You can specify each value but this is easier, for example -pix_fmt=yuv422p10le. vf is as alias for -filter:v and creates the filtergraph that is used to filter the stream. Note that the pix_format must match the profile! The above list was adapted from DNxHR codec.

DNxHR 444: dnxhr_444 - Finishing Quality.DNxHR SQ: dnxhr_sq - Standard Quality.I was stuck at this point for a while until I found a post on askubuntu explaining that a different profile was needed.ĭnxhd: The lists of available/possible resolutions can be looked up here, but they do not go bigger than 1080p. I was able to convert 1920x1080 videos but kept getting an error when attempting 4k 3840x2160 videos. profile:v defines the profile to use for the video.Īccepted values are: dnxhd, dnxhr_444, dnxhr_hqx, dnxhr_hq, dnxhr_sq, dnxhr_lb. c:v (or the alias -vcodec) defines the codec to use for the video That sucks…So this is why we have to convert the audio when we convert the video. Referring back to the Black Magic Support Codecs, we see that mp3 and AAC are not supported in either free nor Studio Linux version. This is pretty simple, as described in this tutorial instructions.įfmpeg -i input.mp4 \ -c:v dnxhd \ -profile:v dnxhr_hqx \ -vf "scale=3840:2160,fps=24000/1001,format=yuv422p10le" \ -b:v 110M \ -c:a pcm_s16le \ output.mov Audio Transcoding My goal was to preserve the highest resolution and quality during the conversion or “transcode” to work with in DR16. Handbrake is a GUI front-end to ffpmeg and is awesome, I’m sure it could do it but I wanted something that I could run from a shell script and I wasn’t exactly sure what it was doing under the hood. Linux will read mp4 in DR16 Studio only.Windows will read mp4 in DR16 Studio only.macOS will read mp4 in both DR16 (free version) and DR16 Studio (paid version).In the support notes of DR16 it states that : My goal is to edit and color correct my home videos in Davinci Resolve 16 ( DR16) but it turns out it doesn’t import these GoPro video files directly, at least not in the Linux free version.
