Well, you don't need Linux for that: http://support.microsoft.com/kb/69575 I'll have to give it a try.

For the new users such as myself who do not see "spanning" in FAQ. I read the above posts. I have my GH2 on stock settings. Question is, are you saying that the goal with each hack is you want it to span? Is spanning a good thing? The stock settings don't span correct? What I'm asking is, if I upgrade my camera to another hack (still haven't decided which), will that be part of the sacrifice, that now 4gb files will be created as opposed to one continuous stream? Sorry I don't completely understand what is good or bad and which hack to use. I have one lens: 14-140 and one card (so far) - class 10 transcend 32gb, -which hack to get and is it worth doing before I get more cards and more lenses?

Try Slipstream v1 (Rev B) for reliability and spanning in all modes plus iA.

Driftwood Cluster X Series 'Slipstream #1 (Rev B)

72Mbps max IPB frame 1080p24 PLUS 68Mbps max IPB frame FSH/HBR/720p modes

All settings SPAN (SH/FSH/H) according to my tests (Ive had spanning on 720p60SH at 5 files with a datarate at 50Mbps). This is a great setting which appears to pass spanning, iA modes and death charts in all REC modes. Its a mix of 'Nebula' meets 'DREWnet' and is the first in a series of combi settings that attempts to offer decent IQ together with perfect timing and good bitrates to accomodate spanning.

Give it a try and let me know how you get on. See page 1 for details about these new settings & to download Slipstream #1 (Rev B).

All rec modes tested on a Sandisk 45MBPS SD card. 14-140mm sharp lens used in test.

My Patriot EP 64gb spans very well and makes the file transfer part fast as well. But I don't run the highest bitrates in shows where I need to span. I'm using Drew set to 60 right now and Flowmotion on the Lsetting. The one and only one time I was able to crash FM on the hedge of doom it saved the end of the file as well. In live shows, I always have some Camcorders running. SD cards are not 100 percent reliable, and there is nothing worse than having to tell a client that the event was not recorded.

I'll try the Slipstream soon but right now I'm patched out.

I shot about 20 minutes with CBrandin 44M/32M at 24L spanning setting which made two clips on my Sandisk 16gb 30MBPS class 10 card. Using PPro CS 6 on Windows 7, in the second clip, the audio seems to span fine. On the video side, on the second clip the first three frames are the same so by the forth frame there is a slight "jump cut". Can anyone tell me what I can expect with spanning GH2 hacks and if there is any way to fix this?

@arvidtp So using Sanity 5.1, you don't get the glitche between two spanning files anymore so you no need to convert them to one file?

Since CBrandin 44M/32M is a spanning hack, I thought there wouldn't be any problems with the lower bit rate. If you successfully merge the two files, would that mean the frames are there "hidden" and by merging it's brought out? When I played the second file frame by frame, the reproduction is there and I wonder if merging would reveal the invisible frames.

@tinyrobot no - I should have been more clear. I don't get the glitches anymore only because I no longer use that method of importing. I just use final cut pro X now. @balazer is right - hacks don't change how spanned files are written, except that some make it just plain fail.

I recently shot a TEDx event on Cake 2.3 (chosen for it's spanning reliability). It was a multi cam shoot (4 cams), with the cameras on all day for over 9 hours (using AC power). Not a SINGLE failure. Granted, I did use the SanDisk SD card formatter and formatted all the cards 3 times each with that software beforehand, then 2 times each in camera, which certainly helped keep the cards at their healthiest. Editing in Premiere Pro CS 5.5 has been a breeze, only have to drag the first file of the span onto the timeline.

For non-event stuff, I've been really enjoying Moon Trial 5, but for spanning reliability I can confidently recommend Cake 2.3

I've not used Quantum Rocket, but sometimes with Sanity or Sanity X my spanned clips don't show up in FCPX's import. Not sure why this happens sometimes and not other times. You can get the clips out manually. If you're using OSX 10.8 or greater by right-clicking the AVCHD "file" (its actually a folder but the OS is annoyingly showing it as a package, trying to keep novice users from screwing things up) and choosing "Show Contents" like you would on a app package. Then so the same for BDMV and STREAM folders. If using an earlier OS X, they should just be folders.

Then take the .MTS files out and open them with quicktime X and save them as quicktime movies. You could try to use terminal to cat (concatenate) the .MTS files together first to get one continuous movie, but i find usually the resulting concatenated file fails to play properly in this situation (which is maybe why the software was failing to import the clip in the first place).

PS - Nothing about the hardware of your computer would influence this, just the software you have installed (unless of course the hardware is too old to run the new software you want). However, you will find a huge jump in performance for HD video editing between a 2008 macbook and a 2014, or even 2011 one (I have/use an early 2008, a late 2011 and a mid 2014 macbook and the later two are way way faster for video)
