Apple has launched FaceTime video calling with every iPhone 4. All that's required is a Wi-Fi connection and a person on the other end of the line running the same setup. There are many things you can do to get the most out of your FaceTime calling experience.
First of all, to test your setup and get some personalized instruction, you can call an Apple representative using FaceTime at 1-888-FACETIME. Make sure you're connected to Wi-Fi before you dial. When you're ready to video chat with your friends and family, check out this list of tips:
Apple offers the iPhone 4 in two capacities, with 16GB or 32GB flash drives. Video recording quality has been vastly improved with the addition of full 720p resolution HD at 30 frames per second. This also means that more disk space is required to store video files.
12 minutes of HD video will take up approximately one (1) GB of space on your iPhone 4. This equates to approximately five (5) GB of file size for one hour of HD video recording.
The iPhone 4 also features a front-facing camera that records video at lower VGA quality.
The iPhone 4 supports three video formats:
H.264 video up to 720p, 30 frames per second, Main Profile level 3.1
Audio: AAC-LC up to 160 Kbps, 48kHz, stereo
File types: .m4v, .mp4, and .mov
MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile
Audio: AAC-LC up to 160 Kbps per channel, 48kHz, stereo
File types: .m4v, .mp4, and .mov
Motion JPEG (M-JPEG) up to 35 Mbps, 1280 by 720 pixels, 30 frames per second
Audio: ulaw, PCM stereo
File type: .avi
