I have been trying to understand ffMPEG and outputting a file with the DNxHD codec.

I keep getting an error [swscaler @ 0x7feec601a200] deprecated pixel format used, make sure you did set range correctly

Here is what I've been working with:

ffmpeg -loop 1 -i image.jpg -i audio.mp3 -shortest -c:v dnxhd -b:v 120M -s 1920x1080 -pix_fmt yuv422p -r 25 -c:a pcm_s16le -ar 48000 out.mov

But I was wondering if it was possible to make an AvidDV SD version of the output? 1024x576 or 720x576 at 25fps? I know you can make other codecs, but an Avid one would make for fast import.

deprecated pixel format used

This is a warning, not an error, and you can ignore it.


The FFmpeg DNxHD encoder only supports valid DNxHD profiles. ffmpeg will output the list if you attempt to output unsupported width x height, frame rate, bitrate, and/or pixel format. Or view the list at another answer.


FFmpeg can output DV, but I'm not quite sure why you would want to. This is an old format and there are better, modern, lossless alternative intermediate formats for editing such as UT video (ffmpeg can encode and decode that too). Like DNxHD it will only output certain DV profiles, but it can use the -target option to make it arguably easier to use:

ffmpeg -i input -target ntsc-dv output.dv
  • Understandable to the codec choice, but we are using SD footage and there is no need to import HD, as it is to be muxed to DVD. With the above, would this work: ffmpeg -loop 1 -i image.jpg -i audio.mp3 -shortest -target pal-dv -c:v dnxhd -b:v 120M -s 1920x1080 -pix_fmt yuv422p -r 25 -c:a pcm_s16le -ar 48000 out.mov or would the mix between the DNxHD and DV be wrong?

  • @Ahhhhhhhhhhhhhdfgbv No, that won't work. -target options are vcd, svcd, dvd, dv, or dv50 with optional prefixes pal-, ntsc-, or film-. To generalize, it's only useful for encoding to DV and DVD formats.

  • Understood. I may go for the -target pal-dv50 or -target dvd as the output would be DVD anyway
