A Video Abstract is a short video summary of a journal article:
Basic steps for creating a video abstract:
Step 1. Select your recording equipment and software
Step 2. Decide whether you want to describe your paper from on or off camera, and whether to include slides, video clips or animations.
Step 3. Write the script (it doesn’t need to be word-for-word). 120-150 words are approximately a minute of video. Aim for 750 words or fewer.
Step 4. Add intro and outro music that’s licensed for reuse
Step 5. Set up captions/subtitles
