Combine small video over a big video

I have a hd video(1920x1080) as a background over it i want to place 48 small video that will be trigger by key.

the small video are 160 x 160 to 300x 300 depending on the video.

I was using moviein, stoner to place the video and composite to mix all the source. but stoner affect the resolution. if I don’t use stoner it just fill the video in the composite.

My question how to place the small video at the good place over the background.

thanks

You can use the Over TOP.

see example. Change the translate parameters of the Over TOP to set the location of the small video. You can set it in fraction (as is done in example) or in pixels.
