help on these effects?

how do you do the following fx?

(flicker spread)

… 0:17 , 0:20 , 0:23



..0:16 - how the video pauses and flickers etc



..super slow motion at 0:01

For clip 1 + 2, probably use a plugin like mGLITCH from motionVFX.

Though the second clip looks like it is two freeze-frames layered on top of each other with the top layer having the background masked out to show only the singer. The glitch/flicker effect is then applied to the freeze-frame on layer 1.

For the slow motion effect, you'll get best results shooting at high frame rates.
However, if you don't have access to such a camera, you could cheat it by shooting at the highest frame rate available and then using either Twixtor (expensive) or optical flow retiming to slow down the clip.

Hope this helps,

Good Luck.
