How to make a ti me lapse
We’re making a time stack here, but seeing as you’ve got the images for a time-lapse sequence, why not see how they look as a moving video too? To do this, simply go to File>Open, select the first image in your sequence, then check the ‘Image Sequence’ box at the bottom of the Open dialog. Hit Open and choose a frame rate such as 30fps, then go to the Timeline Panel (Window> Timeline, CS5 extended or above) and hit the play button. The sequence will render slowly. Once it’s done, hit play again to view it full speed, then go to File> Export>Render video to export it in a video format.
