Converting MXF files to Apple ProRes 422 HQ generates no audio, video only. Why?

Hi,

Does anyone here have experience with Aunsoft TransMXF for Mac or Aunsoft Video Converter for Mac?

I was using Aunsoft TransMXF for Mac to convert my Cannon C300 MXF files to the Apple ProRes 422 HQ(*.mov) format so that I can import and edit my video footages without rendering in Final Cut Pro X.

However, the converted MOV file from Aunsoft TransMXF for Mac included no sound, only video (which was in excellent quality though).

I have played the generated Apple ProRes MOV file in both QuickTime and FCPX, no audio at all.

But the original MXF files just previewed fine with audio in the camera itself.

I am not sure if there's anything wrong with my MXF files or with the Aunsoft TransMXF for Mac program.

Any suggestion here is appreciated!

iMac, Mac OS X (10.6.8), NA

Just got the solution.

I contacted the customer service at Aunsoft and they offered me the workaround. Here shares the information so that people with similar issue could have a reference.

From Aunsoft:

Why Canon C300/XF100/XF300 MXF files converted with no sound?
If your MXF files from Canon C300/XF100/XF300, etc are converted with no sound, or your MXF files previewed in Aunsoft program with only video, please do not worry. It is because Canon MXF contains two audio tracks, one with sound but the other with no sound. Aunsoft TransMXF or Video Converter happens to pick the track without sound by default. This is the reason why the converted output will has no sound but only video.

No worries, here’s the solution for this issue:
On the main interface of your Aunsoft program, click the "Show selected task properties" button on top of the Format box and then select in the Audio Stream ID box a different audio track.
Then, you can play Canon C300/XF100/XF300 MXF files in the preview window with both audio and video.Meanwhile, the files converted will also be with sound.
