When you want to place a static image before the first frame of a video, it typically involves using an image as the lead-in frame or referred to as the 'opening frame' of the video sequence. This can be achieved using video editing software. Here are the general steps and an example:

Using Video Editing Software (e.g., Adobe Premiere Pro)

  1. Import Assets:

    • Launch the video editing software.
    • Import your video file and the static image file intended to serve as the first frame into the project.
  2. Create a New Project:

    • Create a new video editing project.
    • Set the project's resolution and frame rate as needed.
  3. Create the Timeline:

    • Drag the video and image files onto the timeline.
    • Ensure the image file is positioned before the video file.
  4. Adjust the Static Image Duration:

    • Select the image file and adjust its duration on the timeline. This duration determines how long the image will be displayed before the video begins.
  5. Add Transition Effects (Optional):

    • If needed, add a transition effect, such as a fade in or fade out, to smoothly transition between the image and the first frame of the video.
  6. Preview and Adjust:

    • Preview the timeline to ensure everything functions as expected.
    • Make adjustments if necessary to ensure a natural transition between the image and the video.
  7. Export the Video:

    • Once satisfied, export the video file.
    • Choose the appropriate format and resolution as needed.

Example

For instance, if you are creating a short film and want to display a static poster representing the film's theme before the video plays, you can follow these steps:

  • Import your film file and the poster image into Adobe Premiere Pro.
  • Set the sequence parameters, such as 1080p resolution and 24fps frame rate.
  • Drag the poster image to the beginning of the timeline, then place the film file after it.
  • Set the duration of the poster image to 5 seconds to give viewers sufficient time to observe.
  • Add a fade-out effect to smoothly transition the poster image to the first frame of the film.
  • Export the video and ensure the output settings are compatible with your distribution platforms (e.g., YouTube or Vimeo).

By doing this, you can effectively add a static image at the beginning of the video, presenting it to the audience before the video plays. This approach is widely used in various video production contexts, including films, presentation videos, and educational materials.
