Editing techniques: Flash Transition

Within my production, a pendant is used to stop time and it was important to make sure this is obvious to the viewer. One way to do this is using the transition effectively between the shot where he twists the pendant and the shot afterwards where he is in frozen time. After researching various options such as fading to white I decided that the best transition would be a white flash that takes the viewer to the next shot. The reason I chose this was because it gives off the idea something important has happened. The only hindrance about this transition is that it wasn't a preset on the editing software I was using so instead I had to create it myself. To do this I combined two separate video effects to make up the flash effect which were 'Fast Blur' and 'Levels'. Fast blur blurs the image quickly whilst the levels allow the colours to be changed. To make the flash effect I increased both the amount of blur and the amount of white every few frames until the image was completely white. The finished transition only lasts a second however it works well to make it seem like there has been some sort of change. Below is both a screenshot of how the transition was made along with a snippet of the production showing the transition.
