CS5 just reads the native camera files. You don't need the clip browser. The MP4s are the files and the metadata comes in with the media...I don't know why they're annoying if they work... exporting to mxf would be a rewrap, but I don't know why you'd want to transcode...or rewrap for that matter.

I also don't know why QT files would be a problem if you have the codec. I've done some pretty long timelines of ProRes material on a PC in PPro...

Ok...chiming in here with the opposite problem...I think my system is too weak to edit T2i footage. :-(

Here's what I have:

Processor: Pentium 4 @ 3.2ghz
RAM: 2GB DDR2 (yeah, I know---at least 4 is better!)
Video: ATI Radeon X1950 (might be the Pro model?), 256MB DDR3 RAM
OS: Windows XP, SP3 (Yeah, I know—Win7 64-bit is better!)

Using Vegas Pro 8.0c, this system was good enough to edit SD-DV with no problems (though renders were somewhat slow)...but am I screwed for editing 1080p HD? LOL (How about 720p?)

Anyone else using such an old/slow system for editing?

Screwed...
yes :~(
Welcome to the money hole.

Mxf!
 

I use Vegas 9.e and have been transcoding my T2i files to Neoscene - big files.
In fact I have ignored MXF up to now.
But after reading this thread I made a litle test rendering some T2i files to Sony MXF and noticed that, beside the rendered MXF files are much smaller than the corresponding T2i files (great!), comparing them on the preview monitor, it seems that there was no video quality loss.
Is that possible or I`m making a wrong judgment (on no video quality loss)?
By the way, what is MXF used for?
Thanks
Ron

That would make more sense, thanks Steve!
