Learn how to make your explosions stand out with just a few extra elements like flying debris, shockwaves and camera shake
To create a convincing explosion you will first need to record your base footage. Simply record your clip as normal and at the time of explosion, have your actors either jump away as best as they can or simply stand still. We will cover them up anywayNext, film some footage of your actors actively jumping away from the explosion. Try to get them to start the jump with the same position, direction and posture they had in your base footage as we will stitch those clips together. Feel free to take a run up to the jump, that's the part we'll cut away
Place the jump footage on top of your base footage and align the jump so it cuts in at the correct time when the explosion hits and it looks like your actor is being flung away from a standing position by the power of the explosion!
If you see any twitching during the transition, you can apply masks around your actors and feather them out a bit to make the cut less obvious. I've cut out the bottom left of my jump footage so there is no twitching in the foliage of the trees.
One thing to make your explosion look more realistic is to create a few elements that will be flung out away from the centre of the detonation. Let's look at how we can do that!
