The main river in Bangkok. A day with great clouds. I used a polarizer on my PMW-EX1 and shot at 1 frame every 5 seconds in 1920 30p. I under-exposed (in retrospect I think maybe a little too much) to hold all the detail in the clouds. I rendered the clip to Apple ProRes422HQ. I brought up the levels and saturation in FCP using the 3 way color corrector, correcting the Gamma and highlights. Then I exported to compressor using H264@5Mbs.
I have been noticing a choppiness in my cloud timelapses with the ex-1. I thought it was a compression (XDCamEX) or a playback issue (MacBook Pro, 2.4 GHz, 2 GB RAM, playing off internal Drive) But I have tried recompressing it to every flavor of codec and frame rate to no avail. I have also tried playing the original back on a Mac Pro with more and faster processors ( can't remember exact stats...) and that didn't seem to make a difference either. Also, vimeo's compression makes it even choppier which I believe is a result of the conversion to 24p. I wonder if conforming it to 24p in cinema tools will help? Also, I think I will shoot the timelapses at 24p and with a higher sampling rate and speed them up further in post. But isn't that the same thing anyway???
Then I noticed in this video that the ships are silky smooth and the CLOUDS are not!?!?! hmmmm. maybe the clouds are moving at too high a rate to be smooth @ 1 frame every 5 seconds? Though this is not born out by the fact that when I sped the clip up 2x (This is the sped up clip, to see the original clip, go to: vimeo.com/1441371) it got SMOOTHER!!! Any thoughts? have to do some more testing. 2 things I will try: Shooting at 1 frame every 2 seconds and Shooting at 1920 24p.

Hmm…it looks like things are taking a while to load. Try again?
