4 a) Cin-GG Loaded a PAL 1080i/50 HDV clip Set Format Preset: PAL 576i (16:9) - DV(D) File Render File Format: FFmepg - avi (NB! because plain Raw DV still causes DAR 4:3) Audio: Preset: avi_pcm_s16.avi Video: Compression: dv_pal.avi
For me it looks like the Set Format Preset: PAL 576i (16:9) - DV(D and/or the File Format: FFmpeg make up the correct DAR 16:9 here, right?
Because by Selecting the Format: *Raw DV *cause rendering to *DAR 4:3* as shown below ! This makes me wonder if it is only the FFmepg File formats that currently is fixed by patches? May also other non-FFmpeg formats be affected by anamorphic aspect ratios ?
This is possible! I basically never used non-ffmpeg video encoders! I think we have 3 of them - raw dv, mpeg video and theora video.
I'll check each of them.
What about DVD Render (16:9) and BD Render from HDV source? Are they for example quite independent of the Set Format Preset?
I think yes .... I'll look into that too.
I have successful tested two cases DVD Render to iso from HDV source. In both cases the Audio seemed to be locked to AC3 codec. It could have been of interest to just copy without reencode/recompress the compliant MP2 audio from the HDV source. 1) Format PAL (25.00) 16x9 and default (mpeg2enc) Stored and displayed seemingly correct with DAR 16:9 and full image (not cropped) du -sh * 12M dvd.ac3 4,0K dvd.jobs 395M dvd.m2v 413M dvd.mpg 4,0K dvd.sh 8,0K dvd.xml 4,0K iso ffprobe -hide_banner dvd.mpg [mpeg @ 0x5591efbbe580] start time for stream 0 is not set in estimate_timings_from_pts Input #0, mpeg, from 'dvd.mpg': Duration: 00:06:58.08, start: 0.160000, bitrate: 8269 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, 50 tbc 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 100357 for input stream 0 2) Format PAL (25.00) 16x9 and FFmpeg Stored and displayed seemingly correct with DAR 16:9 and full image (not cropped) du -sh * 12M dvd.ac3 4,0K dvd.jobs 387M dvd.m2v 404M dvd.mpg 4,0K dvd.sh 8,0K dvd.xml 4,0K iso ffprobe -hide_banner dvd.mpg [mpeg @ 0x559cbd650580] start time for stream 0 is not set in estimate_timings_from_pts Input #0, mpeg, from 'dvd.mpg': Duration: 00:06:58.08, start: 0.160000, bitrate: 8100 kb/s Stream #0:0[0x1bf]: Data: dvd_nav_packet Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, bt709/unknown/unknown, top first), 720x576 [SAR 64:45 DAR 16:9], 25 fps, 25 tbr, 90k tbn, 50 tbc 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 Unsupported codec with id 100357 for input stream 0
