Development of videos: square format to circular

Finally worked out how to apply a circle template made in Photoshop to a video in Premiere. Eventually realised I had to leave the background transparent, then could drag it over the whole length of a video and then the images would be focused within a circle. I made two different size circle templates and used the smaller as the larger was too large and had its top and bottom cut off in the final video.

Also had to learn how to crop videos so that I could play two or more side by side or in separate parts of the screen. Difficult as the video looks fine before it is saved then when it is played back the defects become obvious i.e. bits cut off etc. Very frustrating and time consuming.

 First videos before the circle template: the square format doesn't work: not focused enough, diminishes their strength. Experimented with double image of nit, not successful: made it weaker rather than stronger.

Difficulties getting the two videos the same size, cropping them not that simple. They need to be in a circle format: need the focus.
