I have a very fast card already - [UDMA 7](https://en.wikipedia.org/wiki/UDMA) - so I very much doubt this is the issue. I've also tried with small, fine JPEG and it doesn't help.

<p>I'd like to take 1 Hz and sub-second timelapse videos with my Canon 7D. I've tried both <a href="https://play.google.com/store/apps/details?id=com.dslr.dashboard" rel="nofollow noreferrer">DslrDashboard</a> and <a href="http://www.magiclantern.fm/" rel="nofollow noreferrer">Magic Lantern</a>, and couldn't figure out how to set the timelapse any faster than that. Worse, <em>both</em> of them ended up taking photos at such a jittery rate that I could <em>hear</em> it was completely off kilter. The camera would take one photo, then wait for a couple seconds before taking two in less than half a second, and so on, making the result unusable for video making. I was using manual mode, and shutter time, f-stop and ISO were <em>all</em> set to static values.</p>

<p>The camera is otherwise perfectly capable of taking many photos per second, even at RAW quality. Is there some fundamental issue with the timing used when remote controlling (and even when using custom firmware) causing this, or did I miss an important setting to make it all work? If this is simply an issue with both these products, are there other software products (preferably FOSS) which will reliably take 1 Hz or faster time lapse series?</p>

Should this question be deleted? The photo.SE question got much more response, and by now it's just a dupe...
