Choose the bitrate depending on how good quality you need for whatever you need to do with the DNxHD video, the bigger bitrate the more space the output video will take.Įxample commands for converting to DNxHD with FFmpeg Examples Description The output DNxHD frame format (Resolution and FPS) must match the video format of the source, so make sure you choose a suitable format from the above table.įor example if your input video is a Full HD 1920x1080, 25 FPS then you can choose output bitrates of 120, 185 or 46 Mbps. The ffmpeg output format must match precisely one of the DNxHD profiles below: DNxHD profiles for Full HD, 1920x1080 DNxHD profiles Frame sizeĭNxHD profiles for HD, 1280x720 DNxHD profiles Frame size DNxHD also is very strict about video frame size, pixel format and framerate. DNxHDĭNxHD support Full HD (1920x1080) and HD (1280x720) frame sizes only. This way obviously leads to much larger files, meaning you need quite a lot of disk space for the converted videos. It is still a lossy format so take that into account when choosing the bitrate, larger is obviously better, downside is the space requirement. DNxHD is a more editor friendly format as every frame is compressed separately instead of relying on previous frames and therefore the editing software can easily seek frame accurately in the video without need to decompress any intermediate frames. For example, the common h264 and h265 encoded videos produced by most devices (phones, GoPro, etc) will be imported with audio only under Linux ( In version 15 and 16).įortunately the solution to this issues is quite simple, even if a bit space and time consuming, by converting the video files to a DNxHD or DNxHR with FFmpeg. It supports various professional video codecs, but unlike consumer editors it does lack in support for consumer video formats under Linux for some reason. The "Basic" version is available for Linux, Mac and Windows environment for free. DaVinci Resolve is a professional video editing application by BlackMagic Design.
