@vtablix I am afraid that it does not sound like your card can take advantage of the increased bitrate for any of the hacks. Sanity 5 is only 36 mbps and sometimes the files are even smaller than un-hacked settings.

Honestly, I have not even tried class 4 cards during my testing and my guess is that the Class 4 cards that were tested were from the higher performance brands.

But, before we give up on this completely, what mode and framerate/resolution were you shooting? The 24L mode will work at lower bitrates than 24H. Keeping the lens in manual focus will keep the camera from working too hard, and the same goes for making sure that iDynamic and IR are disabled. Also, shooting without ETC is more stable than shooting with ETC mode engaged. And just like 24L uses less than 24H, keep that for other framerates "H" uses less than "SH" and "FH" less than "FSH".

But if you want to use the hacked settings more fully, you really should get at least at Transcend Class 10 card.

@vtablix Keep in mind, a class 4 card is supposed to have a minimum write speed of 4MB/s (so only 32mbps). It makes sense that it would have trouble with even Sanity 5 (38mbps).

As far as cards, a class 10 Transcend card is rated for at least 10MB/s minimum write speed (80mbps) so you could run several of the moderate hacks just fine.

A SanDisk 30MB/s, 45MB/s or 95MB/s or a Delkin 633x (with a 95MB/s read speed and a write speed of at least 80MB/s) would be my suggestion for anything more demanding than that.

And remember that if you want longer record times, you also do not want your bitrate to go too high. Try FlowMotion 2.02, Cluster 6, Sanity 5, Natural or No Adverse Effects.

Here is a less expensive cards from the same site (also SanDisk, shipped by Amazon) that should do well with settings designed for longer record times. I would try that one first and only get a more expensive one if you need it.

http://www.amazon.co.uk/Sandisk-32GB-Extreme-Video-Memory/dp/B00428N88M/ref=sr_1_38?s=computers&ie=UTF8&qid=1347404022&sr=1-38

I am guessing you are in the U.K. from your mention of prices, so I would mention that some of the settings are much better for 25P HBR than others. Back before Driftwood released Canis Majoris, I had a chance to test a lot of settings on SanDisk 95MB/s 64GB, Delkin 95MB/s 16GB and a Transcend Class 10 64GB. In 25P HBR mode, many Driftwood settings had difficulty, even with the SanDisk 95MB/s 64GB.

Sedna AQ1 A, Sedna Q20 A and Mysteron all worked properly but did not span in 25P HBR on that high-end card. FlowMotion 2.02 spanned in a wider variety of modes on a wider variety of cards.

Also, you can get a rough idea of the card overall performance (not GH2 specific) by finding it in Rob Galbraith's database. http://www.robgalbraith.com/bins/multi_page.asp?cid=6007

@vtablix SanDisk tended to make products that exceeded the specifications of a given class. They have class 6 cards that go way beyond class 6 and class 10 cards that go way beyond class 10 bandwidth, etc. Also, some of their high-performance cards were released before the class 10 designation started being used (so you had "class 6" cards that were way faster than competitors class 10 ones).

But what I have not encountered is a legitimate SanDisk card that peformed below the class rating.

For compactflash cards, if a SanDisk and Transcend card had the same speed rating (and mind you, the speed ratings are more consistently specific for CF cards) then the Transcend performance tended to be 80 to 85% of a similarly rated SanDisk card. In the U.S., that means you are typically getting >80% of the performance for 50 to 60% of the price, so they are a good value.

It is not that the speed ratings do not matter, it is that different brands treat them differently. SanDisk is one of the most stringent in their ratings.

Honestly, due to how much is changing with the GH2 hacked settings (and how frequently) it is no surprise that is difficult to be sure whether a given card will work with a given setting, etc.

But the good news about the most expensive card I mentioned (the SanDisk 64GB 95MB/s) is that it is not just one of the highest performing ones, it is also very frequently tested.

Anyway, Transcend, Delkin or SanDisk - possibly Lexar. But I would not mess with other brands at the moment because there simply is not enough testing data to make good suggestions.

Out of in the moment necessity I picked up 2 Silicon Power 16gb class 10 cards, for the lovely price of 1100 yen each (about $13 USD). On L mode using Sedna A max detail their were zero issues. In H mode it seemed to crash around 30 seconds in, but that is 20 seconds longer than my other lower end card. Maybe with some gentle persuasion the SP card may not crash. Either way top version of the top hack, so I suspect these cards will perform very well on most other hacks. These are last years cards too, hence the price. I am very impressed, and the price can't be beat.

sandisk 45mb/s 32gb are cheap here for under 30 euros. they give me no problems with driftwoods quantum 9b - streamparser showing 118 mbit/s :)

hello everyone, hello @thepalalias

I wanna try FlowMotion v2 or Apocalypse Now. What kind of cards I have to buy ?

I need to record long interviews (+ 1 hour) and outdoor shootings. 1024/24

Actually, I'm lost. I really don't know what to choose. Do I need 45 MB/s or 95 MB/s ? How many minutes can I shoot with a 32 GB and with 64 GB ?

Also, I'm planning to try the GH3...

Thank you so much.

update on silicon power 16gb class 10 cards. The price on these dropped to 980yen locally, and I have tested with CM Night, and some of Driftwoods newest patches, and this card works flawlessly in all modes. They have a couple 32GB cards at the shop for 2400yen I am tempted to snatch up, but it seems all cards are dropping in price right now, so I may wait a bit.
