Here were a lot to sort out:<br>

The dvd-wide-ffmpeg+mpeg2enc.m2v from here is also
scaled or streched too high in vertical direction.<br>

In comparision the ffmpeg command
line I have used is:<br>
ffmpeg -i dv01.dv -f dvd -target
pal-dvd -aspect 16:9 -vb 8000k -mbd
rd -trellis 1 -cmp 0 -subcmp 2 -vf
crop=iw-0-0:ih-106-65:0:<br>
which results in progressive and DAR
16:9, but still not so good edge
quality<br>

and ffmpeg still encodes
interlaced-as-progressive, so VLC for example does
not enable deinterlacer at playback automatically?</div>

I hope this sum up of the 4 variants I get from Cin DVD creating,
using the current unpatched version:<br>
<br>
Input file: PAL DV interlaced 4:3<br>
Output DVD cropped to 16x9<br>
<br>
The dvd folder file names below are else descriptive <br>
<br>
Deinterlaced checked (di):<br>
<br>
1) mediainfo ./dvd_wide_cin_di-ffmpeg_20230608-184940/dvd.mpg | grep
Scan<br>
Scan type : Progressive<br>
<br>
2) mediainfo ./dvd_wide_cin_di_mpeg2enc_20230608-201519/dvd.mpg |
grep Scan<br>
Scan type : Interlaced<br>
Scan order : Top Field First<br>
<br>
<br>
Non deinterlaced (unchecked):<br>
<br>
3) mediainfo ./dvd_wide_cin_ffmpeg_20230608-203740/dvd.mpg | grep
Scan<br>
Scan type : Progressive<br>
<br>
4) mediainfo ./dvd_wide_cin_mpeg2enc_20230608-191936/dvd.mpg | grep
Scan<br>
Scan type : Interlaced<br>
Scan order : Top Field First<br>
<br>
Obviously 2) and 3) are wrong<br>
Are they fixed in the patched version?<br>
<br>
<br>
5) Which de-interlace filters are used in CinGG with mpeg2enc and
ffmpeg?<br>
<br>
I.e some users claims that Bwdif is better than Yadif for ffmpeg. <br>
