Slowmotion 48fps with Canon 5D Mark 3 Question
« on: August 03, 2014, 09:57:21 PM »
hello,

today i installed the latest nightly for my Canon 5d Mk3 (30th July 2014)

i wonder if it is normal that when recording slowmotion video with 48 fps, the recording stops earlier when recording to both media cards with spanned files method...

ml files are on the sd card, the cf (kb 64gb 1000x) is free,
mlv is selected, also 1280 50 from canon menu.
when i record to only the cf card, the speed is better, cause i can record a longer shot before frame skipping.
when i record to both the cf and sd card, the write speed is decreased..?

is this a known behavior?

thx sw

There's a thread 6 topics below this one about slow motion on the 5D3...it would seem to be a good place to have put this question in.

It's a related enough thread that your question would fit.

Well, why not merge the two threads into a single one discussing slow motion on the 5D3? I don't think it's that far off.

But I'm sure we could both continue going back and forth on this while the OP does't get any help whatsoever on his issue.
