Here are some useful tips when using the Video app on the iPad:
- Connect to an HD TV
You can connect the iPad to your television. You'll need the Apple iPad Dock Connector to VGA Adapter, which connects to the 30-pin port on the iPad and to the VGA port on your HD TV.
- Use widescreen for some movies
Depending on the movie you watch, widescreen mode might work better. To use it, go to Settings, Video, and enable the Widescreen option.
- How to transcode videos
If you watch content in widescreen and want to maximize storage, you can save some disk space by using an application like Handbrake to transcode your videos into the largest 16:9 resolution the iPad's XGA screen natively supports. In Handbrake there is a preset in the right-hand drawer under the "Apple" section called "Universal" that is slightly less resolution than what I've recommended above (720 by 400 for a 16:9 video) but will play back just fine on both iPads and iPhones.
