Is it possible to get the mpeg2enc command line to test it
with a dv <br>
input file directly outside Cinelerra?<br>

Yes, this fixed the BFF issue, but still Interlaced and 4:3 format.<br>
Stream #0:0: Video: mpeg2video (Main), yuv420p(tv, bt470bg, bottom
first), 720x576 [SAR 16:15 DAR 4:3], 25 fps, 25 tbr, 1200k tbn<br>
<br>
What I want is to get and try Progressive and 16:9 wide format. By
cropping 720x576 to 720x405, bottom 65 and top 106 (top) preserves
the displayed timestam at bottom.<br></div></blockquote></div></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">Then you should try ffmpeg's deinterlacing and cropping before passing it to mpeg2enc.</div></div></blockquote></div></div><div dir="auto"><br></div><div dir="auto"><a href="http://macilatthefront.blogspot.com/2021/05/which-deinterlacing-algorithm-is-best.html?m=1" rel="noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer" target="_blank">http://macilatthefront.blogspot.com/2021/05/which-deinterlacing-algorithm-is-best.html?m=1</a><br></div><div dir="auto"><br></div><div dir="auto">talks about some algos on ffmpeg I never considered:</div><div dir="auto"><br></div><div dir="auto"><h3><span style="font-size:21.06px">Estdif / </span>Bwdif</h3><div dir="auto"><div dir="auto">TS. bwdif V->V Deinterlace the input image.</div><div dir="auto"> TSC estdif V->V Apply Edge Slope Tracing deinterlace.</div></div><div dir="auto"></div></div></div></blockquote></div></div><div dir="auto"><br></div><div dir="auto">this one page talks about znedi3 neural network deinterlacer (need vapoursynth and nerves to debug, apparently)</div><div dir="auto"><br></div><div dir="auto"><a href="http://wp.xin.at/archives/5287" rel="noreferrer noreferrer noreferrer noreferrer" target="_blank">http://wp.xin.at/archives/5287</a><br></div><div dir="auto"><br></div><div dir="auto">mentions bwdif line like this:</div><div dir="auto"><br></div><div dir="auto">-vf bwdif=”mode=send_field:deint=all:parity=bff”<br></div><div dir="auto"><br></div><div dir="auto">next forum recommend</div><div dir="auto"><br></div><div dir="auto"><a href="https://forum.mrmc.tv/viewtopic.php?t=1615" rel="noreferrer noreferrer" target="_blank">https://forum.mrmc.tv/viewtopic.php?t=1615</a><br></div><div dir="auto"><br></div><div dir="auto">"Whenever I do any off-line deinterlacing in ffmpeg I use the video filter "w3fdif=complex:all" these days."</div><div dir="auto"><br></div><div dir="auto">And shotcut users found sometimes even "pp" subfilter may work.</div><div dir="auto"><br></div><div dir="auto"><a href="https://forum.shotcut.org/t/technical-discussion-interlacing-revisited/8311">https://forum.shotcut.org/t/technical-discussion-interlacing-revisited/8311</a><br></div><div dir="auto"><br></div><div dir="auto">Note, I might be not fan of adding deint permanently exactly because field still not reached absolute maximum quality.

Creating DVD with typical ffmpeg decoding to raw video piped to
mpeg2enc for encoding has been the usual way as described in the
Cin-CV manual <br>
<a href="http://cinelerra-cv.wikidot.com/cincv-manual-en:rendering-files#11" rel="noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer noreferrer" target="_blank">http://cinelerra-cv.wikidot.com/cincv-manual-en:rendering-files#11</a><br>
<br>
and is also included in Ruh's dvd guid sec. 3.4<br>

<br>
mpeg2enc is said to give some higher quality at high bitrate that
ffmpeg.<br>
The drawback is it is slow and audio and to be added and multiplexed<br>

And preferably also a corresponding ffmpeg command line.<br>

I had already created a .mpg video file, interlaced and
bff, and it was <br>
no better, so I think deinterlaced (progressive) will be
best.<br>
