The ability to upload HD video directly from an iPhone 4 to YouTube (WiFi only) is one of the new features added by the iOS 4.1 update. You can see the result of my test of this feature in the YouTube video embedded above. Here’s a couple of quick notes about the process.
– The default is to upload a lower video quality file. This makes sense since this also means a smaller file and faster upload.
– The title, description, tags, and category fields must all be filled/selected before you can upload an HD video file
– Uploading an HD video file directly to YouTube can only be done while connected to a WiFi network.
