Pixelpipe

From https://webapps.stackexchange.com/questions/3486/is-there-a-way-to-upload-higher-resolution-videos-to-youtube-or-any-video-sharin

This free app allows iPhone 4 users to directly upload their 720P videos to YouTube, as well as Flickr, Facebook, MobileMe, Viddler, Posterous and a whole slew of other video sharing sites. The app evens works via email and FTP. The only caveat is that the videos cannot be over 200 MB in size.

Regarding with how to use it, check out this post: http://islandinthenet.com/2010/07/06/pixelpipe-upload-720p-hd-video-from-iphone-4-to-youtube/ I recommend that post, it gives some great information on the app and how it is used.

For example:

A “pipe” is the connector between the PixelPipe app and one or more destination sites where you want your content to be uploaded. For example, I set up pipes for flickr, picasa, and Dropbox and many others.

I setup some of my pipes as default routes. This means that any media I select to upload will automatically go to these default pipes.

For each pipe I created, PixelPipe created a routing tag. The routing tag explicitly tells PixelPipe where to upload the content overriding any default routes. If you want your content routed to different photo sets you can create a routing pipe and tag for each one.

Also, given this:

since other developers are sure to create a similar product now that they know it is possible to upload 720p videos.

If you don't like the PixelPipe app, it shouldn't be too long before another solution pops up :)

According to this page, an app called SmugMug is also 720p uploading enabled, however I couldn't find much in reference to that on their site. http://www.tuaw.com/2010/07/01/want-to-upload-720p-from-iphone-4-try-pixelpipe/

No, there's no way to do that yet. Using external apps won't help either since Google has not released a full API yet with those functions so far.
