What info do I need to know about uploading videos to my netAdventist website?

The video size limit is 250MB each on all our servers. If your video is larger you can consider compressing it down or dividing it into parts. 

Only flash format .flv, Windows media video .wmv or .mp4 with a codec based on H.264 will play on netAdventist. 

Some use vimeo or youTube and then put the link on their site. 

Two options to convert video formats for free:
