Handbrake: Feature request: Support DNxHR as source

Created on 31 Aug 2017 · 15Comments · Source: HandBrake/HandBrake

DNxHR is the successor of the already supported DNxHD.
It is a frequently used intermediate codec which supports 4k resolutions (unlike DNxHD).
Supporting this codec would make it possible to convert 4k output of any NLE with Handbrake.
Otherwise you rely on the limited NLE exporting options.

Upstream Enhancement

A Cineform HD decoder has already been added to Libav master. HandBrake is currently on Libav release 12, so presumably this will become available with release 13, whenever that is.

Thanks for the request. This is actually dependent on our upstream decoder, Libav. HandBrake will gain support for DNxHR when it gains support.

Will leave this open to track any updates.

Is the same is true for supporting GoPro Cineform as an input?

as ffmpeg already supports DNxHR it should come with realisation of replacing libav with ffmpeg (#974)
Cineform is supported in ffmpeg since 2016

menaceone on 9 Apr 2018

@menaceone Should be fixed then; #974 is closed with the switch to ffmpeg completed.

Yes, please try the latest nightly build to verify DNxHR support. Will leave this open pending feedback.

Hey Guys,
awesome work with that ffmpeg replacement.
I did some tests.

I was able to open all sorts of DNxHR and Cineform files.
Cineform works like a charm.

Unfortunately HandBrake didn't recognize any audio tracks in the .mxf containers of the DNxHR files.
"MediaInfo" shows the correct audio tracks in the .mxf containers, therefore I assume the source files are correct.

Thanks much for testing this and providing the comprehensive feedback.

Any chance you can provide a small sample MXF for troubleshooting the missing audio issue?

bradleysepos on 3 Jun 2018

Want to post a log for those audio issues?

Also, I do wonder if the multi-track audio weirdness is also resolved or if it's still many mono tracks.

sr55 on 3 Jun 2018

What does "ffmpeg -i input" show for one of the mxf files?

cehoyos on 3 Jun 2018

@bradleysepos
here is a .mxf sample. For file size reasons it is a short 1080p, DNxHR LB 8bit file (~10MB)
link

@sr55
In Adobe Media Encoder (AME) you can set the audio option separate mono tracks.
It's disabled by default. I tested files with this option enabled and disabled, there was no difference in track recognition in Handbrake.

you mean the HandBrake activity Log for the .mxf file scan?

@jstebbins Do you have time to look at this? Sample in previous post.

bradleysepos on 3 Jun 2018

I'm about out of time today, and next week I need to focus on some real job issues. Not sure how much time I'll have, but there's a good chance I can do some digging in the evenings.
