Tip: Place the pointer over the Device pop-up menu to see which Apple devices can
play the selected option. Additionally, the Summary pane also lists the compatible
Apple devices.
• iPod/iPhone (VGA): This option creates video output files with a frame width of 640
pixels.
• iPod/iPhone (Anamorphic): This option creates video output files with a frame width
of 640 (anamorphic) pixels.
• iPod/iPhone (QVGA): This option creates video output files with a frame width of 320
pixels.
• Apple TV SD: This option creates video output files with a frame width of 640 pixels
with a higher bit rate range than the iPod/iPhone 640 (VGA) option.
• Apple TV SD (Anamorphic): This option creates video output files with a frame width
of 720 (anamorphic) pixels.
• Apple TV HD: This option creates video output files with a frame width of 1280 pixels,
except when the aspect ratio is set to 4:3. In that case, the video output files have
frame dimensions of 960 x 720 (anamorphic) pixels for frame rates above 24 fps and
1280 x 720 (square) pixels for lower frame rates.
• iPhone (Local/WiFi): This option creates video output files with a frame width of 480
pixels.
• iPhone (Cellular): This option creates video output files with a frame width of 176
pixels.
• iPad/iPhone with Retina display: This option creates video output files with a frame
width of 1280 pixels.
• Aspect Ratio: Use the Aspect Ratio pop-up menu to choose the exact pixel dimensions
of the output media file. The available options depend on which device option you
selected. See Aspect Ratios for Apple Devices for more information.
The Aspect Ratio setting also has an Automatic button. Clicking the Automatic button
causes the encoder to choose the aspect ratio that matches the source video file.
Important: The automatic mode for the Aspect Ratio setting is able to choose from a
wider variety of values to better match the source video (with the values determined
and displayed when this output format is applied to a source media file). For the best
results, it is recommended that you use the automatic mode for the Aspect Ratio setting.
