Video Import keyframes issue

I would like to import a video, where each frame is a keyframe, meaning i can copy certain frames and use them later on.

the only solution i think i have for this, is to take the video into final cut and export it as jpgs and make each jpg a frame, but i think this will make the file huge.

when i import right now, it makes one keyframe and then the embedded video part.

any help please? thank you
