The vzaar iPhone app lets you upload and manage your videos on the move.
On selecting the 'Videos' tab, you can view all your uploads. Tap a video for more information and options. From this screen, you can watch the video, rename or delete it, copy the embed code, or share the video in a variety of ways.
On the 'Settings' page, you can add or create more accounts, select the twitter client you'd like the app to share to, or alter your upload options.
From the 'Upload' tab, you can upload a video either from your library, or record a new one. Once the upload has finished, it will be sent for encoding. At this point you may leave the app, and will receive a notification when encoding is complete.
