ProRes (or DNxHD).mov to .MXF for Vegas w/ffmpeg

Eagle Six wrote on 2/11/2016, 3:47 PM

When I run astar's ffmpeg command line as (that he posted in another thread):

ffmpeg -i t001.mov -vcodec copy -acodec copy t001.mxf

I get this error:

[mxf @ 0000000002ed0200] Unsupported video frame rate 30000/1

The input is ProRes422HQ. MediaInfo reports this is 29.970p. Is ffmpeg expecting a frame rate of 30p?

Can anyone provide insight or a solution?

This is the full screen readout:

This is the original file MediaInfo:

Thank You and Best Regards.....George

Don't know about the error message specifics but you cannot go directly from MOV to MXF with a file that has a stereo audio stream. The audio stream needs to be split into separate mono streams. That was mentioned in the other thread and there was an example command given to handle this but you seem to have overlooked that.

I'm not sure the ffmpeg muxer accepts Prores in MXF files. I've never tried it. The ffmpeg MXF muxer is pretty finicky.

Here is a batch command I have used to remux XDCAM mpeg-2 in MOV to MXF. It worked for that. Don't know about anything else. It works drag and drop from the file browser, for any number of input files.

@echo off

:top
c:\systools\ffmpeg\bin\ffmpeg.exe -i %1 -c:v copy -c:a pcm_s16le -filter_complex channelsplit=channel_layout=stereo[FL][FR] -map 0:v:0 -map [FL] -map [FR] "%~dpn1.mxf"
if errorlevel 1 goto error

shift
if NOT %1$==$ goto top
goto :EOF

:error
echo !!! error encoding !!!
pause

Not all codecs are supported in the containers. You can copy Prores into .AVI, but then Vegas does not have a codec to read it. Quicktime reads the Prores codec, and QT is .MOV in Vegas.

If you add an -r 30 to your command, you would get an error saying the container is not supported.

Same pretty much goes for DNxHD. DNxHD is supported in .MXF. You can convert ProresHQ 10-bit to DNxHD 10-bit in an mxf container using FFMPEG. Vegas does not know what to do with the format however.

There are several versions of MXF and you pretty much need to be a member of SMTPE to access the specifications to understand the refined differences.

If you are trying to get to something equal to ProresHQ, try Resolve and render to MXF OP1A - Sony MPEG4 422 (225Mbs) or (450Mbs) depending on the specifics of the Prores stream. This will maintain the Prores file qualities and put you in an MXF format Vegas is optimized for.

Vegas will convert limited amounts of .mov and .mov below a certain size. If you work in those boundaries, you can convert to HDCAM-SR or XAVC-I.

astar posted the string on my post:

-acodec pcm_s24le -ar 48000 -newaudio -map_audio_channel 0:1:0:0:1:0 -map_audio_channel 0:1:1:0:2:0

did you try this?

As others have stated, you cannot put ProRes in an MXF container. In the original post you were referring to iPhone QuickTime files which are AVC/H.264 which you CAN out in an MXF container. So this doesn't work for all codecs, only those codecs that can be placed in an MXF container.

You will need to re-render ProRes files if you don't want to (or cannot because of Vegas Pro limitations) work with them as QuickTime files. CineForm AVI is a good digital intermediary to convert them to.

Thanks for all the replies, I appreciate the time and effort, it's starting to sink in (maybe, somewhat!!).

-------------
I rendered with Resolve 12, MXF OP1A - Sony MPEG4 422 (225Mbs). I get a Vegas crash when adding the file to the media bin:

I know enough about Resolve to be dangerous, I'll try a few more render options.

-------------

I did try the -acodec line and ffmpeg reported:

Unrecognized option 'newaudio'.
Error splitting the argument list: Option not found

However, if I understand this, as mentioned, if ProRes will not go into an MXF, then the -vcodec copy isn't going to work anyway.

Again, Thanks for the time and insight, it provides me with some things to try and alternatives.
