Hanssen via Cin <[email protected]>: I have made another working ffmpeg command line without "-target pal-dv50" as seen below, and tried here to make a video preset for CinGG , but got errors and have questions: A related example: Is it a reason why Cingg preset for DVD doesn't use "-target pal-dvd" that I have used with ffmpeg before? I am not sure if this is 'composite' command line switch for ffmpeg as command line application or you can use it in our profiles. try and tell us now it works?Not sure I understood what you meant here. But I did base my FFmpeg command line on presets from WinFF, i.e for "PAL DVD HQ Fullscreen": -f dvd -target pal-dvd -aspect 4:3 -vb 8000k -mbd rd -trellis 1 -flags +mv0 -cmp 0 -subcmp 2 As seen above, this WinFF preset make use of the related "-f dvd -target pal-dvd" https://www.mail-archive.com/[email protected]/msg05766.html In comparison Cingg's preset doesn't use ffmpeg's dvd target *I think* -target just set bunch of parameters at once. So not really needed if you set them individually in preset. cat dvd.dvd dvd mpeg2video s 720x480 r 30000/1001 pixel_format yuv420p g 18 maxrate 9000000 minrate 0 bufsize 1835008 packetsize 2048 cin_bitrate=8000000 --------------------------dv50_pal.mov mov dvvideo # cin_pix_fmt=yuv422p # cin_scale=720x576 # r=50 there is ffmpeg/video/dv_pal.qt try it?Yeah, thanks for this tip which looks good, interesting and promising ;) I noticed also this preset, but didn't bench test it.

But what happened by selecting framerate 50 fps in CinGG, when ffprobe above say 57600 kb/s, 50 fps and mediainfo below say Overall bit rate : 117 Mb/s Bit rate (video) : 24.4 Mb/s Frame rate : 50.000 FPS Original frame rate : 25.000 FPS Scan type : Interlaced !!? Scan type, store method : Separated fields (2 fields per block) Is the latter Separated fields 2 interlaced fields each odd and even lines that simulates a progressive 50 FPS video? sorry, no idea here.Depend on your source and Project settings it probably still means interlaced, because we do not do auto-deinterlacing, or fields to frames conversion.Watch output file frame by frame, I think it will remain interlaced.Yes, I stepped frame by frame with VLC, but as this was a rather static video recorded with the camera on a fixed table stand, I have to wait until I later to try playback of real things with movments.My camcorder sources are all 50i no doubt. What confuse this workflow, is the ms2130 capture card that captures progressively, not 25fps but 50fps as actual in this case. And next the dvvideo codec is fundamentally interlaced.So when mediainfo say 50 fps and scan type/store method is separated 2 fields per block, the remaining doubt is if this in effect will be 100i fields in sequence or make possible "parallell fields playback/displaying at once" (dependent of devices) ....Or said in another way, while dv50 no doubt offers better color 422 recording than DV, the doubt is if the 100Mbit/s+ bit rate offers no benefits but waste of space, compared with plain dv50 at 50Mbit/s fps (though unobtainable here)....
Or jump to and continue with what I first thought; keep it progressive in output,
