I have been doing some test with small changes & new inis using a sandisk 32Gb 95mb and is it constant 280 frames at 1792x752 and one time recording with crop factor 295frames, so I think it is pretty much the same as the others, doesnt make much of a difference between the 45mb and the 95mb sd cards.

Have to do something w/ the 23.976.. its calculated wrong and doesn't give normal timings with high shutter.

I googled it. What it is is that when film gets put on television or something of this sort, the sound is pushed off. With 23.976 the audio is in sync.

Overriding 23.967 over 30P is supposed to give 1/3000 or at least 2000 shutter. It does on other cameras.

Whats the best cluster size to use on these sd cards? Right now I'm using 4096.

How about the maximum size allowed for 6D SD cards ,128GB could be a good solution for recording raw ?
Anyone tried in decent conditions 128GB (Transcend , Komputerbay ,etc) ?
thanks,

It appears that the final conclusion is that the Sandisk Extreme 45MB/s SD card is the fastest for the Canon 6D ... correct?

Best choice is the 45mb/s. It ties with other faster cards because the camera is hardware limited.

Good news!!! There's a new line of high speed SD cards from Toshiba. Here's the press release:

And its not going to have any improvement over the sandisk extreme because the camera is limited to only 41 mb/s.

How about Toshiba Exceria Type 1, I heard it has a 90mb write speed, did someone test that cards?

kgv5

There is a hardware limit, slow SD drive controller. Card speed above 40-41 MB/s doesn't matter.

Newbie question...

I presume the above goes for shooting RAW video on the 6D too - not just photos?

I have 4x Scandisk Extreme 32GB 45MB/s cards and was wondering if I needed to upgrade to some very pricey ($119 each) ScanDisk Extreme  Pro 64GB SDXC 90MB/s cards.  Based on my reading of this thread the Extreme Pro 90MB/s cards often no/minimal performance benefit - their speed being limited by 6D hardware restrictions (max speed achievable 40-41 MB/s).

Thanks to kgv5 and other posters for saving me $$$$$

xNiNELiVES

Yes of course, these write speeds go for everything.

I use ScanDisk Extreme  Pro 32GB 95MB/s cards and get ~2600 frames (~01m:40s) 1664x640, 40.1 MB/s. Card format exFat with 64k cluster. Build DualIso-FullPack (2013-08-11). Hack ON, extra hack ON. But enable buffer to 255 failed, it remained 151 (( Can something not so doing. With 255, it will surely be even better result.

kaktus

Changing the settings, exposing the "raw" or "jpeg", to photo mode turned out that it also affects the length of recording video in raw. In a previous post I wrote that managed to get about 2600 frames. In the case was put on the "jpeg". Setting the "raw" I got a recording duration in the 5800 frames, or 04m:02s to fill the buffer and auto stop recording.

And, accordingly, the file size is about 5 GB. And raw2dng unpacks only those that up to 4 Gigabytes.  :'( :'( :'( Or is there another raw2dng, which unpacks large files?

Use exfat or combine the R00 files with the raw.

Not very understand you. I only month as ML use, not all yet understand.

To activate 255 buffer:

turn cam off
switch to stills mode
turn on cam
turn on LV
go to canon menu
go to fourth tab
long exp. NR - OFF
high ISO speed NR - NR (multi)
turn on ML menu
third tab from the right
go down to free memory
check - should be 255MB

remember, that first recording always is shorter somehow, so press record button, let the camera to record couple of frames, press record off.
Now you are ready for full 255MB buffer recording.
So let us know how many frames do you have with resolutions from my previous posts, thanks  :)

                   
I have not been managed to activate it in this way. (( How to do this more?

Set quality to raw, use the memory hack in Movie mode, it will auto enable 255 when it starts up by going in and out of LV. You should see "busy" on the screen sometimes, make sure this feature is on in the module.

xNiNELiVES, could you please check especially 1792x752 with working LV and force left? I have 280 frames, speed 41 for a half second, than dropping to 39-39,5. This res is very nice, 2,39:1, 107,5% upscale and quite usable 10-12 seconds of footage. I wonder if you could get some more frames with sandisk 95.

I've been testing out the 6D port (from this post) using my SanDisk 45MB/s Extreme card and can only seem to get around 100-140 frames.

Can I ask what your exact setup is to achieve 280 frames at 1792x752? Would be great to get results like that.

jayb

Tried again today, can only get 40 frames at 1792 now. Weird.

Are you sure you've got an authentic Sandisk card? Esp. with this brand there's said to be a very high percentage of fakes which have slower write speed... you should try to do a card benchmark on a fast usb interface to see what your card is capable of at all.

Yeah my cards are authentic. I didn't have the image quality set to RAW (doh) setting that that got me back to around 140 frames. Any idea how to get more?

This is what I do to setup (using all the ML defaults untouched to start):

• SET IMAGE QUALITY TO RAW
• TURN ON ML MODULES
• SET RAW VIDEO TO 1792x752
• TURN ON VIDEO MODE

- Card warm-up: OFF
- Memory hack : ON
- Extra Hacks : ON

malloc 445k
AllocateMemory 1536k
stack space 529k
shoot_malloc contig 32M
shoot_malloc total 151M

Jayb, I think the files you are using from the post you are mentioning are from the 28th of august, it maybe that the build is very old. Try using a newer build:
