Crazy re-write back to SXS card
on Jun 10, 2009 at 5:21:07 pm

I am attempting to write some files back to an SXS card. The clips currently reside in a Final Cut Pro (ver 6.0.5) project, and I am using the Export- Sony XDCam choice that pops up when I control-click the clip.

They were originally shot on an EX-1 and likely brought into the project using "Log and Transfer" when I was first learning what my workflow might be. However, I have doubt that the method of ingest should affect the export.

I have done this many times before with other projects, but today, I filled a card and upon checking the card with Clipbrowser I found only some of the clips appeared. I pulled the card from the reader and tried to "Restore Media?" in my EX-1, thinking that would help. It actually brought up a never-before-seen warning indicating "Media cannot be Restored".

I mounted the card back in my MacPro and opened the BPAV files and found that the clips I could not see, were being written as Quicktime files to the card unlike the other clips I could see, which were appearing as folders. Within those folders are 5 files ending in MP4, SMI, PPN, XML, and BIM.

The rougue files are seemingly random, appearing around other files which are written correctly. I can have one file write correctly, the next 2 that don't, the following 10 that again write correctly, and then the rest fail. Thier lengths vary between 10-30 seconds, and less than 3 minutes

When exporting, all appear to export the same. The Export window comes up with the settings as follows- Destination is the SXS card, Filename is the numerical value assigned by the camera and unchanged by me, Format is MP4(XDCAM EX), with intermediate files written to the /Volumes/Untitled, which is the SXS card.

As a test I deleted all the loose Quicktime files I could see within the BPAV and the camera could once again recognize the card and the correctly written files, yet trying to re-export the "bad" files yields the same results. They stubbornly write as Quicktimes.

I fear this has something to do with the latest OS updates I just downloaded. There have been other crazy thigs happening like one monitor not coming to life at boot-up, monitors having bad contrast after "waking up", and a few other wierd things.

I hope someone can help me figure this out.

Final cut Version 6.0.5, Mac OS X ver 10.5.7, 2 X 3 GHz Quad Core Intel Xeon, 6GB 800 MHz, DDR2 FB-DIMM, GSpeed 6TB Fibre Channel drive

A real mess Robert.
To write back from FC to an SxS card, the card must be formated but empty. Also there is a limit of 4GB that you can upload. This because the FAT32 formating.

Are you saying no clip larger than 4GB? Or 4BG is all you can ever write back to the card? I thought that was part of the Sony write-back software, to be able to bridge those 4GB barriers, and give you a seemless clip.

I have filled cards before, never with this much hassle. Of course the "Sony XDCAM HD & EX Workflows" manual had nothing- about a half a page on exporting from Final Cut.

The cards, I should have said, are the Sony SXS cards, 16GB. I reformatted the card I am using to see if that made a difference- It didn't. Nor did a re-start. Still working on it...

[Robert Semeniuk] "Are you saying no clip larger than 4GB? Or 4BG is all you can ever write back to the card?"
4 GBs in total Robert.
A 16 GBs card in camera get recorded in 4x4Gbs chops. Is the old story with all the FAT 32 HDs: No file bigger than 4GBs. FC or whatever reason can write only one 4 GB piece.
