Clip Browser: is it necessary?

Bruce Rawlings · April 19th, 2009, 06:12 AM

I have sat down quietly this weekend and "cracked" Clip Browser having not succeeded in the past. I cannot now contemplate transferring files without CRC. As Craig says it only takes one incident and that may well be one too many. For me, now that I have the workflow sorted there will be no other way of working.

Wow, this is a scary thought but I've been using the EX1 since early 2008 and I have never heard of CRC before. The scary thing is that I have been working on a long term project where we have a couple of TB in EX1 footage that are transferred and backed up to second drives but we haven't started editing it yet I surely hope we won't encounter the same problems as Peter Mee. I have always just marked all clips and dragged them into the second explore window in clip browser which was opened to the folder I wanted the clips to goß is there anything wrong with this method, if CRC is checked? I like that method because sometimes I copy individual clips to folders already containing other clips if they belong to the same sequence. Although in the very beginning I used to just copy the BPAV to where I wanted suing windows explore without clip browser and I would think this method is not recommended at all?
I just checked my clip browser settings and CRC was not checked and "priority in move" was set to "processing speed". I have now checked "data protection" in "priority in move" and also checked CRC. But under the CRC option there's a window with a path which says "copy all files to:" and I'm not sure what it means? What files? Your clips destination is chosen by you at the moment you copy right?
Also what is little code in the window clip ID?

Hi Michael.
I didn´t use to use the CB and just dragged and dropped the BPVAs and never had a problem. Then reading about the CB here and it´s benefits made me start to use it.

I just want to try to comfort you and say that it´s highly unlikely that you have problems with your footage, but use CB from now for the added peace of mind.

Applause, Kudos, (select accolade of your choice and place here)!
That's exactly the point. CRC is a seat belt. It protects you against the rare (but catastrophic) accident.

The CRC or Cyclic Redundancy Check has been around in one form or another since the early 1960's. Simply stated it is an error detecting code. There are a number of CRC standards. You can read more about it in Wikipedia.

I've been wondering about this. I used Log and Transfer almost exclusively with my old HVX and noticed you could use it with SxS media as well.

I take it from reading through this that Log and Transfer does not perform any sort of CRC when importing?

If this is the case - I'm wondering what the benefit of using Log and Transfer is vs. CB?

CB good for backing up. Log and Transfer good for importing. Two VERY DIFFERENT functions.

Kellen Dengler · April 20th, 2009, 12:37 PM

So you mean like backing up to multiple locations?

I understand that CB will allow you to do that. I guess what I don't get is - if you use Log and Transfer to import your clips, they are stored into your specified Capture Scratch folder. Couldn't you just back those clips up else where later to achieve the same thing CB does?

I've been using Clip Browser, but I'm just wondering what it does differently than Log and Transfer?

Craig Seeman · April 20th, 2009, 01:38 PM

CB copies and does CRC check to make sure the copy is good. That has nothing to do with Log and Transfer at all.

You need to back up your camera masters which are the BPAV folders.

What you import is rewrapped as .mov which may be very difficult to port to another non FCP system unlike the camera masters.

Kellen Dengler · April 20th, 2009, 02:01 PM

Yeah I mean typically I use CB initially and then set up my clips into FCP when I'm ready to begin my project. I just tried the Log and Transfer just to see what was left in the folder besides the clips and you are right - no BPAV folders.

I guess I didn't really realize that the clips imported via Log and Transfer are FCP compatible only. That's really good to know for future reference. Thanks!
