It is good the way you have it. Before the patch, when progressive media was input and the Deinterlace box was NOT checked, "mediainfo" always displayed "Interlaced, Top Field First". Mediainfo is not always 100%.
Phyllis; In comparision, how is the video detected with ffmpeg -filter:v idet http://www.aktau.be/2013/09/22/detecting-interlaced-video-with-ffmpeg/

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).
