frame rate up-conversion

hello im a beginner in matlab. i want to increase the number of frames in a video. i have tried the interp1 but the results were not good. now i want to increase the frames in transform domain and using wavelet. my sequence has 9 frames of 512*512 pixels. so do i have to go through pixel by pixel in frames and use one dimensional dwt? for example i decompose all 9 frames to approximation and detail. and i want to produce an approximation and detail between each pixel in consecutive frames. what should i do?
