Is it possible to get the mpeg2enc command line to test it with a dv
input file directly outside Cinelerra?
try line like this?
ffmpeg -i input.dv -f yuv4mpegpipe - \
|mpeg2enc {flags and output file as shown }
Yes, this fixed the BFF issue, but still Interlaced and 4:3 format.
Stream #0:0: Video: mpeg2video (Main), yuv420p(tv, bt470bg, bottom
first), 720x576 [SAR 16:15 DAR 4:3], 25 fps, 25 tbr, 1200k tbn
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.
quite amazing ffmpeg in this most basic case still works after nearly
20 years, line stolen (and modified) from
https://avva.livejournal.com/1188593.html
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
http://cinelerra-cv.wikidot.com/cincv-manual-en:rendering-files#11
and is also included in Ruh's dvd guid sec. 3.4
https://www.qsl.net/n1gg/linux/video/linuxdvdguide.html#3
mpeg2enc is said to give some higher quality at high bitrate that ffmpeg.
The drawback is it is slow and audio and to be added and multiplexed
For ffmpeg as I said cingg does NOT use command line ffmpeg, so you
need to modify profile parameters in dvd.dvd file.
And preferably also a corresponding ffmpeg command line.
I had already created a .mpg video file, interlaced and bff, and
it was
no better, so I think deinterlaced (progressive) will be best.
your call!
Happy coding!
