What is this Glitch Effect

Thankyou all for your help.... plenty of avenues now to investigate.... I too am much more interested in trying to create it myself however it would be interesting to see just how close to the subject transition everyone could get if it were a competition with a time limit .... !   

Looks like the After Effects Animation Preset called Bad TV.

Like other people said you should probably just use a preset.

If you have After Effects, though, it's much easier. You can use effects such as Shift Channels, Fractal Noise, and Displacement Map to get a glitch effect.

It's not included within Premiere as a transition per say. There is a good chance it could have been used from a transition plug-in pack. A lot of those are sold online and you can download transitions that you drag onto clips or adjustment layers.

That said, something similar can be made from scratch from tools and effects available within Premiere. There's an infinite number of ways to do glitch transitions. Since glitches are mostly random in nature, the skys the limit as to how you exactly "glitch" something out:

• Duplicate video layers on top of each other, try some blending modes, and offset scale and position of layers
• Arithmetic or Channel Blur can help simulate the split of RGB channels
• Mosaic or Posterize can help simulate a degrading image quality.
• Offset can help simulate a rolling image
• Overlays of static/glitch can be blended in as well(although make sure that you either purchase, or fall within the license to use material that isn't yours)

I'm a big proponent of doing it from scratch just because it gives you freedom to do what you want, and helps you learn the capabilities of the software more (and it can save money). However, I get that time constraints do exist, and this is where those transition packs come into play. If you want to DIY, search YouTube as there are tons of tutorials out there as to how to make a glitch effect on your footage.
