For my Grampa's 86th birthday I decided to break out my Nikon D40 and take as many pictures as I could fit on my 2gig card. Turns out, I was able to fit just over 900 photographs. I ended up taking 853 photos with the intention of creating a stop-motion/timelapse type of movie. The end result came out pretty close to how I was imagining it to be.
It was a fairly simple process.
First I took all the photos I wanted, a lot of the times firing off several bursts in a row in order to get the consecutive motion look
Imported all 853 photos to my hard drive
Used Photoshop to batch process all the photos to 1920x1080 (HD resolution)
Jumped over to Quicktime Pro and selected "File > Open Image Sequence," and imported all my stills at 12 frames per second
Exported my movie out of Quicktime Pro as an Apple Pro Res (HQ) mov file
Imported that mov file into Final Cut, mainly for color correction, title and music welding
Exported that file out of Final Cut, compressed for the web and uploaded to Vimeo.
Voilà. Total production time: About 4 hours (including photographing the event). Simple and effective.
