How Is This Fast Edit Done? (Beyonce Video)

[Rob Grauert]

my friend did something similar to this in high school. all he did was show a few frames of each clip and alternate them. if it’s done fast enough, i guess your brain just sees it as one image.

You can use the blink filter for this Lillian … put your 2 video sources on 2 separate layers (eg v1 and v2) then apply the blink filter to the upper layer and adjust the settings to the rate you want that upper layer to flash on and off.

Have a look a Luca’s Dual Flicker filter too, adds a really nice “randomness” to the whole idea and a great example of a good idea well realised:

the fastest way to cut is cut every field.

For that you need a key signal that seperates the fields.
An example here:

If you use this as a matte between two layers, you get just a field of each one.
(put two clips on top of each other, apply image mask filter to the top one, drag my clip to the image setting)
If you watch on an interlaced client monitor, this will blink 50 / 60 fps

BUT, no idea how it will look after de-interlacing, and that will happen if you upload to Youtube or alike.

Uhhh… there’s an effect? Where? Must’ve been distracted.

Serious Q though – I’m surprised this would pass the Harding test (photosentitive epilepsy) but I guess if the luminance values don’t change much and the position of the centre of attention isn’t changing, you might get away with it?
