Are you saying that you can open the native mp4 file in vegas, without rewrapping to mxf ?

I just tried and vegas can't open the files, i have to rewrap to mxf first.

You know what? I just tested this to be sure. You're right. I cannot. My transition to using the .mp4 files came at the same time as my transition to another editing codec. The transcoder can read those files just fine, but Vegas cannot.

I am sorry for the confusion.

whew, I thought it was ALL my equipment screwing up!

are you still using clip browser to re wrap then?

i've updated the laptops clip browser to v.2 and can now pull the files off the SDHC card, but its still slow...what am I missing? is it possible its camera related?

No, USB is slow. That's why the cards come out and can be placed in a machine. It's also that slow USB interface that is responsible for us not being able to do overcranking on SDHC. No way around it unless you want to take the card out and transfer directly.

No, I don't.

There is a utility that converts mp4 files to Avid's DNxHD codec directly, in batch. So I just point it at all my source material, and let it do it's thing. When it's done, I have lovely editable files. Overnight, I do the same thing, but let it encode to higher quality files (if necessary).

Peronne, out of interest what utility are you using?

A small utility called XDCAMEX_to_Avid. It's a GUI shell wrapped around ffmpeg. Takes mp4 files as input, kicks out DNxHD .mov files. Simple and highly effective.

thats what I did this time, and I stopped the transfer at 12 minutes in to a 7 min file.

I just tried copying my BPAV folder from my expresscard to my laptop drive. 7.03GB took about 2 minutes 20 seconds.

now you are just showing off! haha.

that was with the express card plugged right into the computer? did the drive come with the computer? or did you buy it aftwords?

I am gonna go try my gear with a mac, just to rule out the camera, and go from there.

EDIT-

just noticed you said laptop, so I am assuming its a newer one with the built in express card slot huh? I need to find an adapter for my PCexpress card slot, so I can try using the SxS cards.

Many of the SD card slots on laptops do not support SDHC cards without a firmware update. I had this problem on a Vaio. Found I got much faster transfers from SDHC cards by using a USB to SDHC adapter.

Yes, I bought the new laptop in anticipation of working with the EX1. Ordered within a week of each other. Honestly, if you are going to get into this level of the game, the workflow has to be solid end to end.

I'm specing out a new desktop as I type this. Hopefully a dual quad-core. One of those times I WISH Vegas would use a GPU. But I am building this one to handle 2k and 4k. I don't want to be here again in 2 years crying about my slow machine.

yeah, my laptop is the weak link, but the desktop shouldnt be, its all brand new, built specifically to handle the ex3.

back to the BPAV subject, how do you re wrap using clip browser? I put the folder on the desktop as a test, and cant find it using clip browser.
