Hi all,
just a quick note that I wrote an article for Planet Quark recommending Miro Video Converter:
http://www.planetquark.com/2013/05/14/how-to-encode-videos-for-the-retina-ipad-or-samsung-galaxy/
For me the tool has always worked perfectly, I didn't have any problems with the videos I create with it and the one-click presets really speed up things.
Give it a try and let me know your experience please.
Thanks
Matthias
