GH2 Problem Speeding up 24p

I've been experimenting with time lapse video and shot a few minutes of clousds the other day, to be sped up in post. It looks though like something went wrong, as the clouds in my footage appear a bit choppy at 1 second intervals and i'm wondering what may have happened. First, here's the footage:

This is 24p, 1/50, f/9 (or so), iso 160. I dropped it into a 24p timeline in Premiere and sped it up 1000%. Exported to Cineform, then squeezed it with Sorenson @ 8000kpbs.

You can see that the clouds tend to "hiccup" every 1 or two seconds.... and it did the same thing within Premier and after i exported it.... any thoughts on what could be going on here?
Thanks.
 
Its probably the camera, depending on your memory card speed and photo quality setting. Sometimes the camera wont have it's cache clear and isn't ready for the next photo, so it'll just not take the photo... but skip to the next photo trigger.
I've had this problem when capturing with a standard Class 10 card, I had to reduce my photo settings as well as set the interval wider.
I've found around 3secs is perfectly fine for most photo settings.
 
I'm not sure if I understand....I was shooting video in 24p and then speeding it up. From your reply it sounded as if you were referring to still shooting...did I understand you correctly?
Thanks for your help.
 
Yes, im sorry... I misread your post. its possible there is a render performance issue in your workflow.
At what point do you see the "hiccup"? After you export from Premier, or inside Premier? Typically, when i have any "play back" issues, its because my render cache is all mixed up. So i need to clear the cache and render again. (Often happens when im slowing down footage)
Also, when you export... dont use your "cached render files". Have Premier RE-RENDER everything upon export.
What type of hard drive are you using for all your files? Dont use USB 2 drives, stick to your internal Hard Drive or a faster connected drive, ie: Serial, Firewire, Thunderbolt, USB 3.
 
Sounds like a good suggestion, though I'm new to premier. How would I go about clearning my render cache and is it the same process I need to repeat before exporting the clip? If you could run it down for me a little I would be interested in trying your suggestion.
I'm using internal SATA3 drives, 7200 caviar black. One system and other for media - both internal.
 
UPDATE: Partial Solution

UPDATE: Partial Solution

is there some way to get Premier to read the framerate as 24000 instead of 24p so it will drop unnecessary frames while importing into the 24p timeline? I did this successfully in VirtualDub, but the Premier couldn't read my exported VirtualDub .avi file, and the Virtual dub file was extremely large. Is there a way to do this natively in Premier without having to export to VirtualDub?
thanks.
