Re-wrapping MOV to MXF?

[Jason Johnson]

Hey Craig, It seems I have done the same thing as in this post and was wondering if you could explain the re-wrapping process after I have used fcp to export to the original Mpeg 4 format.. Is there a loss of generation doing it this way? I don’t quite understand what to do once I convert the file in fcp.. I see in the post that the next process is with the clip browser software.. but I don’t quite understand what i need to do?

[Craig Seeman]

Did you follow these instructions?

[Craig Seeman]

If so, all you are doing is changing the wrapper. The only loss would be if you actually did any compositing and transitions, etc. which always involves a bit of encoding/rendering.

In ClipBrowser 2.6 use the File/Import function to import the .mp4.
ClipBrowser will create a new BPAV.
Save that BPAV as your Master.
You should be able to Select the Clip and use Flie/Export/MXF for NLEs…
You’re just changing the wrapper
EXDCAM EX .MP4 .MOV .MXF are all the same “essence” with different wrapper and metadata handling.

Yes I did everything in the video procedure..I think I figured out what to do in the clip browser too but it seem this will be very time consuming..And when it is converted back to the bpav folder is it the same quality as the original? or is there loss?

[Jason Johnson] “.I think I figured out what to do in the clip browser too but it seem this will be very time consuming.”
Why time consuming? I take it you have lots of clips to do. I haven’t tried this with a bunch of clips.
I wonder if you can import a bunch of clips and do a “select all”

[Jason Johnson] “nd when it is converted back to the bpav folder is it the same quality as the original? or is there loss?”
As state above. It’s just a wrapper change and reconfig of the metadata. The “essence” remains the same.

So it is essentially the same data as was on the card? I don’t think it works as select all.. I called sony and was told to take multiple clips in a timeline then export but i think that will make one big clip and then i have concern about the timecode on the clips..

[Craig Seeman]

Yes if you put it all on one timeline you’d get one long clip. Sony really designed this for a one clip at a time workflow. It would be good if they had a batch method.

Great instructions! It doesn’t get anymore simple than that thanks so much. You Can also use this script my friend came up with in Apple Script Editor.

Copy and paste the following, but make sure you initially export your movies from a dual mono sequence

set the_movies to choose file with prompt “Choose your QuickTime files” with multiple selections allowed
set the_location to choose folder with prompt “Choose your export destination”
tell application “XDCAM Transfer” to export the_movies to the_location as MXF
