Simple utility for non-destructively trimming clips?
 

Does anyone know of any good tools for non-destructively editing the mp4 files? I generally record long clips and trim them in post to the good stuff, but can't find a great way to do that right now. Can vegas do an MXF output without re-encoding? Is there any super simple editor that I could run on a laptop to do the split by proxy?

Thanks in advance!

Vegas can output MXF.
Also, using clip browser you can select in and out points and import that as a new clip, then just rewrap that.
For example, if you had a long wedding ceremony but wanted just the bride coming up the isle then you can select just that part of the long clip, you'll get a new short clip then as well, then you can just export or rewrap that small clip.

Just used the XDCAM explorer for the first time and it is exactly what I was looking for, thanks for the tip. And it plays back on my netbook!?! Amazing!
