Is there any way to download the original hi res video from the spark through the app?  I don't want to always have to pull the micro sd card to get quick videos off of it.

Nope, at least not that I know of.

Please export the original video through SD card.

you can connect your spark via usb to your computer and extract them that way.  Prevents any issues with SD cards in the future (taking out and clicking back in).  Hope this helps.
