Andrew, after
many, many runs and actual DVD media
creation with these patches in, I am
almost certain that all is working well
and now there is the choice of creating
BFF media. So answer to question of "do
you still get interlaced" is "YES" as far
as I can tell. Here are some of the
results / differences seen when use
"mediainfo":
1) GOP,
Open/Closed :
Open -------------------> Before
GOP, Open/Closed of first frame :
Closed -------------------> Before
GOP,
Open/Closed :
Closed -------------------> After is
just this 1 line which makes sense
2) Scan type is
a little confusing though:
Before
-----> it always read Interlaced for
all, whether or not the Deinterlace box
was checked or not
After
------> if Deinterlace box is checked,
it reads Interlace
I think it should be set to
Progressive if deinterlace checked ....
Sorry, back to double-checking my
logic ..
It seems with m2ts source and deinterlace on
I get this mpeg2enc line:
Running
/data/data/com.termux/files/home/cinelerra/cinelerra-5.1/bin//mpeg2enc
-v 0 -b 8000 -q 1 -a 2 -F 3 -H -c -I 0 -M 8 -f 8 -g 15 -G
15 -R 0 -o
'/data/data/com.termux/files/home/tmp/dvd_20230609-161131/dvd.m2v'
no "-z" , also "I" equals zero
but mediainfo still says:
Scan type :
Progressive Scan order
: Top Field First
yet ffprobe says
Input #0, mpegvideo, from
'/data/data/com.termux/files/home/tmp/dvd_20230609-161131/dvd.m2v':
Duration: N/A, bitrate: N/A Stream #0:0: Video:
mpeg2video (Main), yuv420p(tv, bt470bg, progressive),
720x576 [SAR 16:15 DAR 4:3], 25 fps, 25 tbr, 1200k tbn
Side
data:
cpb: bitrate
max/min/avg: 8000000/0/0 buffer size: 1835008 vbv_delay:
N/A
I was dumb I selected pal 4:3 instead of pal
16:9 in dvd master ....
So, may be this is bug (o-feature) in
mediainfo?
Anyway, those parameters can be changed if
you click on wrench icon on video (mpeg) stream in
second-stage window where batch files already set up.
After
------> if Deinterlace box is NOT
checked, it reads Interlace IF input is
interlaced BUT Progressive if input media
is not interlaced.
Does the above
make sense? (I think I stated it
correctly).
In the DVD media I
tested on a really old non-digital TV with
a DVD player, the BFF media looked about
the same as the TFF media, even when
original media was BFF or TFF. But the
old TV was so bad looking, that I am not
sure it was a good test.
Playing Interlaced
DVD media on a new digital TV with a DVD
player, looked decent but that is probably
due to the software in the digital TV.
Playing DVD media
on a new digital TV where the original
input was interlaced and CinGG had the
Deinterlace box checked, did result in
some small jagged areas but mostly visible
only when stop or step.
RECOMMENDATION: if
not editing the input media so you do not
need an NLE, i.e. CinGG, probably should
refer to ffmpeg, dvdauthor, or those
forums that apply direct copies of media
exclusively for creating DVDs.
Can you clarify
even with my patches AND
deinterlacing checkbox set in
dvd creation window and "use
ffmpeg" unchecked you still get
interlaced?
Confusing
results that I did not consider.
I will thoroughly investigate
"before and after" tomorrow and
let you know what is happening.
(I should have done this earlier).
