In my last post I showed how to combine a series of still photos into a single “star trails” image. I thought it would be cool to turn that same series of images into a time lapse movie, and it turns out that’s really very simple to do in Adobe Photoshop.
Since movie images can be much smaller than files intended for print, I began by creating an action in Photoshop to convert my original files to 400×600 jpegs in the sRGB color space. I named my action “Save for Video” and the steps in my action were:
- Covert to sRGB
- Resize to 400×600 pixels
I then used Photoshops File>Automate>Batch command to convert my file of original images to the smaller size and save them in a different folder. Note that I selected the check boxes to override the action open and close commands.
To turn the resulting folder of images to a video file I used Photoshop’s File>Open command to select the first image in the sequence. On the bottom of this dialogue box is a check box labeled “image sequence.” Make sure you select that check box and then open the image. You’ll be asked to identify a frame rate–I chose 24 fps.
At this point you’ll probably want to navigate to the Window>Timeline command to open the timeline dialogue box at the bottom of your screen. Click on the play button to see your video on action!
To save your video go to File>Export>Render Video. This will open a dialogue with a confusing array of options. But I just named my video, indicated where I wanted it saved, and left all the other settings on their defaults.
