Clip Browser: is it necessary?

i've been using Clip Browser version 1 successfully for about a year now. i haven't had a need to upgrade to 2.5, but i did it anyways just to see the difference between the two. If you're only dumping/transferring footage from the SxS cards to a hard-drive, do you really need to use Sony Clip Browser? this leads me into my second question. on version 2.5 you have an option to use Data Protection and/or CRC. does anyone find these two functions to be necessary? i've read a few threads where people have had trouble transferring footage, but they weren't very specific. so, what are your thoughts?

thanks,
Mike

Regarding CRC, Are seat belts necessary?

Once accident and it can be crippling or fatal. In the course of lifetime one accident can cause you to lose the shoot, the client, maybe even your entire business.

Its very rare to have a problem with drag and drop. I don't know anyone who has experienced one. However I was finally convinced to switch to Clip Browser 2.5 and I don't see any reason not to use it. Its just as fast as drag and drop and frankly I loved the features it offered.

i've never had a problem with drag and drop. as long as your file system is structured properly there is very little chance of anything going wrong, but of course I always try to keep the cards intact until I can be 100% certain. Perhaps just something I learned from my photography business...

I'v read a few threads where people are beside themselves due to not using CB (with CRC checked on). Why go to the expense of XDCAM EX system and not follow through with Sony's strongest recommendation to safely copy the BPAV folder & files to other storage meduims using CB?

For me, it is a no brainer to use CB with CRC checked on. I do it as soon as possible after my recording and to 2 Lacie Rugged drives as well as 2 additional internal drives. I do another job in the meantime. Once checked, I then erase the sxs cards.

No fuss, no bother, mimimise/eliminate risk to possible corrupt files using the drag & drop method.

In terms of the newer versions of Clip Browser, don't forget the conversion tools that are built in. While I am still experimenting in terms of the overall conversion quality of Clip Browser vs alternate methods it seems reasonably good.

If you are using the SDHC cards and keeping them as archive, like tape, is there any reason you have to use the CRC & error detection? If you have the one in a thousand error on transfer, you can go back to the card to retransfer the clip.

When copying card-to-card in the camera, does the camera do this CRC & error detection?

To me, it's obvious that any mission-critical (i.e. paying gig, especially of a live action type) does call for every safety measure possible. For this kind of projects, I'm using either CB or ShotPut (both with CRC enabled).

For less critical tasks (like test shooting for PP tweaking, comparisons, etc.), I always want the clips to be ready on my HDD as quick as possible. In such situation, I don't even bother with copying entire BPAV's; I use Clip Browser's "Export MXF for NLE" straight from the SxS cards.

I wonder - if the CRC is set to ON in the CB's preferences, is it also in action when exporting (as opposed to copying)? Personally I doubt it, as exporting entire 8GB SxS card to mxf files takes seconds (no kidding - less than a minute) on my Quad desktop with PCIe ExpressCard reader...

Edit: after a second thought, I'm positive CRC is NOT active when re-wrapping; after all it would be comparing apples to oranges :)

My advice is ALWAYS use safe mode/CRC unless you are happy to lose footage.

I posted here a while back about an incident I had. Copied files from SxS using ClipBrowser with no safety. Everything looked fine and footage imported iinto FCP OK and I could edit. It was only when I tried to export from FCP that application errors started showing up and it transpired that I simply could not convert the footage in any way. Luckily I had not deleted the cards and re-transfered using safety/CRC and all was OK.

What was frightening was that it was at the END of the process that the problems manifested. Imagine if this had been a large projects with weeks or months between shoot and delivery? By that stage, cards would have been wiped.

Just a short question between: is the "data-proirity" and "CRC-check" from Tool-Options-menu active at any copying within clip-browser?

Especially:

- copying fresh shot clips from SDHC in USB-card reader to HDD?
- copying single clips from any drive / directory to another drive / directory?

Or is it just when using the "copy all" function when EX1 is connected via USB-cable to the pre-selected directory in Tool-Option-menu?

Last one is extreeeeeeeeeemly slow. One should invest in a real PC-Express-reader...

What about FCP Log & Transfer?

For non-critical projects I will often just use Log & Transfer from the card and then back up the QT files. Can these files "go bad"?

That is the exact question I have. You do a transfer from the SDHC card or SxS card that is only partially filled and use the "transfer all clips" of course the CRC will work if you have it checked.

What happens if you come back later and use the same SDHC card and only copy those clips that are new using the highlight/copy command or drag and drop to another folder - does the CRC work in that instance or only with "Copy All"

CRC works no matter if you're copying one or all your clips. Old or new, good or bad composition. hehehe

The average person might only get in to one car accident in a lifetime. Unfortunately lifetime ends at that moment.

If one reads this and other EX forums, the body count is certainly high enough.
