not to derail, but you should try out sanity 5 for events - been using that exclusively for a few months now and spanning has been rock solid for me as long as i follow Ralph's guidelines (which are not that restrictive).

@Daniel_R For extended-duration takes with 4GB file-spanning, try Flow Motion's 60Mbps video modes: 24L @1080p, FH @ 1080i, and H @ 720p. These modes will span reliably on Class 10 cards rated 30MB/sec and higher. The 60Mbps modes work exactly the same as their 100Mbps counterparts, delivering excellent quality with just a notch more compression.

Cake has spanned 100% reliably in my experience, and I don't recall anyone reporting a spanning failure on P-V. There are no restrictions on which lenses or camera settings you can use: Lumix lenses, high ISOs, and ETC mode are fine. The choice of memory card does matter for spanning. I designed Cake for SanDisk Extreme cards, though many people have used other Class 10 cards with success. The SanDisk 32-GB 95 MB/s card is the best choice. Performing several full overwrite formattings with the SD Card Association Formatter utility will put your card in better shape. 24L is a slightly lower bit rate than 24H. I think you'll find that Cake easily beats Sanity for quality, especially for low light and high noise, and comes very very close to the highest bit rate hacks.

Encoder settings have no impact on the magnitude of the rolling shutter effect. Rolling shutter is a function solely of which mode you have selected and the ETC setting. 720p has less rolling shutter than 1080p, and ETC has less than with ETC off. You'll find a table of the GH2's video modes in the FAQ: http://www.personal-view.com/faqs/gh2-usage/gh2-usage

Will try that at a later date Lee. Thanks very much :)

@Balazer I don't exactly know what this issue is. Rolling shutter has never EVER been this noticeable on my GH2. Unless I'm completely blind and it's been there the whole time... but I would have noticed it. A lot of my tests were handheld, so rolling shutter is no doubt worse in handheld... but it's not been this bad before. This is a bit worrying for me as I shoot on a shoulder rig for many of my gigs. But, I'll find a workaround. The worst of the rolling shutter is when I shoot HBR in PAL mode, using a manual lens (pentax 50mm 1.7) and Tele/ETC mode is OFF.

Appreciate all your answers.

I have tried to put a Youtube video here by embedding the code in the comment but the video doesn't show up..Can some body help me and tell me how to embed a Youtube video here...Thanks

no, then maybe this..

Yeeaaah!

@rikyxxx thanks!

one done with Cake 2.3 HBR 25p settings

@briangeorge Nice acoustic version of the "old" dance song L'amour toujours (I'll Fly with You) by Gigi D'Agostino. It reminds me when I was in my early 20s :-)

Great videos again.

@briangeorge Como lake? :)

@thomisus yes Como Lake indeed

@rikyxxx i'll try to avoid Gigi D'Agostino covers..;p Also think we are getting a little off topic...the great Cake hack!

Yep - agree. It's the one I use all the time. It just works.
