So currently, I have a 720p version of Ironman (RMVB) and a 720p version of Avatar (MKV) and since I'm planning on getting an iPad, I figured I might as well convert these movies to a 1024 x ??? resolution fit for the iPad. The way I do it is to click the default iPhone video option and change the resolution and to make the file size at around 1.5-2GB. For the Ironman one, it converts and such but the audio and video are COMPLETELY out of sync and I don't know what's wrong with it :S But for the mkv, it stops like at around 30-40% and says it's done. Are there any other recommendations I could use to convert these properly/a way I can convert these on Handbrake without any problems? Thanks.
