Ive made this vid with 650D with Satrianis Build from 04.07.2013.
It was only a bit of testing the RAW funcionality.

I can confirm spider's benchmark numbers.

If you have an USB 3.0 cardreader you can test your card with something like CrystalDiskMark (Windows only).
It is possible - sadly - that your card is a fake.

using this card http://www.amazon.com/SanDisk-Extreme-UHS-1-Memory-SDSDXP1-016G-X46/dp/B004JJN262

my card is fake isnt it ?

idont have USB 3.0 card reader. maybe i will check it latter another time

Doesn't look like 45 MByte/s to me ...
Just to be sure: You're using one of satriani's latest builds on 650D?

If you are about to purchase a USB 3.0 cardreader I can recommend Kingston FCR-HS3. Transfer speeds are very good with CF and SD. Mechanically it is not that convincing. The SD slot is not that well designed. Often the SD card is misaligned and gets stuck. If it happens, no harm is done to the card's and reader's contacts. And no reservations with CF slot.
Buying an USB 3.0 device makes not much sense if your computer only runs USB 2.0. You may need an additional USB 3.0 interface card then.

What are your settings? Maybe you have something enabled that eats the speed?
Try to set the mode dial to 'M' and leave the LiveView. Also, disable Global Draw before you run the benchmark.
It's worth a try - if you haven't used these settings for your benchmark yet - But I guess that won't help much.

Actually your benchmark looks like your card or your camera doesn't support UHS-I. Your card might be fake. Or your camera

Btw: I have a question. 1% mentioned that the EOS M and the 650D/700D probably all have the same issue: The recorded raw image is squished and has to be streched vertically in post. That happens on the 600D if you record in the 720p mode. But is it true that it can't be avoided on the 650D/700D? Or is it only an issue with the EOS M?

spider · « **Reply #105 on:** July 09, 2013, 05:23:04 PM »

How strong is it squished? I havent seen it on my videos from 650D.

elmatambre · « **Reply #106 on:** July 09, 2013, 06:19:56 PM »

i have problems too with the same card my card is original and new from extreme pro 16 gb 45mbs... but i read now this topic to understand what is my wrong settings in the camera or not...

Aborgh · « **Reply #107 on:** July 09, 2013, 06:21:08 PM »

Regarding the writing speed on 650D. Is it possible to overclock the controller that writes to the sd card in order to get more speed out of the camera and RAW?

Very strong. On the 600D you have to strech it by 166%. So I guess if you haven't noticed anything like that, it isn't squished and the EOS M is the only camera which has this issue. If you set the resolution in the Canon menu to 720p and record a raw video with Magic Lantern you'll see what I meant which squished.

@ Aborgh: Not at the moment. Otherwise the 600D wouldn't suck so much

Once the Magic Lantern version for the 650D/700D gets better and the RAW feature gets more stable it should be possible to get a bit more speed. The benchmarks show that the hardware can handle ~ 41 Megabyte/s write speeds. And maybe more. But even with the current 37 Megabyte/s you shouldn't be too unhappy.

You could see it at the beginning of this video

, but it looks quite round.

Yes, I did.
Right after I´ve used RAW2DNG the Pink Dots were Removed by pinkdotremover.
Ive converted the resulting DNGs into another format, i think it was tiff, dont know why i used that one ^^
In Adobe Premiere the tiffs were imported and rendered.

Fuma · « **Reply #113 on:** July 12, 2013, 11:53:11 AM »

I am using this card below:

mdfaisal · « **Reply #114 on:** July 15, 2013, 05:56:42 PM »

I Think I can confirm that 1280 x 720 24p, can record continously in raw video

im using
http://www.amazon.com/SanDisk-Extreme-Class-Memory-SDSDX-016G-X46/dp/B0037FLUYU

1. Im formated my new card with exFat in diskutility (im using mac)

2. Im using satriani 1st july, and copy all files from my old memory card (DCIM, ML, Misc, Rom.dat, autoexec.bin, 650 safe dumper) in to a new card

3. open macboot to create bootdisk in my new card, and prepare a card

4. put my new card in 650D and running ML

5. disable global draw

6. start recording raw video 1280 x 720, 24p

7. record until my card full

First Try:

left is my file size (more than 15 gb)
right is my my available free disk space

Second try:

mdfaisal · « **Reply #115 on:** July 15, 2013, 06:53:23 PM »

and this is my card benchmark, pretty much the same like spider

_DK_ · « **Reply #116 on:** July 15, 2013, 11:43:16 PM »

Hi,
I encountered a little problem.
I set the RAW video to 720p, but I only get files that are 8 pixels smaller on each side of the frame (1272 X 712).
Am I doing something wrong?

This bugs me because I have no idea how to stretch it, in Sony Vegas :/

saulbass · « **Reply #117 on:** July 16, 2013, 12:04:00 AM »

Hi,

I'm getting the following results with a Transcend SDHC UH1 32Gb card in a Canon 650D:

1280x720
16:9
card warm up off
small hacks off

The following frame runs:

1728
1491
1126
1665

Not bad for an approx. 36 m/s (benchmarked) low cost card. Good to know a faster card will give continuous 1280 x 720.

ML rocks!

Try to dissable global draw.

wacru1 · « **Reply #119 on:** July 16, 2013, 06:39:03 PM »

anybody running this on the 700d?

_DK_ · « **Reply #120 on:** July 16, 2013, 07:14:33 PM »

I got it working in 720p without stopping on a Sandisk Extreme 45MB/s 16GB.
I use the build from 14.07.

Just a little test shot of one of my pet geckos:

You can find settings, workflow etc. in the video description.
This was shot in low light, and it has barely any noise

Thank you so much for this! You guys are great

Can you please tell me if this card works fine with 1280x560 24p ?

95mb/s cards are too expensive for me and I'm thinking of getting this one.

P.S. I can purchase 95mb/s 8 GB or 45mb/s 32 GB and It will be great if someone can recommend me ^^. Thanks in advance!

spider · « **Reply #122 on:** July 16, 2013, 08:39:18 PM »

Continuous 720p24 16:9 works with that card.

I'd already done this.

I can't seem to get a screengrab of the benchmark that mdfaisal posted. How do you do this? When I run the 5min benchmark
I get writespeed buffer 2048K 31.0 Mb/s
Read speed 2048K 118.0 Mb/s
which doesn't match mdfaisals posting.

Than try to buy a new card

If you read my previous post, i bought sandisk extreme pro 45mbs 16gb that only get writespeed 21mbs

i think its a fake card. After using sandisk extreme 45 mbs i get writespeed almost the same as spider.

I think sandisk extreme 45mbs is the most affordable card that 650d can have 720p at 24fps raw video. But you have to disable global draw.

I dont know whether sandisk extreme pro can record 720p with global draw turn on.
I think we should ask members who has sandisk extreme pro 95mbs.
