The H.264 format doesn't work well with video editors on lower end systems, It would be a lot easier (and fluid) to edit an image sequence.
To do this, simply press CTRL to bring up the Image sequence option (IMG) in the movie export dialog window, this will render your clip in a lossless format, such as PNG/TGA/BMP.
