Hei. Most of the hacks are capable of this. Some of the hacks that provides high bitrate will only work if you have high speed sd-cards like the Sandisk 95/64gb. Sanity is a good patch to start with, but do have a look around and ask questions in the various threads if you have specific questions about a patch.

As you've discovered, the ptool software lets you override the EU time limit and at the same time, you can use it to install the patches to get better quality video. Look at FAQ at the top of any page to get more info about ptool and as @haarvard says, search the threads for specific info on the different patches (just mentioning this for any other people who find this thread and are new to this).

Always make sure you read the ptool instructions, particularly abut using fully-charged, Panasonic batteries.

If you have installed a patch and your camera stops it is probably the card although sometimes certain lenses or camera settings can also cause recording to stop. Sanity and Cake are two good patches which work well on most cards with most lenses.

All patches are constantly being developed as you'll see if you read through the threads, but many of the patch authors put the latest versions of their patches on the first post. Check the whole of that patch's thread if in doubt that you have the latest versions.

Thanks @mark_the_Harp and @jpbturbo! I´ll get on this! :D

Do you simply tick the continuous motion picture only or you apply a certain patch?

My suggestion is: Check if your sd card is slow or faulty. It is recommended that you use class 10 card with minimum write speed of 30MB/second. Also check the capacity of the SD Card. If you capture video outdoor in bright sun and using wide angle lens, then there is a chance that your GH2 eats the card capacity very fast since it will capture more details compared to indoor scene. Good Luck!

It depends on your sd card's speed. But try flowmotion if no luck until now. it can record for hours.
