Converting DNxHD (Atomos) .mov files to mp4 issues

Kassim Massop
Dear community,

I have been using  ffmpeg to convert .mov files captured from my  Atomos
Ninja inferno for a few weeks now.

I recently recorded about an hour of footage in 4k resolution for the first
time and when I use the commands that normally work for me on lower
resolutions I get the below error.

My goal is to reduce the humongous file size to something more manageable
whilst keeping the quality high, I am a beginner user but I do have some
knowledge on how to use ffmpeg.

Command run - H:\FFMPEG-Convert\bin>ffmpeg -i 5.mov output.mov

To work around this error I ran the below command

- H:\FFMPEG-Convert\bin>ffmpeg -i 5.mov -c copy -strict experimental -c:a
aac -b:a 11520k output.mov

But then got this new error

Re: Converting DNxHD (Atomos) .mov files to mp4 issues

Kassim Massop
Thanks for pointing that out.

I actually thought I was on the latest build. I have no idea how I was on
this old one.

Conversion seems to be working now.

Thanks
