Hello everyone ,
I've installed Magic Lantern on my Canon 70d without any problem , it works just fine , but there is still something :
When i shoot Raw video , in every mode it skips frames after 7-8 seconds and my video stops :/
I have a lexar 60mbits/sec , and it still does it when i choose a 54mbits/sec video resolution , i have tried the different options in the menu's like the Sd card ''warming'' but nothing seems to work .. I usually shoot in 2.35/1 aspect ratio on 1824x776
Also , there is a limit in raw video (i think all of you know) who says that i can't go over 1824 in the current video mode . Is there a way that i can go over this limit ? What is the ''current video mode'' ?
A know i can ignore the frame skipping , but it's not really a solution for me :/
Thank you a lot , i would me recognizing if someone would help me use this wonderfull feature properly :D
70D's SD-card interface is limited to about 41 MByte/s write rate.
And I really hope you mixup bit and byte ...
Yeah i never really understood the difference (i know a byte is a group of 8 bits ) , but i don't know which one is in my case ..
I have a Lexar 400x 60Mb\s , so is it bytes or bits ? ..
So my 70d doesn't even support my lexar's speed ?
I just ran a benchmark on my canon and it says write speed 20MB\s , what the heck ?
Thanks for your answer
Press Play button after starting benchmark.
And manufacturer numbers will be valid for read, not write operation. Write numbers can be significantly lower.
Alright , i get it . So what sd card should i choose to make sure the write speed is the best i can get (41MB/s) ?
41MB/s is just a peak for some milliseconds. You will get 37-39MB/s for raw/mlv recording. take a look here for cards:

I am using Sandisk Extreme Plus. But the cheaper non-plus should do the trick, too.
