Tips for making a video abstracts

A video abstract is a type of video in which you briefly discuss and explain your paper in a short presentation. It should be within the conceptual scope of the article and directly support its conclusions. Note that video abstracts are subject to peer review.

  • If you decide to use an interview setting, the person doing the interview should be someone other than the one doing the filming.
  • The person being interviewed doesn't have to look straight at the camera; a slight angle often works better.
  • Use a tripod as this will make your video steady.
  • Tell a whole story and talk about your article with feeling; act as if you are addressing a class of students.
  • Use different techniques, such as animations, to explain your article. You can also make scene shots of your surroundings like your institute, building, environment, etc.
  • Use enough light during recording, but avoid any bright light coming from behind the person being interviewed (windows, sunlight). A light source coming from behind the camera gives the best results.
  • Anyone speaking should not stand too close to walls to avoid shadow and possible echo effects.
  • Speak clearly and loudly enough for recording. Use of a microphone is recommended, but don't place it too close to your mouth: breathing noises should be avoided.
  • Clearly state the names of the spokespersons and provide legends, titles etc.
  • Edit your video to improve the recording. You can make use of software such as Adobe Premiere Elements, Windows Movie Maker, iMovie, Final Cut Pro, Cinelerra and others.
