    I use PiCapture SD1 (first time).
    I tried capture video from two different composite camera.
    They good work on the TV (RCA input).
    There are uploaded two small video files.
    https://files.fm/u/jfwhwdgm
    First rear view camera 656*492 (vid2.h264)
    Second night visio 720*480 (vid2.h264)
    Both video files have resolution 640×480, but
    video size taken only quater (fourth) part.
    Note: video frame was taken whole (another words all was captured).

    As described in the documentation, you must set the “camera mode” to match the expected video resolution. This would be mode 6 (“-md 6”) for the SD1.

    If you still have issues, please post the output of PiVideo query (“pivideo -q all -v”. It is easier to demonstrate issues with raspistill than with raspivid.
