Re: [FFmpeg-user] Convert images to DNXHD 444
Hi Guys. I am waiting for some test footage I can share because I have since discovered that creating YUV444 might not solve my underlying problem. This started when I generated a yuv422p10 DNxHD and the colours were different to the original tiff sequence (saturation down). I assumed it was due to it not being 444 but in fact a quicktime generated through Quicktime API produces "perfect" DNxHD with no discernable colour difference to the original MOV. I spent a day searching for an answer but nothing made a difference. Like I say I will upload some examples as soon as I can get them, maybe tomorrow. But I would also like to be able to generate DNxHR 444 and hqx as well.

Apart from being unmaintainable and outdated, I removed the frame-rates from the help text of the encoder because I couldn't find a player that refuses "invalid" frame-rates.
