Video Editing terms


A cinematographic technique where each film frame is captured at a rate much slower than it will be played back.

What is a time-lapse in video editing?

Time-lapse in video editing is a technique where the frequency at which film frames are captured, also known as the frame rate, is much lower than that used to view the sequence. This means that when played at normal speed, time appears to be moving faster and thus lapsing. It is a unique form of photography that allows time to pass at a pace that can be perceived by the human eye.

This technique can be used to capture scenes that evolve slowly. For instance, it can be used to show the process of a sunrise or sunset, a blooming flower, or the movement of clouds. The process involves taking numerous photos over a period of time and then assembling them to create a continuous sped-up sequence. Time-lapse in video editing can create a bridge between the cinematic and the real world, offering a visual representation of how time can be manipulated.

How to create a time-lapse video in Adobe Premiere?

Creating a time-lapse video in Adobe Premiere is a straightforward process. First, import your images into Adobe Premiere. Go to File > Import, or simply use the shortcut Control/Command + I. Select the first image of your time-lapse sequence and check the box that says "Image Sequence". This will treat the series of images as a video file. Drag the file to your timeline.

Next, adjust the speed of your time-lapse. Right-click on the clip in the timeline and select "Speed/Duration". Here, you can adjust the speed of your time-lapse. The higher the percentage, the faster your time-lapse will be. After adjusting the speed, you can add effects, transitions, or music to enhance your time-lapse video. Once you're satisfied with your video, you can export it by going to File > Export > Media. Choose your desired format and click "Export".

What is the best interval for time-lapse in video editing?

The best interval for time-lapse in video editing largely depends on the subject matter and the desired effect. For slow-moving subjects like clouds or the sun, a longer interval such as one shot every 30 seconds to a minute might be appropriate. This will allow enough change to occur between each shot to create a noticeable difference in the final video.

On the other hand, for faster-moving subjects like people or traffic, a shorter interval such as one shot every 1 to 3 seconds would be more suitable. This will capture the rapid movement and activity in a way that can be effectively sped up in the final time-lapse. Ultimately, the best interval is the one that best captures the movement and change of the subject matter over the desired period of time.

How to edit time-lapse videos in iMovie?

To edit time-lapse videos in iMovie, you first need to import your time-lapse video into the iMovie application. Open iMovie, click on "Create New" and select "Movie". Then, click on "Import Media" or use the drag-and-drop method to import your time-lapse video. Once your video is imported, it will appear in the "My Media" section of iMovie.

To edit the video, drag it from the "My Media" section to the timeline at the bottom of the screen. Here, you can trim the video, add effects, and adjust the speed. To trim the video, simply select the video in the timeline, move the cursor to the beginning or end of the clip until it turns into a double-sided arrow, then drag it to your desired length. To add effects, select the video in the timeline and click on the "Filters" button above the viewer. Choose the filter you want to apply. To adjust the speed, select the video in the timeline, click on the "Speed" button above the viewer, and adjust the speed slider as desired.
