Lately I have experimented with PAL DV to DVD rendering, both using ffmpeg/DeVeDE, and now using CinGG mpeg2enc/FFMPEG I hope someone can help to clarify the following questions and debug possible issues regarding DVD Rendering with CinGG: 1. dvd.m2v and dvd.mpg Why are there two video files created, dvd.m2v w/o Audio and dvd.mpg w/Audio, and which one is used for what? tree -sh dvd_20230528-115747 dvd_20230528-115747 ├── [ 16M] dvd.ac3 ├── [3.4K] dvd.jobs ├── [562M] dvd.m2v ├── [588M] dvd.mpg ├── [ 733] dvd.sh ├── [6.5K] dvd.xml └── [4.0K] iso ├── [4.0K] AUDIO_TS └── [4.0K] VIDEO_TS ├── [6.0K] VIDEO_TS.BUP ├── [6.0K] VIDEO_TS.IFO ├── [ 18K] VTS_01_0.BUP ├── [ 18K] VTS_01_0.IFO └── [588M] VTS_01_1.VOB 2. Deinterlacing: The input PAL DV source file is Interlaced, Bottom Field First ffprobe: Stream #0:0: Video: dvvideo, none, 25000 kb/s, SAR 16:15 DAR 0:0, 25 fps, 25 tbr, 25 tbn Stream #0:1: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s Unsupported codec with id 24 for input stream 0 mediainfo: Width : 720 pixels Height : 576 pixels Color space : YUV Scan type : Interlaced Scan order : Bottom Field First Why does deinterlacing with dvd default rendering (mpeg2enc) still come out as Interlaced, but Top Field first? ffprobe -hide_banner dvd.m2v Input #0, mpegvideo, from 'dvd.m2v': Duration: N/A, bitrate: N/A Stream #0:0: Video: mpeg2video (Main), yuv420p(tv, bt470bg, top first), 720x576 [SAR 64:45 DAR 16:9], 25 fps, 25 tbr, 1200k tbn Side data: cpb: bitrate max/min/avg: 8000000/0/0 buffer size: 1835008 vbv_delay: N/A ffprobe -hide_banner dvd.mpg [mpeg @ 0x55a756c7af00] start time for stream 0 is not set in estimate_timings_from_pts Input #0, mpeg, from 'dvd.mpg': Duration: 00:09:56.44, start: 0.160000, bitrate: 8305 kb/s Stream #0:0[0x1bf]: Data: dvd_nav_packet Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, bt470bg, top first), 720x576 [SAR 64:45 DAR 16:9], 25 fps, 25 tbr, 90k tbn Side data: cpb: bitrate max/min/avg: 8000000/0/0 buffer size: 1835008 vbv_delay: N/A Stream #0:2[0x80]: Audio: ac3, 48000 Hz, stereo, fltp, 224 kb/s Unsupported codec with id 98312 for input stream 0 mediainfo dvd.m2v | egrep "Color|pixels|Scan" Width : 720 pixels Height : 576 pixels Color space : YUV Scan type : Interlaced Scan order : Top Field First Color primaries : BT.601 PAL mediainfo dvd.mpg | egrep "Color|pixels|Scan" Width : 720 pixels Height : 576 pixels Color space : YUV Scan type : Interlaced Scan order : Top Field First Color primaries : BT.601 PAL While corresponding deinterlacing with the optional FFMPEG DVD Rendering comes out as Progressive? ffprobe -hide_banner dvd.m2v Input #0, mpegvideo, from 'dvd.m2v': Duration: N/A, bitrate: N/A Stream #0:0: Video: mpeg2video (Main), yuv420p(tv, bt470bg/unknown/unknown, progressive), 720x576 [SAR 64:45 DAR 16:9], 25 fps, 25 tbr, 1200k tbn Side data: cpb: bitrate max/min/avg: 9000000/0/0 buffer size: 1835008 vbv_delay: N/A ffprobe -hide_banner dvd.mpg [mpeg @ 0x561effba3f00] start time for stream 0 is not set in estimate_timings_from_pts Input #0, mpeg, from 'dvd.mpg': Duration: 00:09:56.42, start: 0.160000, bitrate: 8266 kb/s Stream #0:0[0x1bf]: Data: dvd_nav_packet Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, bt470bg/unknown/unknown, progressive), 720x576 [SAR 64:45 DAR 16:9], 25 fps, 25 tbr, 90k tbn Side data: cpb: bitrate max/min/avg: 9000000/0/0 buffer size: 1835008 vbv_delay: N/A Stream #0:2[0x80]: Audio: ac3, 48000 Hz, stereo, fltp, 224 kb/s mediainfo dvd.m2v | egrep "Color|pixels|Scan" Width : 720 pixels Height : 576 pixels Color space : YUV Scan type : Progressive mediainfo dvd.mpg | egrep "Color|pixels|Scan" Width : 720 pixels Height : 576 pixels Color space : YUV Scan type : Progressive 3. Dvd Interlaced Chroma With reference to the CinGG manual https://cinelerra-gg.org/download/CinelerraGG_Manual/Dvd_Interlaced_Chroma.h... /Now you can use the YUV420P DVD Interlace Mode when rendering DV directly to mpeg2 through a yuv4mpeg stream and when using video effects on HDV video./ /With this option enabled, improved chroma results will be obtained from your DV or HDV source. Editing DV or HDV and rendering it back to the same format does not require any special handling. In order to perform colorspace conversions correctly in CINELERRA-GG and avoid Chroma errors for interlaced 4:2:0 video, check the box as follows:/ Settings → Performance → YUV420P DVD Interlace Mode I can't find this option and is it relevant for DVD rendering? 4. Missing FFMPEG output According to the manual: https://cinelerra-gg.org/download/CinelerraGG_Manual/DVD_Bluray_Creation.htm... I/t is also highly recommended to run the CINELERRA-GG startup from a terminal window, instead of the icon, in order to see informative messages of how to actually write the output (at prompt: keyin <install_directory_path/bin/cin). / For the default mpeg2enc DVD rendering there is output like mpeg2enc -v 0 -b 8000 -q 1 -a 3 -F 3 -H -I 1 -M 8 -z t -f 8 -g 15 -G 15 -R 0 -o '/home/terje/Videoklipp/DVD/dvd_mpeg2enc_20230527-184531/dvd.m2v' For the optional FFMEG DVD Rendering it would be nice to also get the actual "ffmpeg code line" as terminal output, both for learning, customizing and debugging. Is that possible ?
