5D Mark II Freezes / Locks up / Buffer Problem SOLVED

Thanks Storm for your help. Really appreciated.
Now the latest update. I have called Canon support and described the problem I m facing with my Extreme III 32 GB Compact Flash, and the advice they gave me is to try another card. I have asked them which vendor do you recomend, as expected they didn't provide any preferance and they mentioned that all card vendors should work. My last question was, should I try a smaller size card (instead of the 32 GB) the answer was straight NO, this is one of the latest models they have (5d Mark II) and it supports this amount of storage. The person told me that 90% the problem is in the card and not the camera body. This made my life easier, but didn't solve anything.
After that I saw your post, so I decided to buy a Lexar CF 300 X card 16GB. Tried to use it and test it during the last 2 days, all worked fine till this moment. :-)
So my last step was to call SanDisk support in order to report the problem and ask them how they can help. I m now quite confident that the problem is not in my Camera. So after giving all the needed information, the support guy told me that Extrem III 32 GB are not supported on Canon 5D Mark II camera!!!!! He even refered to Sandisk website to illustrate that. IT was shocking for me to receive two different information about the card compitability from both companies.
Regardless who is correct and who is wrong. My aim at the end is to have a workable solution, and this is definetly is not with ExtremeIII cards. I really do not want to waste more money and try Extreme IV :-)
Thanks all for your help.

(Tested using Firmware 1.0.7 and a brand new Sandisk Extreme III 16GB)
Greetings from Helsinki.
 
i get the freeze issue, but it only happens the first time you record to the card, after booting Magic Lantern. Using 2x 32GIG Sandisk ExtremeIII 30MB/sec cards. The lockup isnt permanent, it just needs 3-4 seconds to stabilize then its fine. Usually as soon as i load ML, i just record for 10 seconds, clear the problem then its fine...
 
I still got the same problem under firmware 2.0.3
I am shooting on a SanDisk Extreme III 4 GB. Short films have been saved to the CF card even though the camera freezed and I had to pull the Battery.
Do I have to buy CF cards from a different brand to be "safer"?
Thanks for your help

Same problem - freezing in movie mode

Same problem - freezing in movie mode

I read this thread and describes the same problem I have always had with the Canon 5D MkII - it randomly freezes in movie mode (bars appear on the screen) and I have to take out the battery to reset the camera. This means whatever I recorded is lost.

The bottom line is that I don't trust the camera. I shoot a lot with it and I'd say about 10% of the sequences I film lock up. If I'm interviewing someone, it's incredibly embarrassing.

I've tried multiple cards. It still happens. This is a problem with the camera.

Has anyone got another solution please? Otherwise, this thing is going on ebay.

As many 5D2s as there are out there, if it was a problem with more than just a couple, I would think we'd hear about it. I think you've got a lemon. Talk to Canon about it.
 
As a follow up, I called Canon (thanks for prompting me) and they said I had to use a UDMA card. I was using a Sandisk Extreme III 30mps card (both 8gb and 4gb) -- so it seems I now have the answer to why some movies were freezing. Maybe I'm the person who didn't realize this subtle difference in the type of cards needed (I'm no pro), but I thought I'd share this here just in case someone else has the same problem.

Great message board.

Ok, I have to apologize for jumping in without having my feet wet (or whatever the right saying is LOL)

When I saw your post the other day, I didn't see the whole thread and I should have gone back to read the whole thing.

I think you're being bitten by the 'bit rate' of the cards. Especially if you're using the latest Canon firmware on the 5D2 - 2.0.7

The original specs on the 5D2 as quoted earlier in this thread stated that the output of the video going down the pipe to your card was pretty low and that 30mb/s cards were more than enough.

However, the latest firmware bumped up that bit rate to 45mb/s if I remember correctly. Therefore slower cards could indeed cause problems... tho most times, I've just heard of the data not getting written - as opposed to the camera locking up.

So, now Canon is definitely recommending the UMDA cards as I think most of them are rated at 60mb/s

Sorry I didn't read the whole thing.
 
I also have this happen yesterday.
I am using "Team 600X UDMA 16 GB compact flash".and have never experience freeze before until yesterday.

Before yesterday(the freezing happen), I was taking out my card and transfering files to a pc. After that I delete the *.THM files from the card without deleting the *.Mov files.
And return the card to the 5d again.When I browse the card from camera,it did not show any video files,instead just the image files(the video files stil there).
And then I record a video,after a few second the video start to freeze,the red led indicator lit up and won't blink.buffer bar in live view. After about 1-2 minute freezing,it return to normal again.And the video I was recording is there but stop until the time it got freeze.

I try to record video again several times,and everything goes normal.

Than I just delete the video that created by the freeze up moment. And when I hit record,the freeze problem happen again.
mmmm....something wrong.I am guessing there are some problem about file management,not the card.

Because, After I formated the card,I never had that happen again,until today.

has anyone,experience this too?or anyone try it?
