Why is the uploaded video limited to 1? Why are uploaded videos not "Interpolated"?

Why is the uploaded video limited to 1? 

I'm wondering. Why two or four video files are not uploaded to the system. Thus, the lost video pixels can be completed by analyzing from the other video file. A perfect motion capture data can be obtained thanks to the video files with 4 different angles containing the movements of the actor in a scene.

Why are uploaded videos not "Interpolated"?

"Interpolation" process should be applied to the uploaded video file. It's important that animations look fluid. I'm sure not every user will upload a professional video file to the system. Uploaded video files should be converted to 60 FPS by "Interpolation" process. Missing squares can be added by algorithm. Thus, a perfect and fluent movement data can be obtained.
