Recording Issue On Canon 550D/T2i

[Jimjambeal]

Hi all,

Firstly, apologies if this has been raised elsewhere.  I'm new to the forum and wasn't 100% on where this should be posted.

Anyway, the issue.....

I'm am recording video on my 550D/T2i the Magic Lantern.  The installation of Magic Lantern was no problem and this is the only issue I noticed.

I am getting the dreaded 'recording has stopped automatically message' after 3 seconds of recording at full resolution at 24fps.

I'm aware that cheap SD cards can be be a big issue with this, but I am using Sandisk 32g Class 10 cards so can't see the  brand/quality/speed of the card being an issue.

I'm really happy with video quality I am getting and just need to get over this issue, but am getting inconstant information on what this could be.

I have a basic knowledge of DSLR video, but fear I may be missing something.

Any help would be much appreciated.

Many thanks


Jamie

did you mess with any of the settings already? changed the bitrate maybe?

[Jimjambeal]

Hi, thanks for you're reply.

I have increased the bitrate, but didn't think this would effect it on a high class card.

I'll knock it down to see if that helps. Can you advise on an optimum bitrate and will having it lower effect the footage dramatically? 

[Datadogie]

With what I have read there is little to be gained upping the bitrate.

[Jimjambeal]

That's interesting to hear.

I'll drop the bitrate back to default to see what that does. Fingers crossed.

Thanks for your help.

With a class 10 card, 1.7 x bitrate already causes buffer overflow on my EOS-M. I'd guess it does so sooner on the older 550D...

Anything higher than 1.4 CBR (with sound) will cause buffer overflow in your 550D
