix" this misinterpretation :)

But it seems all developers are very busy at moment

Sooner or later, DoCCE4U will correct this :)

Thank you for your fast answers.
But my problem wasn't about top field first (after many broken dvd i've learn the lesson), the question was about when deinterlacing in avisynth if i have to encode as progressive or as interlaced movie.
Influenza answered to my question (probably my message have some misunderstanding 'cause of my bad english) however i thank you all for take time to answer to my dumb question.
So at end, if i deinterlace or IVTC a movie in avisynth, i have to encode this movie like progressive.

Thank you all.
bye

Yes, the setting of progressive checkbox is determined not by source, but by what the final product will be. Most other settings in CCE are the same way.

Thank you.
