transfer times of SxS files (ex1 or ex3)
I’m considering purchasing either SxS memory type camera or P2 type camera. I’m curious as to the “card to edit” time with the SxS media. This means, if I have 50 minutes of footage (at 35Mbps) that will take up 16 GB of card. If I plug it into my MBP:
1. how long will it take to copy the contents of my card to the hard drive?
2. how long will it take FCP to “import” the footage (convert into editable quicktime files)?-trevor ward

If you use the Express slot of a MBP it download some 6x. You download a 16GB card in 8 minutes or so.[Trevor Ward] “2. how long will it take FCP to “import” the footage (convert into editable quicktime files)?”
The files are ready to be imported and edited in FC. No extra step needed.

Really? I thought the files that come off the SxS card are some sort of MXF files that need to be converted before FCP can edit them.

Hi Trevor,
The files inside the SxS are MP4.
When you download them, they can be “re-wrapped’ as QT or as MFX.
I guess the MFX is for PC use.
I don’t know how works thing in PCs.
In the Mac you only need to inset the SxS, open the SONY Transfer application, select the clips that you want and hit “Import”.
The re-wrapping just change the “packing” of the file without changing the picture/audio information. No generation lost.
In few minutes you get all your footage in your HD as .mov. ready to edit. The workflow can not be easier.
I’m really happy about the EX-1 and I really recommend a try.
Cheers,

Ok. So I guess the step you are leaving out is the archiving step. In other words, in my scenario, you are skipping step one. In a situation where I’ll be using cards and downloading them onto a hard drive and immediately using the cards again, I’ll want 2 copies of the files. It seems that a lot of people in the P2 world first make a copy of the contents of the card onto one HD. Then they “transfer” the video clips onto their scratch disk.
It seems in your case, you’re doing the steps in the opposite order. First your “transferring” the video clips onto a scratch disk, and then at some later time, making a backup of the clips. And I suppose if you have a RAID 1 or something, you would have to make the copy, since the RAID would be doing that for you. And really, this scenario works for P2 or SxS.
Thanks for your feedback. It only makes my decision harder.

Hi Trevor,
You can do both things and in the order that you want.
You can just drag and drop the full contents of the SxS card to your HD or download/convert that to QT.
Both cases the process takes just few minutes.
To keep the SxS files makes sense if you want to keep the files metadata. I don’t care about that so normally I just convert and back up as .mov.

[Trevor Ward] “Thanks for your feedback. It only makes my decision harder.”
if your decision is between P2 and XDCAM, the XDCAM workflow is easier and faster. About the quality you have to compare the pictures from the two cameras that you are comparing.
i made my decision long ago. I was about to buy a HVX-200 two tears ago when I heard to talk about the EX-1.
First I wasn’t much convinced because the MPEG-2 format. When I started to see pictures from the camera I made my mind. Now I’m really happy that I was patience enough to wait for the EX-1.

Sorry but this is not a correct statement.
The SxS format is encoded in an MPEG 2 format according,
for whom I consult under contract on this camera system.gary adcock

Your are absolutely right Gary.
They are MPEG-2 wrapped as MP4.
When imported are re-wrapped as QT or MFX.
BTW, very interesting your article about ProRess.
I read a thread were you pointed out many important facts about Proress.
I sow it last week while I was traveling so I couldn’t ask you few things.
I’ll give it a read again.

Sony did us all a disservice by not using standardized naming on their internal file structures.
and thanks for the comments on my article, I just started the second phase of testing to include all of the current 10bit codecs this time including Cineform, AVCi and Sheer.

[gary adcock] ” I just started the second phase of testing to include all of the current 10bit codecs this time including Cineform, AVCi and Sheer. “
i think this will be very interesting. Since Marco Solorio made his comparative study five years ago I haven’t see any other serious test.
I trying to make a more modest test comparing the results when up/downscaling in FC, Compressor and with the ioHD.
The problem I have is that i can only feed the ioHD with the EX-1 and with my DVCam.
So far I’ve compared Compressor and FC.
For up-sizing Compressor clearly beats FC. But for downscaling the difference is not that clear and FC works much faster.
Lets see what happens with the AJA.
Cheers,
