Leaving it dvd rendering interlaced is worst jagged; selecting
deinterlaced is better both with default mpeg2enc ("TFF,
interlaced") and optional FFMpeg (progressive). Some of the
jagged edges and lines is expected to be caused by the scaled up
low vertical SD wide resolution.<br>
I didn't notice visible +/- chroma difference by selecting "use
yuv420p dvd deinterlace format"<br>
<br>
I will try to compare with DeVeDe's deinterlace YADIF filter and
two pass rendering.<br>
(DeVeDe's second FFMPEG deinterlace filter exited the dvd
rendering.)<br>
<br>

<br>
In comparision with Cin rendering, the DeVeDe dual pass with YADIF
deinterlacing did compress the movie_0.mpg more and it was
verified as progressive. All progressive dvd video qualities were
visual comparable.<br>

Regarding Dvd Interlaced Chroma:<br>
Possibly PAL dv 4.2.0 is more pleasant for MPEG-2/DVD 4.2.0 than
NTSC dv 4:1:1 (?</blockquote>

Add also two references to the latter:<br>
