Hi Jim,
you can use FFMBC.

It’s a command line utility that can rewrap your AVID MXF into Quicktime. You can download the windows version of it.

In fact it can convert almost any format into other.

There’s a paper I found that has instructions of how to convert any file into AVID quicktime:

6143_encodingforavidwithffmbc120114.pdf.zip

But your issue is simpler, because both files use the same video codec.

I do not have a AVID MXF file for testing but the command should be aproximately this:

ffmbc -i input.mxf -vcodec copy output.mov

The command line above does not have options regarding audio ou video tags that can be necessary for a successful conversion, but it’s a start point.

In my case, I use it to rewrap (not convert) Vegas XDCAM422 MXF files to Quicktime XDCAM files. I Use this command:

ffmbc -i input.mxf -tff -vcodec copy -vtag xd5b -an -threads 8 output.mov -acodec pcm_s24le -ar 48000 -newaudio -map_audio_channel 0:1:0:0:1:0 -map_audio_channel 0:2:0:0:1:1

where:
-tff means “top field first”

-vcodec copy means that the output file will use the same codec

-vtag xd5b means that the output file shoul be marked as 1080i60

-an means “audio none” i.e. it tells FFMBC not to copy the source audio

-threads 8 tells FFMBC to start 8 process simultaneously (which can accelerate the whole process). My machine has 8 cores, so this is the logical choice

-acodec pcm_s24le is the audio output codec

-ar 48000 is the audio output sample rate

-newaudio opens a empty audio output stream

-map_audio_channel determines how the input audio channel should be routed to the output.

This last option demands an explanation:
In this case, it takes the mono audio 1 of the input (stream 0.1, channel 0 or 0:1:0) and route it to the left channel of the output (0:1:0)

Respectively, it takes the mono audio 2 of the MXF (stream 0.2 channel 0 or 0:2:0) and route it to the right channel of the output (0:1:1)

I hope this helps.

Regards
