The proper orientation for the camera is LANDSCAPE (more wide than tall) with the 'home' button on the RIGHT. Holding the camera in this orientation assures normally looking images (both still and video) on all players.
iENG provides a warning (via a yellow indicator at the upper right) if you are holding the device upside down. iENG will automatically fix potentially upside down STILL images for you (if you prefer to take still images using the volume buttons located on top on an iPhone) but iENG cannot repair upside down video images, even though it will let you shoot them.
Since most professional broadcast newsgathering requires 16:9 aspect ratio LANDSCAPE images, this is what iENG will provide. Portrait orientation is not supported.
iENG writes your image to the devices 'Camera Roll' first, and in the highest possible quality.
Your captured media is saved in the Camera Roll even if it had trouble exporting off your device.
iENG handles all STILL images in the highest resolution provided on your device. Video images can be transcoded to lower resolutions for export as desired and selected on the appropriate menus.
Videos are exported using h.264 video compression and AAC audio compression with a Quicktime '.mov' wrapper/extension. Still images are exported in .jpg format.
From the upper left on the display...
If your device has a built in 'flash' you will see a button that will allow you to alternately toggle between AUTO and FORCED-ON flash modes. Please note that if your device detects a high ambient lighting environment it may decide NOT to allow the 'torch' to operate.

The button for capturing still images
Along the right edge...
The Auto Upload selector allows you to capture an image and have it automatically trancoded and uploaded to your home office as soon as possible, if desired.
Selecting FTP will fully automatically send the media to the FTP server that you have setup on the 'Setup' page. You will see it's progress in the FTP export-upload status section as it's uploading. Any failed uploads will remain in the FTP queue and the upload can be reattempted later when desired, or cancelled if desired.
Selecting EMAIL will automatically bring up the email send display once your media is ready to send. You can at that point just hit the SEND button to send it to the default addresses that were configured on the 'Config' page. If your image is a STILL, you have one last chance to select the resolution of the emailed image.
Video media is sent via Email at the capture export resolution, which often creates a file too large for many email servers-- YOU need to determine if your captured video is too large in size for the recipients mailbox. iENG assumes you know what you are doing, and will not stand in your way (even if you are mistaken).
Setting the Auto Upload to OFF will bring up the destination export page once iENG has finished capturing your media. From here, you can send your media via FTP, Email, Twitter, Facebook, Youtube, or just exit the page and leave the media in the Camera Roll for export at a later time.
If your device supports 'Auto Focus', 'Auto Exposure' or 'Auto White Balance' you will be able to lock those to their last settings as desired. If your device does not support one or more of those modes, the selector will be partially greyed out to indicate such.
To the right of the image preview display are three indicators which show the connectivity status of your device. The top indicator (a 'globe') indicates connectivity to the FTP server you setup (or Facebook.com if you didn't setup an FTP server).
The middle indicator shows a cellphone tower and lights up in Blue when you have Cellphone based internet service.
The lower indicator shows a WiFi icon and lights up Green when you have a Wifi Connection.
The globe will indicate either Blue (for Cellular data) or Green (for Wifi data) to correspond with where your internet access is coming from at that moment.
If the indicators are red, then you have no internet connectivity.
If your internet connection switches from Cellphone data (blue icon) to or from Wifi (Green Icon) during an upload to an external server (FTP, Email, Tweet, Facebook) your upload may be interrupted and it's possible the equipment on either end of the transfer will get confused. If this happens, you are best to fully exit the iENG app and restart your export session when you have a more reliable internet connection.
In the lower right of the screen is the FTP export-upload status section which displays the parameters of any AUTOMATIC FTP uploads currently ongoing.
Any files waiting in the FTP queue will be sent along with any automatically uploaded media when the transfers are started. When an automatic mode FTP is active, you can cancel the upload by hitting the red cancel button. Any cancelled files will remain in the FTP queue.
Just above or below the preview monitor (depending on device) is an indicator to show what Capture-export preset you have currently selected.
The Preview monitor system will accommodate the connection with external monitoring devices via the appropriate Apple cables, or a connection to an AppleTV (2nd generation hardware or newer). When an external monitor is connected, the view on the monitor is just the camera output, no menu items or buttons are shown.
It is advised to connect or disconnect any external monitors either when iENG is NOT running, or when iENG is on the Image Capture page. External monitor connections or disconnections during image capture are ignored, but to be on the safe side, avoid changes while capturing.
When an external video monitor is connected, the 'tap volume buttons for Still image' mode is disabled.
Please be aware that audio playback usually follows the video monitor and if you have an external video device connected, the audio preview of videos will be heard through the external device. Similarly if you have a device plugged into the headset jack, audio monitoring will follow to the headphones.
iENG will fully support your wired external mic. Bluetooth headset audio monitoring is also supported, but not bluetooth microphones (at this time).
iENG names exports all files with a unique filename so that they cannot accidentally overwrite other files. As you will see from the example in the image above, all files begin with 'iENG' and contain the date and time as part of the filename (24 hour time).
There is a letter in the fifth character position (just before the 'year'). Still images have an 's' while videos have a 'v'. Of course, you can also differentiate the files by the '.jpg' or '.mov' file extensions.
