Technical answer about SD technology:

Each model of SD card is built to certain specifications, but not all are equal.

First of all, there are 3 major types of SD cards.

SD
SDHC
SDXC

SDXC is new, so as best as I can tell, it is irrelevant to picture frames.

SD devices cannot read SDHC cards, however SDHC devices can read SD cards so you would need to make sure that the picture frame reader could read SDHC cards.

On the retail market there are a few SDHC cards that are 200x rated, or 30MB/s transfer capable.

To stream HD video you only need 3-4 Mbit/s.

So SD cards are more than capable of handling your images.

Non Technical Answer:
They sell digital frames that can play movies... it would be easier to just capture the frames, slap them together in Windows Movie Maker, and push that as a movie on an SD card.

Is there a Youtube clip of what you want?

If I can get the clip on Youtube, I can download it, drop frames, and convert it to whatever format he wants.
