![]() The software used to assemble the video may also impose limitations. Unfortunately when shooting the night sky it is unrealistic to expect exposures to take less than about 10 seconds even at high ISO. If that still seems like too much work, we can settle on shooting 1 minute exposures and have the shooting done in a 5 hours. Assuming we are shooting these at night with 2 minutes each exposure it will take 600 minutes (a mere ten hours!). Perhaps we shall start a little less ambitiously and collect 300 frames – enough for a 30 second animation at 10 frames per second. Yes, that is a LOT! However often a frame rate of 10-per-second is acceptable, so only 3,000 images are needed – still quite a lot. A movie typically consists of 30 frames per second, so to shoot 5 minutes of video one needs 30 frames per second for 60 seconds x 5 minutes. An important consideration is the frame rate – that is the number of images shown per second. On the other hand, my time-lapse are byproducts of my star trail shots and I always shoot those in maximum sized RAW mode. Usually pictures used to create a time-lapse will be at relatively low resolution (1920 x 1080 or smaller) so shooting them in large format, RAW means extra work will be required to assemble them. Shooting Time LapsesĪ time lapse requires “frames” – individual pictures used to create the end result. The method used to create the animation will depend on the number of frames available and the intent. ![]() I later did a similar animation using a tripod. An early example of a daylight animation chronicles my son scaling a rock in Zion. Not all time-lapses need be created from night images, however. I will cover the technique to create this in Part 2.Ī more elaborate effort with music, stacking and credits is this one created from 8 hours worth of images using the tool Picasa which is free and available for windows and mac: This video contains no music or titling as those are not supported by StarTrails.exe. The vertical format works well with the portrait mode images. “ Star Races” was created using the stacking features of StarTrails.exe (Windows program) and composed into a movie using the “Animation Feature” of that same tool. My first foray into animation looked like this: One of the nice little benefits of using the stacking technique to create star trails is that you can take those many frames and animate them.
