Forgive my spelling, I'm posting this from my mobile.

I've recently decided to record videos to help teach a visual language. My camera likes to boast it can record in 1280; its a cheap camera about £75 so the quality isn't amazing. But its okay.

Anyways, it has some other settings for lower res, but I figure might as well record in a larger size in case the need arises for a bigger source file in the future.

I've been looking at jw player to play the converted files (mp4 to flv I think). What do you think a good size would be to convert to? I want to to look nice and clear remembering it is a visual language so lip patterns, facial expressions, body movement, fingers etc are all important, sound is not that important but I would like to have a choice to toggle captions. 

Thanks for any help,
any advice apreciated, first time I have done a video project!
P.s. If anyones interested its BSL.
