Exporting HD video using a Mac.
If you go to Custom, Advanced Settings and select H.264 as the output, you get a list of mp4 settings in the Preset list. You can change the Basic Settings to create your own Preset. However, if you then go back to create another preset (or simply use one that appeared in the original list), you can't - the complete list has vanished and you're left with just the preset you created. You have to delete this preset to create another! In older versions, you could create as many user-defined settings as you wanted, and these would appear below the standard list.
Anyone else discovered this?
