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>

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 class="moz-txt-link-freetext" href="http://cinelerra-cv.wikidot.com/cincv-manual-en:rendering-files#11">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>
<a class="moz-txt-link-freetext" href="https://www.qsl.net/n1gg/linux/video/linuxdvdguide.html#3">https://www.qsl.net/n1gg/linux/video/linuxdvdguide.html#3</a><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>
<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>
