I've got 14 PNG images (here but not important) that I want to put into a 2 minute loop at 15 fps.

Photoshop CS3 seemed the best tool for this so I opened them as an image sequence* and did File -> Export -> Render Video and exported as an AVI.

However I only had 14 images so I used a script (here but not important) to duplicate them as 1805 images (approx. 2 minutes of video).

When I repeated the Photoshop steps, the resulting file size was 55 MB as opposed to the original 429 KB.

All the video actually needs is the first 14 files to link to and then repeat (lossless).

What codec can I use which will do this? How do I use that codec? (I'm on OS X Lion).

I need it as a video, not a GIF.

*(Open -> first file -> tick image sequence)

Do you need it to be fully lossles? or a video with very good quality where the loss cannot be seen by the normal human eye good enough? –  d33pika Jan 21 '13 at 9:53
Also what is the size of the images? Why do you expect it to be 429KB? –  d33pika Jan 21 '13 at 9:54
@d33pika 429 KB was the size when I exported just the first 14 images as AVI. It doesn't need to be good quality at all, it's just an animated GIF. I was suggesting lossless because it only needs the first 14 images, and the rest are the same. –  gadgetmo Jan 21 '13 at 15:39
@d33pika compressed the 55mb file as zip with highest compression option, it got it down to 44mb. I tried 7zip and it got it down to 327KB. –  gadgetmo Jan 21 '13 at 15:42

Lossless compression means there is no loss when image/video/data is compressed, http://en.wikipedia.org/wiki/Lossless_compression. Example: zip/gzip. It does not mean repeating files. To create a video out of images using ffmpeg follow commands in this link : https://ffmpeg.org/trac/ffmpeg/wiki/Create%20a%20video%20slideshow%20from%20images

On Mac OS X you can install ffmpeg by following these steps: http://www.markszulc.com/blog/2012/09/03/installing-ffmpeg-with-h264-support-on-mac-os-x-mountain-lion/
