Interpolating Frames of the Video

I have two videos of 1 min each. First video has 900 frames whereas second video has 600 frames. So I am trying to interpolate second video to have 900 frames. Can anyone tell me how this can be done?

Have a look on interpn or run a loop for each point using interp1.

interpn gives NAN values.what to do?
