Ah, pix_fmt was not working.... pixel_format=yuv420p was right choice .... still in some opt files I can see cin_pix_fmt yuv420p for example in /usr/share/cin/ffmpeg/video/faststart_h264.mp4 so, what exactly I should use - pixel_format or cin_pix_fmt? Attached video opts files I saw as working .... ---------- Пересланное сообщение ---------- Тема: Re: [Cin] utvideo options file Дата: Понедельник 28 октября 2019 Отправитель: Andrew Randrianasulu <[email protected]> Получатель: "Cinelerra.GG" <[email protected]> В сообщении от Sunday 27 October 2019 19:50:47 Phyllis Smith написал(а):

Andrew: interesting testing. We will add the 3 opts files of utvideo.qt, r210.qt, and v210.qt -- you never know who might want them. As far as pixel formats go, you would not believe how "smart" the correlation between CinGG and ffmpeg is. In the Video wrench for qt menu, there is Pixels textbox field with a down arrow. When you click on that down arrow to the right, it is so smart that it shows you the legal pixel formats.

Yes, but first format there usually codec default, not something from opt file? So, If codec enumerates them starting from yuv411 (as dv codec does) and I said yuv420 in opt file - I can still pick up right format, but it will be one more manual step? Try to leave default choise and see with that pix format file will be encoded? Sorry for additional testing load :/ may be pix_fmt is not working anymore in opt files?

just trying various codecs ...

...

mov utvideo pix_fmt=yuv444p threads=2 ... Also, I think strange codec called

v210 is still missing,

...

... also there is r210 Uncompressed RGB 10-bit ... but I haven't added pixel formats info ....

r210 seems to demand gbrp10le

and v210 accept yuv422p10le or yuv422p, so I think v210 should use yuv422p10le ?

Legal pixformats for utvideo are: gbrp, gbrap, yuv422p, yuv420p, yuv444p Legal pixformats for v210 are: yuv422p10le, yuv422p Legal pixformats for r210 are: gbrp10le
