Is it legal? Mixed PGC of interlace and progressive cell.

[jinjin_jp]

DVD which I created have the pgc which have the cell of interlace and progressive because of some reason.
Is it legal ?

The reason ; TV broadcasting in Japan changes to digital from analog in near future. When analog, it shows warning about changes in beginning of program.
I often capture TV and create DVD of music. The warning is ugly and obstructive. So I want to delete it.

Processing ;
In this case, actual movie is 16:9 and the position of warning is out of movie. I utilized it.
(1)capturing TV and authoring once (it is 4:3)
(2)split ugly part by VobBlanker
(3)demux ugly part to video and audio by PgcDemux
(4)crop top&bottom and convert to 16:9 video by MediaCoder.
(5)convert to the video of 4:3 of which top&bottom is black by DVDFlick.
__(it needs to set "pixel aspect ratio" to 16:9 from usually default.)
(6)remux converted video and original audio by MuxMan.
(7)replace ugly cell to remuxed vob by VobBlanker.

But output of (4) is progressive and originai is interlace.
So there is mixed the cell of progressive and interlace.
Is it legal?

Is it legal ?
I didn't understand all that you wrote, but to answer your main question, yes, it's perfectly legal. It's also quite common to mix progressive sections with interlaced sections in a DVD. It happens all the time with anime DVDs. As long as it outputs 29.97fps, it's NTSC DVD compliant.

Thanks for the answer.
Sorry, my English is bad.

I created DVD like below. Is it legal?

Title_1 (PGC_1)
cell_1 : progressive
cell_2 : interlece
cell_3 : progressive
cell_4 : interlace

I want to one more question.
Is ot legal?

Title_1 (PGC_1)
cell_1 : first 15sec is progressive, later is interleaved.
cell_2 : first 15sec is progressive, later is interleaved.

Regards.

As I already said, you can mix progressive and interlaced content. Cells have nothing to do whether or not it's OK. About the only stipulation is that it must output 29.97fps. If some is encoded as progressive 23.976fps, pulldown must also be applied.

Thanks for the answear.
I can create DVD without worry.

Output is surely NTSC and 29.97fps.
