Hello, I made a video whose length is 1h10 and I want to put it on a DVD. I will use mpeg2enc to encode the YUV4MPEG stream produced by Cinelerra. I already used mjpegtools some time ago, and I just looked into my notes in order to find the syntax I used in the past.
Here is what I plan to use now: nice -19 cat ./test.yuv | /usr/local/bin/y4munsharp | /usr/local/bin/yuvmedianfilter -T 3 -t 0 | /usr/local/bin/mpeg2enc -v 1 -n p -a 2 -r 32 -4 1 -2 1 -g 12 -G 15 -F 4 -B 256 -b 7500 -f 8 --no-constraints -o test.m2v The picture is jerky. =( When playing with mplayer the yuvstream output by cinelerra, the following information is displayed : YUV4MPEG2 file format detected. Unknown stream tag encountered: 'C420jpeg' YUV4MPEG2 Video stream 0 size: display: 720x576, codec: 720x576 VIDEO: [YV12] 720x576 12bpp 29.970 fps 0.0 kbps ( 0.0 kbyte/s) Xv: could not grab port 58 ========================================================================== Opening video decoder: [raw] RAW Uncompressed Video VDec: vo config request - 720 x 576 (preferred colorspace: Planar YV12) VDec: using Planar YV12 as output csp (no 0) Movie-Aspect is 1.37:1 - prescaling to correct movie aspect. VO: [xv] 720x576 => 786x576 Planar YV12 Selected video codec: [rawyv12] vfm: raw (RAW YV12) The DVD will be distributed to a lot of people. I spent more than 300 hours organizing the footage (four cameras where used at the same time) and editing the video. I want the encoding to keep the image quality at its best. And what I get is a video which displays perfectly on my computer, and whose pictures are jerky on my standalone player. =/ Could you please help me? I read the docs, I read the mailing lists archives. I tried to use the -I option. I tried without the -g and -G options. I tried with -F 3, and the problem is still there. =( Thank you.
