it doesn't matter if you use ducati editions* on 550D, it can handle only 20MB/s data output to the SD card, I'm using both Sandisk extreme 20MB/s & 30MB/s (old series) and new Sandisk extreme 45MB/s there is no difference on bitrate increase / decrease.

here is the test of Sandisk extreme 30 and 45MB/s at USB 3.0 card reader on my site.

*they are old, but if they were new, I know they can kick 120MB/s today.

Yeah I got a sandisk extreme 45 mb/s card and it's the same as my kingston class 10 card. Back it goes to costco.

I've got the same experience from my sandisk extreme 45 mb/s: i was disappointed, because it acts just slightly better then almost any other class 10 sd card, but then i got the sandisk extreme pro 95 mb/s, and now i'm easily getting stable 1152x464 for more than 600 frames at 23.976 fps.
It is just a strange “piece of luck” that sd controller bottleneck and write speed of 10 class sd cards are just about the same.
So you need a really fast card to be sure you hit the right one.

this is just funny you blame sandisk because of your slow cameras. I'm using 45MB/s card on EOS M, and 30MB/S on 550D without any problems.

here are other CLASS 10 cards, you can see the results!

they are not the same with sandisk extreme 45MB/s, even 30MB/s

toshiba class 10, white card, made in japan

sandisk ultra class 10, 30MB/s edition (which really sucks)
http://hepsicekiyor.wordpress.com/2013/05/13/sandisk-ultra-class-10-16gb-30mbs-testi/

transcend class 10, which surprised me a bit
http://hepsicekiyor.wordpress.com/2013/05/13/transcend-class-10-8gb-hafiza-karti-testi/

sandisk extreme cards has their own unique controllers and advanced write mechanisims, even sandisk usb drives uses trim option now.

Quick question... If I use FPS override I get the messed up colors instead of an image no matter how low I go with the FPS override. I turn the FPS override and I run this thing at full 24p at the same resolutions people have been lowering their FPS's to get without any frames dropping. I want to go higher but when I use the FPS override to help this is where I get the error

Ok Guys

I've shot some raw footage at 1152x656 @ 29.97. I have used raw2dng to get the dng files. I imported those files tp After Effects, made some minor changes, then saved as a premier pro project file.

Then I opened Premier, imported the project, then rendered the file out. When I look at the resulting video it just looks like a still and not video.

What am I missing here.

Any help would be greatly appreciated.

Because you already rendered it out, the only thing I can fathom is that the file has a huge bit rate and your computer can't handle it. In other words, it's "trying" to play the video but it's stuck on one frame. The funny thing I have noticed (and I now I can't remember if I downloaded a codec) is that I have the best luck playing the video with Windows Media Player of all things (if rendered out as a mov). Other than that....I have no idea! haha

Thanks for this, great numbers.

I get about 87 frames with 1280 at 3:1, 24fps with the sandisk extreme 45 mb/s and Kingston class10.

Anyone used this card? All the 5dm3 talk about komputerbay cards.

Your 550D can only write 20ishMB/sec to the card so no matter how good your card is the SD card controller won't be fast enough to use the card up to its full potential.

I'm running into an issue with raw2dng. It seems to work fine on a raw file 61 meg in size but when my raw file id 528 meg it does not work. Has anyone else experienced this??

Another build with the help of Xaint getting us a bit more memory for recording, I am getting much more frames before skipping now with 1280x432x24p 193 frames to be exact, was only getting 86 before his hack.

This also includes Alex's latest bitbuckit update, gives us more resolution choices looks like and a mem hack but doesnt seem to help our cam at all.

This includes Filemanager as will, you can find in the Debug menu.

Exactly  ! Then, download the modules (the very next download, just right under it) and follow instructions, so you can choose what build works better for your purpose (the "tragic lantern" or the "magic lantern" one)  8)

Get the latest build, I was only available to get 87 frames but with the last one I´m getting 197 frames 1280 3:1 resolution  ;)

I get 80 frames at 1152x460 with 23.976 fps with my Kingston sd card which is the same speed as the sandisk 45 mb/s.

You are getting like tens times the frames I am with the extreme pro.

Hey guys, sorry, I should of added this update a week ago, but this one is up to date even more, but the main thing is the ability to save RAW settings after restart.

Includes Magic and Tragic as well and Mem fix

Now I´m able to get 240 frames 3:1 1280x426 with magic raw, thanks mk11174!!!

Previous build gives me 300+ frames 1280x426 in photo mode at 23.976 fps (sandisk 95 mbps).
For me, this last update works slightly worse then previous. For example, i had 900+ frames 1152x460, but now its only about 600. And the previous one worked nicely in photo mode, giving me better results. The last one have some problems with photo mode.
The one great thing is the ability to save settings of the raw-rec modules for sure.

If you run the speed simulation script, you would notice that at 1152x460 you get 603 frames if the card write speed is 20.9 MB/s and 891 if the speed is 21.0. For reproducing the results: buffers 32x2+8, 23.976 fps, timing variation 0.

So these reports about slowdown are quite pointless.

I'm using the same card for every test (sandisk extreme pro 95 mbps 8gb) and with the latest build i get around 580 frames with 1152x460 at 23.976 fps, but with previous at least 900 and sometimes 1300. These results are consistent, not random. (magic raw)

Results for tragic raw:
with the previous build i have at least 386 frames at 1152x464
Now with these parameters recording stops everytime after 68 frames.

So obviously something is going on besides the card write speed etc.

So you have noticed a consistent slowdown of 0.1 MB/s? I don't think this is enough to jump to the conclusion that the latest build is any slower.

Well, for me 68 frames vs 386 is significant slow down indeed. In terms of real usability, but not the inner figures and values. Just facts for my setup (camera/card), no offence intended.
