Trackuino intervalometer Video Mode not working on Elph 300 HS ixus 220

Trackuino was designed for A570IS Digic 3 and I am running Digic 4
The scripts takes photos file but not video.

function mode_video()
  blink_led()
 
  -- Switch to video
  capmode.set(capmode.name_to_mode["VIDEO_STD"])
  log_printf("video mode")

  -- Turn off the display if the user wants so
  set_backlight(param_display)

  sleep(500)
end


function take_video (secs)
  -- start recording
  press("shoot_half")
  press("shoot_full")

  log_printf("wait %d secs", secs)
  sleep(secs*1000)

  -- stop recording
  release("shoot_full")
  press("shoot_full")
  sleep(1000)
  release("shoot_full")

  -- wait for SD (get_movie_status returns 5 while recording, 0 or 1 when done)
  while get_movie_status() > 1 do
    log_printf("video status %d, waiting...", get_movie_status())
    sleep(1000)
  end
end

The tracku log shows th ephotos being taken as Photo #1 etc then says video mode then wait 12 seconds which is the length of the video but there is no video created and no indication of the screen that a video is being taken.

Thanks, only day 2 for me with chdk. I have interval photos working fine just stuck on video.

Your camera has a video button. The script was designed to start video recording with shutter.

You must change 'function take_video (secs)' in:
Code: (lua) [Select]
function take_video (secs)
  -- start recording
  click("video")

  log_printf("wait %d secs", secs)
  sleep(secs*1000)

  -- stop recording
  click("video")

  -- wait for SD (get_movie_status returns 5 while recording, 0 or 1 when done)
  while get_movie_status() > 1 do
    log_printf("video status %d, waiting...", get_movie_status())
    sleep(1000)
  end
end

Thanks for that. I am going to give this to a friend who is a programmer because when I change these lines my script will no longer take photos or video. Before it would take the prescribed photos and then stop when trying to take video.  Alex
