CF-Cards fast enough for 1920x1080p24/25 5D3 MLraw video

[weoul]

After 2 warming runs (about 20 sec) I get  85-86MB/S using 128Gb Transcend 1000x CF card - contunius shooting 1920X1080 25p, Global Draw on (excluding zebras) with hystogram and focus peak on

For   64GB model it is enough 1 warming until it works perfectly. About 3MB/s speedy of her more capacious sister.

May be this info will help to smbody.

That is very useful to me. You are getting numbers from 5 minute benchmark?
Is your camera very new or more than 6 months old?
Thanks for the details! Maybe a few more will share.
I will try 25fp

Isn't there any CF card can record 1920*1080 30fps

It must be as fast as 107MB/s write speed.

KomputerBay 64 gig 1000x SM2236AC

Around 950 frames with 1920x1080 @ 30 fps, continuous with hacked preview.  This is with the June 28th build, I'm very impressed.  On the builds from earlier this month I would only see around 300-500 frames and around 1000 with the hacked preview.  The card itself has a 95 MB/s write and 120 MB/s read speed.

Benchmarks show silly low numbers - 75-78MB/s at max Buffer size.
At the same time I usually get this:



I real situation shooting 1 min is enough for me.

Camera is rather old , I bought it september last year.

I use a Sandisk Extreme Pro CF 16GB specified to 90MB/s. I can record 1920x1080 25fps. Only tried up to 15 seconds or so but no dropped frames afaik.

I also managed to record 1s to a SD card, Sandisk Extreme Pro 45MB/s. I assume the buffer fills up and then it's stop while pictures are shipped to the card.

Just wanted to put it out there that we bought eight 64GB Komputerbay CF cards and they all do great recording 1920x1080/24P RAW on the 5D Mark III. I did very long takes. Sometimes it was one take that filled up the card (about 12 minutes). We had no issues.

It was also cool that I could download the cards faster than it took to record a whole card. The setup was a four port eSATA card in a thunderbolt enclosure. I used two RED CF card readers with eSATA and wrote to two OWC two-drive RAIDs. I'm sure there's a more cost efficient solution out there, but with this set up I was able to shoot RAW with two cameras in an interview setting and I was never in danger of filling up the cards.

This is really fun! Thank ML community!!!

5 minute test with komputerbay 64gb 1000x
is this the speed everyone else getting or does anyone have faster speeds?

I have a Transcend 1000x 64GB card and I managed to record continuously in 1920x1080 30 fps!!! I used the hacked preview mode and  global draw off. Wow!!

[Mickeyboo]

My two Transcend 1000x 64GB cards have worked flawlessly at 24fps 1920x1080, no dropped frames with global draw off on
5d Mark 3.

[jojo]

30 fps 1920x1080! Proof!

what card?

what card?

Transcend 1000x 64 GB straight out of the package!

[aaphotog]

I think there are other variables besides cf card itself. Maybe build / chipset batch for 5dmk3 itself?
I just received 2 Lexmark 64GB 1000x and they are performing almost identically to the two transcend 64GB 1000x.
Highly unlikely. When I complained to reseller about transcend (which I was exchanging for lexar plus $) one of their canon reps said 5dmk3 cn only write a 76GBps max (but with Alex DMA code obviously number is different). But maybe cards are not actually bottleneck but rather build of 5dmk3.

So my 5dmk3 is like 9 months old. Are the people who have same transcend and lexar cards as me working using brand new or 6-9 month old version?
And komputerbay seems to have highest luck but I really don't feel like rolling the dice a third time!

I asked for people to share actual read write rates by card and now also by camera age / serial
Wonder if Alex can try benchmark with higher buffer size replacing the small (and why so many small tests?) sizes with larger buffers - or is 16384K largest possible?

And does crop mode write faster or same? What row length / formats could I get that require less write speed? 2k by some funky length at 24fps is better than no continuous recording!
And is 25fps faster or slower than 24 (you never know). For transcend formatting to exfat had no benefit.

Otherwise it is useless even though it has great potential.
                    W/R MBps for buffer:       2k         3k         4k          16k        32k(other test)
Transcend 64GB 1000x CF #1         56/83    65/93     65/93    81/119      80/
                                       #2         Similar I deleted the .bmp                 78/
Lexmark   64GB 1000x CF #1          35/44    41/44    42/56     79/104
                                       #2.         36/45    42/43    43/57     81/107

Anyway the values for 16k writes are too similar to be limited just by the cards across vendors - it looks like something on the camera / code side.
Please provide any relevant data you have.
And I have asked 5 ways in 5 forums with no answers:
What are ideal settings after reset to defaults for 5dmk3 raw performance.
I have tried most related settings / tweaks (no draw, slow write flag, etc) but don't see any change in write at 16k.
And I have also asked for confirmation that raw recording uses 16k buffer and that other sizes (larger)  not improve chance of working.
Sigh

Try another card. Maybe he lied to you. It's either that, or he doesn't know how and what you're doing with your 5d3.

I got 1920x1152 (24p) with my Transcend 128GB 1000x card too after a little warm up.

[aspire.saadi]

Has anyone tried lexar 800 x cards ?

[eyeland]

Has anyone tried lexar 800 x cards ?

I didn't benchmark it in-camera yet, but in crystalmark the Lexar 800x comes in very close to my Transcend 400x @ 40mb/s

Komputer Bay 1050X 128GB  I just ran 24 FPS  1920x1080 for a continuious 128.3 GB without a dropped frame, June 28 build, 5D Mark 3 global drawing off. This is a new card just released not to be confused with the previous 1000X 128 GB.

What about 25fps?

[grooveminister]

30 fps 1920x1080! Proof!

What build?

[grooveminister]

In the meantime I´ve orderer a Transcend 64GB 1000x card as well, but it doesn´t perform significantly better than the 128 GB version.
1080p30 is impossible with the card - but it seems to achieve a constant write speed of around 90 MB/s - so it´s a bit safer to record 1080p25 compared to the 128 GB version.

[Mido]

I can confirm that I'm getting 99-100MB/s with Transcend 64GB 1000x. Best card so far. June 27th build.

Are you still happy with the KomputerBay 128 GB x1050 for 1920x1080 25P RAW on the 5D III ?
Anyone else tried this card?
Thanks!

Hello,

I just ask for a little help to buy a memory card. I hesitate between the Lexar 1000x 32GB and the TRANSCEND 1000x 32GB. I said that the TRANSCEND is a little cheaper. So what card between the two?

I film on the 5D mark 2
