    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.
    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).

    raspivid -w 640 -h 480 -p 0,0,640,480 -o vid.h264 -v

    Preview Yes, Full screen No
    Preview window 0,0,640,480

    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.


    Thank you, seem works 🙂
