Uploading video to Social network from iphone

Uploading video to Social network from iPhone.

Fails with html syntax popup on phone, same video from pc reverts back to the page with no upload.

The pop on the phone say unsupported format(mp4) is this correct that it doesnt support mp4? is there a fix please?

in fact i just converted to avi and posted to a page within the site, it posted but with blank screen,wont play. any help would be great :slight_smile:
