Hi Wayne
Can you expand on that a little, or perhaps give me an example based on my command line. Sorry but I am a little un-familiar with ffmpeg.
Thanks for the response.

ffmpeg -r 23.976 -i
C:\Users\Matt\Desktop\Newfolder\104_0020gn_01_X1_0%3d.tif -c:v dnxhd -profile:v dnxhr_444 -s 1920x1080 -r 23.976 -y C:\Users\Matt\Desktop\Newfolder\bt.mov

This creates a file similar to quicktime export setting: 1080/23.976 DNxHD
444 10 bit

ffmpeg reports
Supported pixel formats: yuv422p yuv422p10le yuv444p10le gbrp10le

So in fact I don't really want to create DNxHR but DNxHD 444 format. I would have thought that could be possible?


It is possible but the 440 profile isn't valid for 23.98fps material - you should be using DNxHD 350x for 10-bit 4:4:4 RGB @ 23.98fps. The DNxHD 440 (8-bit) and DNxHD 440x (10-bit) are only valid at higher frame rates, such as 29.97p, 59.94p and 60p

Hi All
I have been trying to convert an image sequence (16 bit tiff) to DNXHD
444. It can be done with Quicktime pro on Windows but I have completely
failed with ffmpeg.

ffmpeg -r 23.976 -i
C:\Users\Matt\Desktop\Newfolder\104_0020gn_01_X1_0%3d.tif -c:v
dnxhd -profile:v 3  -s 1920x1080 -r 23.976  -y
C:\Users\Matt\Desktop\Newfolder\bt.mov

Your -profile is wrong.  Try:

-profile:v dnxhr_444
