I have a time lapse project that I plan to shoot with
the HDX 900 and would like to duplicate the fluid results that we all admire from the "Planet Earth" series. The client cannot provide the window of air time yet but I'm looking for recommendations for the best frame rate/interval record rate to use.
Also, should the shutter be employed and what about the shockless white balance circuit since the shoot carries over from daylight to night time?
Of the time-lapse shots I have done. I leave the white balance set to one setting. It looks more natural that way. The light gets warmer as it sets which looks correct. You can always do some correction later in post.
2nd, the camera does not really create a final time-lapse in-camera. You have to edit it down in post by taking out frames. It's not that hard, just wanted to let you know. I've found that editing down to 1 frame at a time is cleaner than doing 2's or 3's.The only issue is many edit systems may not be able to play that back in real-time. Not a problem, just export the single frame edit timeline to a stand-alone composite clip. (Your editor will understand)
As far as timing goes, just calculate the time for the final shot say 30 sec. And then figure how much time you want to leave the camera setup. For example 4 hours. Then you can figure out the setting to achieve that time.
30 finished seconds = 900 frames at (30fps)
4 hours = 240 minutes = 14400 sec.
Divide 14400 by 900 and you get 16.
So, set the camera to record every 16 seconds = 900 frames in 4 hours. Adjust for a 24fps project.
That's just a starting place. You can change that depending on how fast you want the sky to move or if you have a specific shot you want to create.
For example I did a shoot for a casino where they had this cool neon sign. We wanted to get the sky setting behind the sign. What determined the speed was the length of the shot 4 sec. Thus, I set the camera to create a 4 sec shot (120 frames) in approx 90min. I set the camera to record every 45 sec. 90 min = 5400 seconds divided by 120 frames = 45
See the formula? For reference, cool cloud motion shots are usually gotten by recording approx 1 frame every 20-30 sec. Faster is cool too, but slower than that doesn't work for me as it's not as much an effect.
The HDX 900 does in fact create the time lapse in-camera. I tend to set it to capture 2 frames at a time at whatever interval you need for the length of your final shot. All the math is done for you in the menu. That worked nicely for an 10 second time lapse I shot showing a commercial jet from it's arrival at the gate, crews offloading/loading luggage and leaving. That took about 45 minutes. The HDX 900 did the time lapse and I was able to view it there completed about 15 seconds after I hit stop. I agree with Ernie that 1 frame capture for cloud stuff looks nicer than if slower.
aloha from maui. i was interested in finding out what formula you found useful in sunsets down da shore. i lived in ocean city NJ before i moved to hawaii three yeras ago. i have a shoot tomorrow and the client wants a sunset time lapse. any help would be appreciated.
