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
ffmpeg –h encode=dnxhd gives the following:
General capabilities: threads
Threading capabilities: frame and slice
Supported pixel formats: yuv422p yuv422p10le yuv444p10le gbrp10le
-nitris_compat <boolean> E..V.... encode with Avid Nitris compatibility (default false)
-ibias <int> E..V.... intra quant bias (from INT_MIN to INT_MAX) (default 0)
-profile <int> E..V.... (from 0 to 5) (default dnxhd)
So I am unsure how to achieve a pixel format of yuv444p10le
I have been at this for days so if anyone can help I would be very grateful. I wonder if it is a bit rate setting but I can’t see what bit rate to use with the framerate and pixel format.
I hope this question makes sense
