<[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.

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. Now,
seemingly ".qt" tells me it means "quick-time" (not qt gui)
cat dv_pal.qt
mov dvvideo

A dv vs dv50 squiz:
DV: yuv420(pal) - ca, 25Mbit/s (video) - 25 FPS
DV50; yuv422 - ca 50Mbit/s (video) - 25 FPS
I have also read that DV50 may be interpreted as 2 DV streams in parallell.
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

Frame rate : 50.000 FPS

Is the latter Separated fields 2 interlaced fields each odd and even
lines that simulates a progressive 50 FPS video?
