Revision as of 22:16, 29 December 2015
Canon P&S cameras are limited to a 4G file size when saving video files on a FAT formatted SD card. Listed below are three scripts that will automatically restart the video recording process periodically to overcome this issue.
Script 1
The first script is a simple uBASIC script that can be used to periodically restart video recording to get around this 4G file size limit. It repeatedly creates a new video file after a user defined interval, allowing recording until the SD card fills with only a brief gap between each video file. Save it to your SD card with a .bas extension (ex: video.bas).
(script 1a is for camera that do not have a video button)
@title MultiMovie 1a
@param x minutes per file
@default x 10
press "shoot_half"
sleep 2000
release "shoot_half"
:loop
print "segment started..."
click "shoot_full"
s=get_tick_count
do
sleep 500
until x<=((get_tick_count-s)/60000 )
click "shoot_full"
do
sleep 100
until get_movie_status=1
goto "loop"
end
. (script 1b is for camera with a seperate video button)
@title MultiMovie 1b
@param x minutes per file
@default x 10
press "shoot_half"
sleep 2000
release "shoot_half"
:loop
print "segment started..."
press "video"
sleep 2000
release "video"
s=get_tick_count
do
sleep 500
until x<=((get_tick_count-s)/60000 )
press "video"
sleep 2000
release "video"
do
sleep 100
until get_movie_status<2
sleep 1000
goto "loop"
end
Script 2
The second script is a slightly fancier version of the first script, with improved status messages, the ability to index to a new file by pressing the "SET" button and the ability to disable the backlight by pressing the "DISP" button. Note : when the LCD backlight is off, there is code to blink one of the camera LED's to indicate that the script is still running. You may have to change the LED number from 4 to something else for your camera in two places where it say set_led 4 0
The script only works on cameras without a dedicated video button.
@title MultiMovie 2
@param x minutes per file
@default x 15
f=0
print "recording started..."
press "shoot_half"
sleep 1500
b=1
l=0
:new
f=f+1
click "shoot_full"
if f=1 then release "shoot_half"
print "starting file :";f
e=get_tick_count+(x*60000)
p=get_tick_count+1000
if b=0 then set_backlight 0
:loop
if is_pressed "set" then goto "reload"
if is_pressed "display" then
if b=0 then
b=1
set_backlight 1
sleep 1000
else
b=0
set_backlight 0
sleep 1000
endif
endif
t=get_tick_count
if t > e then goto "reload"
if t < p then goto "loop"
p=get_tick_count+1000
m=(e-t)/60000
s=((e-t)%60000)/1000
cls
print "file:";f,"time left:";m;"m ";s;"s"
if b=0 then
if l=0 then
set_led 4 0
l=4
else
l=l-1
if l=0 then
set_led 4 1
endif
endif
endif
goto "loop"
:reload
print "reloading..."
click "shoot_full"
do
sleep 100
until get_movie_status=1
goto "new"
:restore
if b=0 then set_backlight 1
if get_movie_status=4 then click "shoot_full"
print "recording halted"
end

Script 3
Listed below is a more sophisticated script written in Lua by msl.
This script allows you to :
- turn the display on & off by pressing the DISP button or down button,
- halt the script by pressing the MENU button
- restart recording by pressing the SET button.
- zoom in & out by moving the cameras zoom lever
- refocus by "half pressing" the shutter button
It works on cameras with and without a dedicated video button.
Save it to your SD card with a .lua extension (e.g. vid_ext.lua).

end
until is_key("menu")
