I love the time lapse video recording feature on my Elph SD870 IS, but am a little annoyed with the limited interval options... only 1 sec. and 2 sec. are available, and only at 640x480. I'd really like to see an option to do time lapse video at 320x240 for easier uploading to the web, and additional interval options such as one-half sec., five sec., ten sec., thirty sec., one min. etc. I wonder what the best interval options would be to add to the 1" and 2" options that already exist in the camera.
