Best Ways to Convert Video to DNxHD Losslessly

I have recently been looking for a good converter that can convert my video files into DNxHD (which many people say is fantastic for editing). The problem is that I can’t a free converter that does this. Any other suggestions?

Need to convert incoming video files to DNxHD to use in Avid Media Composer? Here we have 2 best methods to help you transocode video to DNxHD codec without quality loss.


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. It is still a lossy format so take that into account when choosing the bitrate, larger is obviously better, downside is the space requirement.

Option 1 – FFmpeg


Our research has shown that a number of answers lie in a cross-platform free open-source command line application called FFmpeg. However, there is a snag. With any command-line app, you need to communicate with it using text based commands in Terminal, which isn’t the most user-friendly interface. Take a look at this example, if you were to type this into Terminal…

ffmpeg -i ~/Desktop/Scripts/abc.mp4 ~/Desktop/Scripts/convertedabc.avi

With this instruction, you could take an mp4 file on the Desktop called abc.mp4 and convert it to an avi file called convertedabc.avi, but you have to get all the formatting of the text exactly right and all the characters have to exactly correct or at best it won’t work and at worst you can do serious damage, so not the easiest way to communicate with an application.

There is detailed information in the FFmpeg documentation and if you are comfortable with command line tools then this is a powerful set of tools.

Youtuber ‘0612 TV w/ NERDfirst’ has produced a video showing how you can use FFmpeg. This video consists of three main parts – Installing FFMPEG, some fundamental notes about how it is used, as well as some filters and effects it supports.
